View 9 Replies1997 Ford f-150. No heat.
I have replaced Radiator (Leaking)
New heater core (Signs of leaking when I replaced it)
New blend door (Why not...I am already in there)
Actuator motor works fine
New thermostat.
Both heater core hoses are hot. (same temp, feels like)
My next step is going to be water pump. I read where some have replaced pump and found that although no leaks were found the fins were deteriorated to the point it would not work. Truck does not overheat. Coolant level is fine. Cab gets heat for a few seconds then quits.
Money is not an issue so I don't mind throwing a few parts at it. What other parts are left?
Temp. control switch
Water pump?
I have the P1518 code for Intake Manifold Runner Control. I can not seem to find if have the actuator itself only the electronic control which, I take connects to the actuator. Is the electronic portion the only thing that needs to be changed and clean the actuator butterfly with the manifold off, or does the actuator need to be found and replaced?
View 3 RepliesI come over from the old school forum (48-60) with a question about a new to me 1999 F150 XLT 5.4L, 4x4, Auto. Truck has ran awesome for a couple of days. Truck has in excess of 410,000 miles but don't let that mislead. I believe the engine has been replaced sometime along the way. Yesterday I was driving and it just stumbled and stopped. After sitting for 5 minutes it started again, stumbled and stopped.
Today I checked the following:
- Fuel pump/relay - both work
- Dropped gas tank and replaced fuel pump strainer and fuel filter
- Fuel pressure at rail remains steady
- No codes present and no SES/CEL on.
Could this be a plugged EGR valve or IAC valve? I have had similar issues on Tauruses but it always threw a code when it did. Could this indicate a cat issue?
The Speed Needle works fine. But...the Odometer part quit some time ago. I can't tell what my fuel Mileage is now. How to troubleshoot this problem?
Things that might affect this problem; Transmission skids loudly when going in and out of 4-OD. It could be the Torque converter clutch?
The Gear shift lever is sloppy. Doesn't fill me with Confidence.
Brake fluid warning light is on most of the time. Fluid level is up hi though. Driver door mirror control switch don't work in one direction Who on this Forum has a Switch for me?
2003 F 150. 5.4 motor. 4x4. 270,000 miles. Climate control.
The A/C is ice cold.. For the first 12-15 miles, and then it shuts off and is warm.
I had it recharged at the shop just to be sure. When it works, it blows out the vent at approx. 42 degrees.. nice and cold.
This problem happens every time. Turning the climate control off and then back on doesn't work.
Shutting the truck off and then back on doesn't work. Wait a while.. Not quite sure how long, but the next time I drive it, it will work again. For about 12-15 miles and then blows warm again.
A bit of funky , moist smell to it when it blows warm.. Typical A/C smell I think.. The box could prob use a cleaning.
The AC works, but just not well enough on a really hot day. On a day in the 90s I have to put it on Max AC and even then it does not cool down for a while and the air out of the vents is not ice cold.
So, it works, but I cannot tell if there is something wrong or not. I recently put in a can of AC Pro and it did not change anything.
My digital odometer is funky! Sometimes time it works sometimes it doesn't. Sometimes it works on start up than after a lil while it fades out.
View 7 RepliesI was driving my f150 with the AC on, it has a 4 position fan switch. Lo, 1 , 2, and Hi. The fan only works on Hi. I don't think its a fuse, so what are the possibilities ?
View 3 RepliesSo my a/c works some times. I'll get in it in the morning, turn the a/c on. It works great, ice cold blowing hard. Then I'll turn the fan down from high and in a minute or so the cold air stops and it blows warm. Then for the rest of the day it wont blow cold air(i get in and out of my truck a dozen or so times through out the day turning the truck off each time). my dad has a freon pressure gauge. We checked it and it had good pressure. the blue gauge was at 50 and the red was a hundred and some i forget, but dad said "that's where it should be" so i guess that's not the problem. I am wondering if there is switch bad or a sensor. Its an '02 fx4 f150 4x4 140,000
View 1 RepliesGot an 01 f150 excab with the 5.4 as of lately sometimes when i turn the 1-4 blower control know it wont do anything on heat or ac than other times it will work like it supposes to?
View 2 RepliesI got a 2000 F250 XLT that the AC fan only works on high. Same thing in heat mode. Is there a relay for the other speeds that I need to check out?
View 2 Replies2002 f150 7700 with 5.4 triton and 4r100 tranny started chugging under acceleration and now stalls when put in D, 2 or 1. park and neutral are fine and reverse works perfectly.
Now when I put it in drive it chugs and stalls immediately... 1/10 times it will keep running but chug violently like its running out of gas. will get worse and stall if you press the gas. i can light the tires up for a block in reverse however.
Changed coils 1 2 and 3, IAC, bank 1 knock sensor, camshaft position sensor
My 2001 f150 super crew, the heat only works on speeds 1-3. All 4 speeds blow air fine, I'm talking about the temperature. not the blower. Could it be the heat resistor?
View 4 RepliesMy 2011 sonata rattles when starting. It sounds like noisy lifters and quits after 2-3 seconds. It does not do it on the first start-up of the day, but on subsequent starts when the engine is warm.
View 7 Repliesmy turn signals only work with the steering wheel tilted all the way up. It works for me, but my wife drives the truck mostly because we live a mile from her work. The dealer said it was a "peanut connector." And can someone walk me through the steps to fixing it?
View 8 RepliesHere's what I have : 2003 F150xlt V6. about 65K miles.
Here's what happened : Drove it to the hardware store to pick up some stuff. Stopped in front of the garage. No abnormal indications during that trip at all. Decided to back to the garage and when I started it, it "ran" very rough and died in about 5 secs. Started again and chugged for about 2 or 3 secs. Tried a third time and would not run.
Here's what I've got : No CEL. all gauges indicate correctly. No anti theft blink. more than a 1/4 tank of fuel. in south central PA about at 35 degree day. parked level.
What I've checked : Wife turned the key on, I hear the fuel pump run a couple seconds with my ear in the rear wheel well. truck turns over fine. no start. turn the key off, about a two second buzz from the idle air control valve. when the key is turned on with my finger on the fuel pump relay, I feel it shift. I have pulled it and looked for corrosion. no problem. checked applicable fuses (visually).
I have tried to start with the IAC and MAF disconnected individually. tried to start it with a different key.
I have not : Banged on the tank to free up the pump. (I don't suspect it at this point)
I have not checked to see if there is fuel pressure at the fuel rail. Where is that schrader valve? I miss my books.
I have not verified that I have spark. What's the easiest way?
I have not modified my air intake in any way.
I'm headed out to a parts store tonight or walmart to get another scanner. I think my best clue here is the buzzing IAC. What's that mean?
It driving me crazy. Every 10th start of engine it cranks over and over before it fires up, no codes, changed plugs, wires, crank trigger, fuel filter, upper and lower intake gaskets, injectors, iacv. I have no clue. Runs great all time just starting issue every 10th or so start takes 10- 15 seconds to start
View 2 RepliesI have a 97 7.3 ... I've had it about 2 months now and now it wont start! It will start and idle for 2 seconds then start knocking and die! I had a buzz test ran on it and all is good. I also checked my Icp and checked my uvch harness with my multimeter. Before this it would run ok but seemed like it had a miss and a lack of power. On start up if i didn't have it plugged in it would smoke white smoke horribly. I am thinking maybe my IDM. I need my truck for work .... I had it hooked up to a scanner and it said faulty IDM.
View 1 RepliesEvery time that I hit the brakes, the headlights flash and the horn blows for about 30 seconds. I am guessing that it has something to do with the factory alarm? I do not have a key pad. It is a 1997 F-150.
View 3 RepliesI recently sold me 91 F-250 and got into a 98 F-150. It's a SuperCab 6.5' bed, 4x4 off-road, 3.55 gears, 5.4 v8 auto. I love the truck, but I am having an issue with a noise at startup.
Every time I start the truck it fires right up but it makes a grinding noise AFTER it starts for about 3-5 seconds. I thought the starter wasn't disengaging in time so I replaced it. The starter I took off was fairly new. It's teeth had just a little wear and the flywheel had no visible wear. I put in the new starter and there was no change at all.
I also changed the oil and filter using Motorcraft 5w-30 oil and a Motorcraft filter. I also started it without the serpentine belt to rule out a pulley bearing. What the noise could be? The truck runs absolutely excellent, by the way.
