Ford Escape / Hybrid :: 2004 V6 - AC Defrost Only - Vacuum Leak
May 16, 2014
I have a 2004 Ford Escape 3.0 V6 FWD, and the air conditioning has been blowing only to defrost for a few weeks now. After many searches online, most sources seem to agree it is a vacuum leak, as the selector switch is vacuum driven if you want anything except defrost. I popped the hood and within one minute I found one open vacuum line that looks like it has been worn in two.
The line in question goes from the vacuum canister towards the passenger side of the firewall, then goes to a T connector, then a line (the one that is broken) continues towards the heater core lines to where the break in the line is. I found a picture online of what it should look like, but I am having trouble accessing the line that goes through the firewall and behind the glove compartment. I am pretty sure this vacuum line continues through the firewall between the two heater lines, but after that I am stumped.
I popped the glove box down out of the way and I see two thin vacuum lines and a small metal "can" nearby. The black line goes from a fitting and into the A/C bundle, and the white line goes from the top of the metal canister and down into the same bundle. My main question is which line controls the AC selector, and how do I pass a replacement line through that part of the firewall to make a good connection, as it seems the break is at the firewall itself with no extra sticking out for me to connect to.

I know all about vacuum leaks and such causing this problem, and I tend to think that is my problem. But isn't the temp change dial also vacuum controlled (in my case of an 06 f250 6.0) by that valve near the oil fill tube on the passenger side? I ask because, while I am stuck on defrost i can change the temp of the air that comes out still, telling me there is enough vacuum in the system to at least control that.
I also know everyone talks about checking the ESOF system for cracked lines/leaks, but this shouldn't come in to play unless I have 4WD selected or if the EFOF solenoid is bad, right? I just got done tearing the top end of this engine apart, twice, for oil temp problems and am about done working on this POS!!!

Ok, I have capped off the vacuum lines to the front hubs and replaced the vacuum solenoid on the passenger inner fender. Still stuck on defrost. I know there are several options from this point what would be the next step after what I have just recently done. Going away on a ski trip and would like to have it working properly before I go.

This has been on going for the past year. The blend works fine. Fan speed works correctly. The selection for ac, max ac, etc., will only allow air through defrost vents. Vacuum leak?

I simply cannot find a proper and complete vacuum diagram for this 2001 Escape V6. (The sticker has been removed from the car.)
The car is hard to start - very hard, but once warm it manages to run ok. There vacuum hose way down low, on the back of the block and under the starter, impossible to see but if my fingers aren't lying it's very near the knock sensor? This hose is rotten and disconnected at the top - it's just laying there kinda under the throttle body.
For the life of me I cannot a) identify what the hose goes to and b) figure out where to plug it back in. There are no empty ports I can find anywhere within reach of the floppy end of the hose.

Ok, I know I have a vaccum leak. I have manual hubs now and those lines are capped. The AC is blowing through the deforst and the pump is running non stop. I have replaced the vac pump a couple of years ago and it worked fine then. any other places to look?

I've read quite a bit in various threads about the large vacuum elbow collapsing, causing erratic idle speeds. My 2001 3.0 had that issue int he past. I shoved a 1/2" copper 45 degree elbow inside of the rubber elbow, and the problem was solved... until a few days ago.
We're now getting into the hot part of summer here. I've notice the same symptoms are beginning to return, once the engine compartment gets hot. My question is... is the large vacuum line a "hard line" all the rest of the way to the engine, or are there other places along it's length that can also collapse under vacuum?

Wife is operating a 08 Escape with about 31K miles on her. She loves the vehicle but since we bought it with 24K miles on it it has had a rattle under it. I assumed that it was the heat shield and i would get around to securing it but haven't yet. Here's the question. I noticed recently that about mid way back under the pass side there is a black spot developing on the concrete where she parks every day. The vehicle does not sit and idle there. Its started and is moving in about 20 every time. I have not got under there yet but was looking for possible answers as to what and where to look? Flex pipe? Bad seal on exhaust? If this is the case should a 31K mile vehicle have this issue? The vehicle is louder than a 2.3L should be but from reading that seems normal. If it is the flex is this something that a novice wrench can do?

I set out to do a coolant flush but ran into an increasing number of problems. When I went to replace the thermostat I discovered one of the three bolts would not come out due to the inside thread on the thermostat housing being stripped. I purchased a brand new housing and O-ring.
When I reinstalled the thermostat (also Motorcraft brand) with the above O-ring and attached all the hoses I had a severe leak between the thermostat housing and the intake hose connecter. I diagnosed the problem as the O-ring slipping off of the lip or ledge inside the thermostat housing and not sealing all the way around.
The Motorcraft O-ring seemed like the diameter was too big for the interior lip of the thermostat housing because the ring would pop up on one side whenever I tried to fully seat it on the interior lip. I went to AutoZone and purchased an orange Duralast O-ring, and while it seemed to be a little smaller diameter than the Motorcraft it too slipped off when I tightened down the housing.
I have tried everything, and every time I tightened down the housing I did it very slowly and carefully doing an 1/4 turn at a time with the three bolts but still the O-ring would slip off.

Vehicle: 2001 Escape 3.0L V6
I'm listing here the obvious that has been changed already:
1) Valve cover gaskets
2) Oil pan gasket
3) Timing chain cover gasket
4) Upper and lower manifold gaskets (not oil related but changed)
5) PCV valve
6) Washed engine twice to remove everything and make sure nothing else burning
Problem: I still have a small leak from the top that causes smoke near or around the #4 COP on passenger (left side of the motor). But we do see some oil coming from near the PCV valve. It makes no sense and after reading what caused smoke on that side of the vehicle I changed the Timing chain cover gasket (which were finished anyway) and while was at it the oil pan but to no avail. Smoke and leak still there.
Probably not: I know that it is not the head gasket because there is no sign at all; I've never lost a drop of coolant and there is no smoke from the exhaust in back.
Suspicion: Could it be the oil separator where the PCV valve connects and makes it's way around to the other side? Is there something I am overlooking? There can't be many other places for an oil leak like that.
Coincidence ? : Even after changing all the COPS and spark plugs I found oil in the #4. However smoke was there before. I thought maybe a cylinder gasket I got second opinion from my mechanic says no not cylinder...
Engine runs well except for misfire in #4 but comes and goes. I think when oil builds up.

My 2010 2.5L FWD Escape has oil on the steering boot and has run down on crossmember (?) It is equipped with Electric Power Steering. This appears to be coming from the rack and pinion but does it have fluid in it? How can you add if it does. I have 96,000 miles on the vehicle and except for a drivers door actuator and scratched drivers glass, this is only problem.

I was just changing the oil on my wifes 2008 Escape and noticed a oil leak. At first I thought it was an oil pan gasket,But its higher than that. Then I thought maybe an axle boot but it's also higher than that. It's on the passenger side about the middle of the engine right under neath the biggest pulley.
Its a cylinder shape mold coming off the engine about an inch long with a bolt on the end of it. I'm not seeing oil any higher than that and seems to be coming from there from what I can see. Is this something common with the Escapes?The truck has 55,650 miles on it and this is the first issue so far.The wifes first escape we traded for this was an 01 with 200,000.

I have a 2003 Escape Limited 4WD with approx 163K on the clock. It developed a tranny leak from the front driver's side axle. The seal is new and in good shape as I just replaced the axle and seal a few weeks ago. (I checked the shaft size and surface finish of the axle and it is in spec.)
I just removed the axle tonight and discovered that the problem seems to be the bushing just inboard of the seal in the tranny. The axle has movement up and down when inserted. (Not good!) This is allowing the fluid to leak from the seal.
Here are my questions. Is this a simple DIY fix using a slide hammer type of puller (or similar), or is it time to take it to a tranny shop. I can not seem to find a replacement part listed anywhere.
Also, with this much mileage, should I have the tranny reworked as a precaution if this repair requires dis-assembly or should I just address the leak and think about dumping it? I would prefer to keep it as my kids are now driving age and this is primarily their vehicle. (It has been a great little truck!)

2004 Ford Escape 2WD 3.0L with about 81,000 miles.
Problem: 2 possibly related
1) If warm up (get to about 190+ degrees) and then cut off engine. Does not start. If I wait about 30 secs and play the gas pedal, then I can get it to start with high revs and after about 15 secs runs normally. Or, I can disconnect the air intake and it'll start fine. But if you stop and try to start again, no joy unless playing with gas pedal.
2) After driving about 20-25 mins, it seems to randomly stall-out while going about 40 mph. When it stalls out, it will restart again after about 30 secs.
Note: Neither of the above throw any codes.
Here's my problem chart after mining the other posts:
Thing to replace/do //// No Code /// Stall while driving /// Won't restart when hot
Fuel Pump //// Yes /// Yes /// Doubt it
Fuel Filter //// Yes /// Yes /// Don't think so
CKP Sensor //// Yes /// Yes /// Yes
CMP Sensor //// Unlikely /// ? /// Possibly
ECT //// Maybe? /// Yes (if too hot) /// Yes
IAC Valve //// Unlikely /// Yes /// No
Thermostat //// Yes /// Yes (if too hot) /// Yes
MAF sensor //// Unlikely /// No /// Yes
What I've done:
- Well, I started looking at the vacuum lines and they were crumbling so I replaced all those (to EGR and all that).
- There is a mystery line that appears to come up from the canister and go to nothing--is this some kind of atmospheric vent?
- My cheap scan tool also shows engine temps getting up to 216 degrees if I make it work (idle high at 2000+ rpm), so I'm suspicious of the cooling system and thinking maybe the ECU is shutting down to avoid overheating.
I'm going to start with flushing the coolant and replacing the ECT and thermostat while doing so. This is relatively inexpensive and ECT can do weird things. The restart problem is consistent, so I'll know if I fixed that right away.

Lights come on when the ignition is on, regardless of the position of the headlight switch. They shut off about 1 minute after the engine is shut off. The warning chime dings the entire time until the lights shut off.
I want the light to work with the switch and not come on all the time.
It is not just the daytime running lamps. High beams also work with the headlight switch in the off position, ignition on.
Ignition off, the headlights switch functions as it should.
I bought the Escape about 1 month ago. Dealer purchase so I don't know how to get a hold of the previous owner.
It only has 51,000 miles, very clean and all service records.

I had to replace all brakes because the bleeders were rusted in, wouldn't come out. So I bled and re-bled, but the brake pedal is still squashy and goes down too far if I have to stop from any speed. I even used my vacuum pump for evacuating air conditioning systems, pulled quarts of fluid through all the brakes-definitely no 2004 vintage fluid in there any more! Yes, I made sure to never pull the master cylinder reservoir empty, which would let in air. I always start from right aft and end up at left front, in order of bleed first. No leaks, the fluid level is always where I left it on previous session. I must be missing something...How can there still be air?

Wife come home the other day after leaving for work with the truck no going past 20KM to 30KM.. After some investigating it seems to be in Limp - In Mode. There was a Check-Engine light & after further investigation found a Vac hose with a leak, repaired this & test drove. Same issue.... then there was a loud hissing sound from the engine area so I investigate & now found the EGR sensor (DPEF pressure sensor ) had blow a hose & fried the sensor.
New sensor was replace along with 2-hoses cleared the engine light but the truck still will not go more then 20KM or 30KM max.. I checked the EGR valve with vac pump & engine stalls or so the valve is good. I have left the neg cable off the batt to try & clear the Limp-In mode without success. Looking for a way to clear the limp-in mode or do I need to clear it with a scan tool?

I have a 2004 Ford Escape XLT V6 and I am experiencing a major loss of power in the vehicle. It idles smooth at about 1000rpm's but when you drive it , the vehicle won't go over 30mph and has a significant miss to it. I replaced the fuel filter, put in some Seafoam and took it for a drive and it still did not have any power and I blew out the EGR valve on the test drive. I replaced the EGR valve and the problem still remains. I hooked up a handheld computer to it and I got a P0300, P0304, P0305, P0306, P0316 and a P0355 error codes.

I noticed the lights were staying on after the switch is turned off and engine off. I thought the lights might just stay on for a few minutes, they were still on an hour later and now I can't unlock the doors with either the key fob or the key. Not sure what to do next.

My son's escape has been parked for about 6 mos... alternator went out and I refused to pay to fix it due to some disciplinary issues with him. Anyhow, yesterday I went out to go look at it and the hood won't open. When I parked it I took out the battery and shut the hood. Never had an issue opening the hood prior.
When I pull the lever, its real tight - like the cable is not really moving or if it is, it cant be much. I'm afraid it might break if I keep pulling. I tried having him pull it while I pushed and pulled on the hood, still stuck. I have no clue why or how it is stuck, but wondering on any way to get it open. I can't really see in there...through the grill or under the hood.
