So I got in my truck yesterday and i started it like normal and turned air on. The air will not blow out of the vents but only the defrost vents. I have checked all vacuum lines and good, my 4x4 engages and no issue with it locking in. I am Puzzled on what it could be?
View 3 RepliesMy 1999 F 250 5.4 liter. I know I have a vacuum leak because whenever I accelerate the air conditioning coming from the vents switches to the defroster. So my question is how do I go about finding the leak? My hubs in the front are manual so I know I don't have lines going up there. I do have some mechanical capabilities I've changed water pumps alternators brakes etc. But never anything with vacuum lines or a/c.
View 14 RepliesI have a 2005 Ford F-250 Diesel 6.0 my ac works fine but after working a while the air quits coming out of the vents. It happens every time I go on a long trip with the ac or heater. Is like if a duct damper closes because I can hear the motor blower going. The entire ac system is new but it was doing this with the old system....

View 2 RepliesMy new to me, 2005 F-250 windshield washer nozzles don't work. I have replaced the windshield washer pump, cleaned out the washer fluid container and rubber filter screen, blew air through the lines and the passenger side nozzle barely sprays and the driver side nozzle does nothing at all. I guess I have clogged nozzles. What is the part number or place you bought them? Looked online and everything I can find is so generic.
View 14 RepliesRecently had extensive work done on my 2005 F250 PSD. 4 injectors replaced, fuel regulator, and STC fitting on HPOP.
Got the truck back, and the fuel gauge, and "distance to E" display are working intermittently.
When the truck went in for repair, it was about 1/8 tank. After repairs, shop put about 30 miles on the truck.
I picked it up, and the gauge read E, and display said 0 kms to E. I filled the truck up, and the gauge still read E, and said 0 kms to E.
I then drove for a while, then powered down, and back up again, and gauge read below E (like when truck not running), and display had 4 dashes...no numbers, for distance to E. I powered down, and then back up, then it read 696 kms to E, and gauge working normally.
This morning, on a cold start, the 4 dashes, and empty reading returned. I shut off truck, and restarted it, and it started working again.
Could the shop have damaged the sending unit, while driving 30 miles, with so little diesel in the tank?
Last week I flipped the fan switch on and noticed that only hot air was coming from the vents, even with the control set to AC. The vent control switch seems to work fine directing the air but only hot air. The temperature control does not work. The exception is when I put it on max AC I get cold air. I can't be the only one.

My question.... I noticed a strong ammonia/super glue like smell floating around in the cab about the 3rd time i drove the pickup. Since then, it seems to do it intermittently. My first assumption was it was coming through the vents. I have done a couple experiments, and I don't believe this is the case. My wife and I were driving yesterday and she thought she noticed the smell again. while I was driving she started checking all the vents, and nothing. But when she leaned clear down near the speaker hole in the door, she said she could really smell it.
What could be causing this? I'm assuming if it was the AC it would be coming though the vents. And at this time, I don't think it is.
My heater vents have been acting up. I have read that there may be a vacuum leak that causes the blend doors to default to defrost...
Where the vacuum line fails? I have ESOF 4x4 and that is still working. I think there may be a correlation between engine vacuum and my vents: at cruising or idle the vents work ok (not perfect) and under acceleration (less vacuum) the dash vents stop blowing.
I thought that the blend doors had their own vacuum pump, so I do not know why things change at different amount of throttle?
2006 F250 with the dash controlled 4x4. I typically keep the front hubs locked on this truck. I have recently noticed that when shifting into 4x4 that the a/c or heat will switch from blowing out of the vents to blowing out of the defrosters. Any clues how to fix this?
View 1 RepliesAir is only blowing through the defrost vents. No matter what I do - try to turn vents, A/C, heat, fresh air, recirculating, etc. Assume it's a switch or fuse issue somewhere. How to fix it?
View 11 RepliesI have a 2006 F-250 Super Cab with climate control. The last three years when the temp exceeds about 85 degrees outside it acts up. It will switch from the AC vents to defrost and blow normal air through, not ac cold. Then it will switch back, when doing so I can hear the internal deflector shudder. It will do this every few minutes. It is extremely annoying. All other times of the year it works fine. My local dealer had the truck last year, but could not find anything wrong. I have used the search and also Googled and while I find similar problems nothing exactly the same.
View 12 Replies2011 F250 - AC works perfect sometimes. When it does not there is not clutch action or signal. Pressure is good, will work for many hours when working. Sometimes it will not turn on at all. I'm looking at installing a resistor in the evap temp sensor circuit.

Took the shift motor off and freed it up and it worked fin till today. Changed the shift motor and still nothing. This truck has been nothing but problems since I have had it and now this ... Truck is going on the market soon and would sell better if the 4x4 worked ...

View 14 RepliesI have had the ABS light on for about a year now. I looked thru the forums and found that the typical reason if a faulty rear VSS (vehicle speed sensor). I found a replacement part online and got it ordered and replaced the original part. Simple 5 minute fix, but it didn't fix it!
Now when I get in and start the truck the ABS light is off, but after I drive off about 20 yards the light comes back on and stays on.
The other day someone stepped out in front of me at a cross walk and I hit the brakes pretty hard and although the truck stopped in time, the rear wheels locked up, so I'm thinking the issue is at the rear.
I came home from a week's vacation and towed my 16' toyhauler to and from the Sequoia Nat'l Park ... no issues during the entire trip. Guestimating about 5 hours after being home, everything was unpacked and the truck/trailer locked but still hitched ... suddenly the alarm went off ... all by itself! Using the ignition key, I was able to start/stop the 6.0l diesel motor, but the alarm kept going.
I pressed the lock/unlock buttons but still the alarm was going off! I repeated this a few times and concluded that only recourse was to disconnect the batteries. That stopped the alarm. While doing the disconnecting, I detected a faint electrical hot, maybe a burn kind of smell but no smoke of any kind.
I'm worrisome about reconnecting the batteries to see if the truck is back to normal ... I will probably just have it towed to a mechanic ... in any event it's going to go somewhere to be looked at this coming Monday.
2002 F250 SD 4x4 crew cab, v10. 4x4 not working. Replaced switch on dash, not the problem. Some of told me it was the vacuum control module. Not sure where to start.

My light on the overdrive is not coming on and the overdrive does not seem to be working. I had a new transmission installed a few weeks back. Wasn't working prior to this.
2000 f250 7.3. Today I tried using the 4x4 and no light or anything. Here is what i have tried so far. Swapped the relays and also swapped them with the towing relays with no change. Not getting any voltage to the t-case shift motor at the selector switch testing between pins 2 and 3 there is 4.3 volts with switch in 2wd 2.4 volts at 4 high and 1.09 volts at 4 low. Where to go from here? it worked fine 3 days ago.
