With the few hot days we have had here lately, I have noticed that after about a minute the AC will go warm and I will have to rev the truck up when it does to get it cold again. It seems the compressor is disengaging. I noticed that the condenser has a big gash with a tube ripped open on top. I know it needs to be replaced, but could that be causing the compressor issues? It's a 2003 7.3L.
View 8 RepliesI have and 05 F350 4X4. I put it into 4 wheel drive high yesterday to make sure every thing was working correctly and it was so I went to 4 wheel low and that worked fine. Problem is it won't come out of 4 wheel low. I didn't try to go back to 2 wheel when I was in 4 high. What to look for? The truck has the electric switch to engage 4 wheel.

The dash controls light up normal, fan comes on, etc. I am just looking to see if there are any common failure points. I know it COULD be low on charge, clutch could be bad, etc. I am just checking if there is a common failure with these trucks AC system.
View 10 RepliesOk AC wasn't working took it to a mechanic told me the the compressor was missing a clutch he recommended i put a new compressor. Is it possible just to put a new clutch in it and if so do i have to remove the compressor to put the clutch on it.

View 13 RepliesI am not sure which it is but I cannot turn the pulley by hand. How do you tell if the pulley is bad or the whole compressor? I went out to start the truck and it wouldn't start. It died so I restarted it and then I seen the smoke from the front of the truck. I opened the hood and the flipping belt was just hanging there. Is there a way to just bypass the unit for now? I wont be needing the AC till summer and that is several months away.
View 3 Repliesthis doesn't make any since to , what's going is, sometimes the AC starts blowing warm air, I found out if I goose it I can hear what sounds like the damper door slamming shut, then AC starts blowing cold again. I changed out electric vacuum pump, but it still does it, starting to get worse & its hot.
Truck is a 2002 f250 powerstroke, the way I understand it, is only thing vacuum pump is supposed to control is AC & 4 wheel locks, my truck is only 2wd. I don't understand why when when I goose it ,it goes to working, what can I do to fix this.
I just found out the " heat and cool "adjustment is electrical, not vacuum, it goes to something under dash, but what it is, heat strip, reastat(sp)??? where and what damper am I hearing. It is not like heater is on ,not that hot, feels like ambient temp, I am at a loss...
Trucks compressor kicks on and off and won't stay on no cold air at all do i have a leak ? The truck came whit a new canister that mounts in front of the air box could it be that?
View 8 RepliesOf course my freon all leaked out of the AC compressor and it is squealing pretty bad. I did not want the serpentine belt to break due to a seized compressor so I looked for a bypass pulley kit. Naturally they make one for both gas engines, but not for the diesel. So out comes the string and sharpie, and trips to 2 different auto parts place to get the correct length belt after trying several that were too short. It's 103 inches (8 groove) for future reference to bypass the ac compressor and upper extra pulley. 7.3 diesel.....

AC will blow cold, then shift to blowing warm, muggy air, then back to cold. Seems to be some relationship with throttle movement. Cruising steady ac seems normal. Multiple throttle shifts in changing traffic seems to trigger the warm air. Once accelerate back to normal cruise, can feel clutch/compressor shift and blows cold again.
Any ideas? I have read a possible cause can be the ac clutch can wear and need to remove spacers? Is this a DIY job? What about the ac clutch relay switch? On reading an online repair manual, seems that the clutch is magnetic, and if no battery power to clutch, it removes itself from compressor?
Just had an EGR delete kit installed. Any relationship to this and ac problem?
Got a 06 F250 V8 Gas. Went to turn AC on the other week & got warm air out vents. Put 1 can of 134 in & the gauge on the "kit" said it was in the green. It was working last summer. You can turn the compressor "face" so it's not locked up, but it's not kicking in. Swapped the replay with another one & the 10a fuse in the fusebox under the steering wheel is good. Is that the only ones? I find it hard to believe that it's something serious. We did change the belt a few weeks ago & I was hoping that we had pulled a wire loose. The vacuum line that plugs into the heater hoses is plugged in.
View 14 RepliesI have a 2001 F-350 S/D w/7.3. Question is... Is it possible for the mode switch ( one controls floor/ defrost and A/c ) to not function or should I say leave the a/c on even if it is not in a/c position? What I have noticed was that when it is in the floor mode or the vent mode (not the floor/vent) the compressor does not come on. When it is in vent/floor or either a/c modes it does. Is this normal... I don't think so though I do know anytime the a/c is switched on compressor should come on but no time without a/c being on.. Maybe I'm wrong
View 9 Replies1999 F250 SD 5.4 with 140k miles. There is a triangular plate with a bolt in the center and and what looks like a bolt in each corner of the plate.
Two of three bolts in the plate are missing and the third is loose allowing the plate to spin freely. Center bolt is tight.
Gotten to the point it's really noisy. Can the bolts be replaced in the plate or should I just go ahead and replace compressor. If bolts are replaceable what size?
I just brought home an 04 F350. It is a V10, 6 speed, with 30,600 verified miles on it. It runs and drives fantastic, and that V10 is impressive! I am very impressed. I have noticed that the compressor cycles, even with the dial in the off position. Is this normal for the super duty, or is something amiss? If something is wrong, what direction do I look in?
View 13 RepliesI need diagnosing why my A/C isn't working. I'm wondering if my clutch staying engaged has burned up my compressor before or after my clutch went bad. I don’t think it’s the air gap issue because I took my clutch off and checked and there were zero washers. I guess somehow I re-installed it with no washers maybe the last time I fooled with it.
I've only knew to check the air gap trick and when that didn't work, I wasn't sure what my next step could be. I tried looking at the high side pressure switch connector to see if it was burned up and it looked ok.
Can track down if my compressor is still good and replacing my clutch is the only thing I need to do or if I need to replace my compressor? Or if there's something else that's totally unrelated that I need to check?
Need to replace the ac compressor bearing/pulley on my 2001 f350 7.3. My question is do I need a special tool like a pulley puller or is there another way to remove pulley? I already have the clutch assembly removed as well.
View 1 RepliesI guess my AC Compressor is about to the bed. AC works good however there is a lot of rattling going on. Been driving it like that for two months plus expecting it to fail.
Just not sure how long I should let it go. If the compressor pully fails on the road I will lose my serpentine belt and the ability to put the spare on and I will be stuck for sure.
2008 F250 XL 5.4L .....
I have a 2007 Ford E450 Superduty Box truck with a V10 and 70,000 miles. For the 6 years I have owned it, the AC has always been ice cold. This summer it will not blow cold under any driving situation.
When the AC is on AC, AC max, or defrost, the compressor clutch constantly engages for 1.5 seconds then disengages for 5 seconds. I bought a can of refrigerant and added only about 1/4 of it to reach proper psi for the current temperature.
If I remove either the high or low pressure switch clips, the compressor stops engaging. Is it possible that one of the switches has failed in that it is activating at an incorrect pressure? Unfortunately our local Ford dealer here is notoriously devious and while they may fix the problem, I will probably have an entirely new system by the time they are done.
I've ruled out coolant, air gap does not seem to apply and both hi and low pressure switches are active. What am I missing?
Bought a 2014 SD 4x4 in December of 2013 and this is the second time the big girl has been to the shop with A/C problems. First time it was the evaporator about three or four months ago. During the last few weeks of the summer I began to smell something strange (like band-aids) when the A/C was on and it lingered until the next re-entry. ALso, began to hear a slight hissing noise when the compressor was kicking in and out. They replaced the evaporator, smell remained as they said it was the refrigerant I was smelling. About two or three weeks ago the smell got slightly "larger", and last weekend she would not cool. This is the fourth time shes been to the shop with other problems such as the My Touch system..............

View 11 RepliesIts a 2001 f250 with a 5,4. I just recently put a new shot block in it, the short block is a svt short block for an 01 lightning. every thing off old motor went on new svt block just fine, and it drop in just fine. only it will not warm up i let it run for 45 min the other day and on the gauge it would not come past the c. and i do believe the gauge to be accurate because the heat in the cab sucks and the top rad hose is just warm, not as hot as it should be. I've already put 2 new thermostats in it so I don't believe that to be the issue either.
