Ford :: 2007 F150 - No Cooling Of Air / Air Conditioning Compressor?
Jul 2, 2011
2007 Ford F150 half-ton. No cooling of air at the outlet of the ductwork. Freon charge is good, I watched the tech pull the system down and hold it for the prescribed time period. Compressor will not start. I am being told that this means a failed compressor, but I am of the idea that the pressure switch for low pressure must have failed, or the orifice is stopped up. I am also being told that the compressor, evaporator, and orifice tube needs replaced in order to remedy this issue. The counter man at my local parts house cannot find in his computer any pressure switches, kinda making me think that everything is in the unit. In short, if I can avoid buying the compressor, I would like to.

Have an issue with my front air con not working.....
When you start the car there is a rattle/squeaking noise, this sounds like a worn pulley, when you press the air con button to turn it on the noise stops. It does not make any sound changes to the unit/engine to indicate the compressor engages and the is no cooling from the unit.....
Is it a new compressor or is there a common fix for this issue?

I have a 2003 Model F150 4x4 that has always ran good for me, and has only had minor issues ever since I've had it. Not too bad considering it has 266,xxx miles on it and running 100 miles a day on the original motor & transmission.
Here's my problem - my air conditioning will only blow thru the defrost. I can hit vent on the control panel and it will blow thru the vents, but if i hit max ac it switches to defrost. I live close to Memphis, and it has gotten super hot around here and i really need this to work correctly. I have looked under the hood looking for messed up vacuum lines but haven't seen any that looked bad.

My A/C takes 10 minutes to kick in after turning on and then only works if the car is running at a stoplight or otherwise stationary. I've tried adding coolant and changing the cabin air filters.

I just found out that the air conditioning compressor is broke in my 2006 prius and its going to cost $1800 to fix it.. I am not in the loop here but that seems ridiculously high. I mean i save money at the pump but all that money just went out the door if i get this repaired. I am really contemplating trading the car in rather than deal with that expense..

My sons 1998 nissan altima has engine coolant leaking from the air conditioning compressor my best guess is a leak in radiator has slugged the compressor and both are toast . I see there is separate cooler for ac is it possible to isolate that section while repairing so he can still drive to work (short distance less than mile) while I find replacement or is it not possible...

Ok here is the issue, my girlfriend owns a MK4 '99 Jetta. Through the search I was able to figure out why she is having so many issues with her door locks and how they can be fixed on the cheap..thats awesome. But here is the problem. She was driving down the road the other day, A/C working...then suddenly it stopped blowing cold. Fan is still working, just blows hot air. She said it started blowing warm suddenly and hasnt been getting warmer through out the past days or anything.
With the hood popped and the a/c on, you can see that the compressor isnt engaging. The car makes a noise like its engaging the compressor, but nothing is happening that I can see visually. Seems as if the compressor is not getting the signal to engage. It sounds like its trying to make the compressor kick on about every 5 seconds or so. Basically that initial clicking sound that your hear RIGHT before the compressor comes on when its working normally.
We have checked the fuses and no luck with those, all look good. Seems like its an electrical issue to me. What this may be? Bad pressure switch? Low pressure in the system? I know the car has had the compressor replaced before...and the clutch seems to spin freely when the car is off.

My 6.0 is cooling poorly . Clutch is engaging , condenser free of obstructions, static charge L95 , H. 105. Running psi at 94 ambient is 50 and 225. This morning with cooler ambient in mid 70's it was 40 and 200. I'm thinking compressor .

I have a 2000 F-150 4.3l and a/c compressor will not come on. I checked the pressure on both high and low side, low side is sitting at 90# and high side at 100#, with nothing engaging on clutch. I turn the fan to max a/c and fan to high and light comes on on dash for a/c, but I can't hear anything engaging on compressor and clutch looks like it is standing still while belt is rotating on engine. Had to check here to get fuse schematic and check fuses, but beyond that not sure what to do next.

Having issue with ac system cycling on and off while traveling up hill, slopes, etc?? Have a 98 f150 with 4.6 auto and past several months ac acting weird. Its been really hot, ac still is cold but not sure why cycles on and off? Just goes off for several seconds then back on, does not shut off altogether just seems like compressor shuts off intermittently.

1992 f150 4.9L, bought it a couple of months ago knowing the ac wasn't working PO had it converted to 134, said it worked great until they put on the bodylift. Compressor clutch is working, I'm sure I have some blend door issues but I've bypassed the heater for now.
AC on max, outside temp 85*, engine off high/low at 100psi, engine at idle low 55psi high 125psi, center vent reads 93*. When engine at apox. 1800-2000 rpm, low 35, high 180, center vent reads 85*.
My guess is the compressor is worn out. Is there another way to test? If I do replace what else do I need to replace? I'm hoping there's something else I can do/check before replacing the compressor.

The Truck: 94 F-150 XLT 5-speed 300-I6
The Problem: AC blowing hot air.
What I've done: Start the truck, look at the compressor, (looks like it's spinning to me), engage the AC, look again (yep the pully on the compressor is still spinning).
And that's pretty much where i stopped, cause i don't know what i'm looking for, should i be seeing it not spin if it where seized, and whats next on the list to check.
I assume that it's not seized at this point and it must be something else, like a control, keeping it from working.

I bought a 1977 Ford truck a couple of years ago. It has factory air, but the compressor was removed and the hoses were capped and/or poorly taped off when I bought the truck.
I got the bright idea, I'd try to get the air going, but I didn't know anything about a/c systems. I bought a York type (same as what it would have had originally) compressor from Autozone. They told me it was for r134. I put it on the truck along with a new filter/dryer and new expansion valve.
I took the truck to the local shade tree mechanic and he stuck a el cheapo vacuum pump on it for a little while and threw some oil and two or three cans of r134 in it. Well... since then, two summers have passed and it has never worked right.
The compressor really vibrates at low rpms. The air is just barely cool enough to tease me into thinking I have air conditioning. I know this sounds odd, but it seems to work best after I've sat at a stop sign and then take off. It's like idling the engine allows it to "catch up to itself" and then when I drive about 30 mph after a stop sign it actually blows pretty cool for a couple of minutes. But at highway speeds it isn't cool at all. This seems to be the opposite of what I've read. I had the heater & a/c box all apart changing the heater core and all the doors and seals are in good shape inside it. I don't think I'm getting outside air in. At least not in any quantity.
Last summer a friend tried to had one of those cheap gauges and he tried to put some r134 in it but it didn't accept much at all; and it didn't work. I've had about as much as I can take. I need some air conditioning. Should I try to flush out the system, install a new filter/dryer, and get a fresh charge of r12? I'm concerned about trying that because the kid at Autozone told me the compressor was for r134.
I'm pretty confident I don't have any leaks in the system.

Here is the issue i am having. 2011 F-350 King ranch with all bells and whistles. In Arizona now we are in the season that the weather is cold in the AM and sometimes hot enough in the late afternoon to need the A/C in the truck. with the settings on Auto which i normally do, and the external temp reading in the 80s, and the internal thermostat set at 70 or lower, the A/C compressor will not engage and allow for cooling the cab of the truck. But sometimes it will work just fine. I am assuming there is a temp sensor for cabin temperature. Where that is located. or will i have to change out the entire Climate Control Module. I would take it in to have it checked out but it is an intermittent problem, and i cant not have my truck for a couple of days while they try and figure it out.

My daughter has a 02 stang with the 3.8 . the other day she complained that her ac was not cooling so i put my gauges on it and checked the freon. the compressor was on and the low side showed about 35 and high side was about 225. it was cooling good, now today it was not cooling at all and the compressor was not on so i jumped the pressure switch on the dryer and it came on, pulled the jumper and plugged it back in and compressor came back on and started cooling. I might have a bad pressure switch also about the pressures could the orfice tube be getting stopped up. this car must have had ac problems before with the previous owner because someone has wired the ac clutch 12v+ wire to the outlet side of the pressure switch and the 12v- side to a ground screw.

Have and intermittent condition with my 1996 F-150 4.9. AC runs and then cuts out (compressor not turning). I lose 12v to both side of high side switch. I tried to troubleshoot using a schematic in Haynes Foprd Pickups and Bronco for 92 and later F-Series/Bronco, but the color code for the wiring doesn't match up.
On my truck, there is 2 wires from the low side pressure switch which mates to a socket with only 1 wire. I have 12 volts at switch terminal on dash control, and it seems that I have an broken wire behind the dash, as I can get it to operate again when I move the harness around. Where can I get a schematic of this part of the circuit?

03 Santa Fe, 2.7 L engine. No cooling happening. Compressor not running. Jumpered both sides of the triple pressure switch. Jumpering Low/high side resulted in slight increase in engine rpm, Jumpering medium side and something turned on (didn't get a chance to investigate) but still no clutch operation on compressor. Wondering what to try next other than disconnecting and dropping compressor ?? Checked AC relay on the bench and the coil operates and contacts close, so that's good. Also10A fuse before relay contacts is OK.

I have an 05 Prius with 53k miles and the ac just recently stopped working. The blower fan still comes on, but neither the compressor nor condenser cooling fan will come on. I've checked the fuses and relays, and they check out ok. I'm hoping there may be one I missed? It just stopped working with no warning signs. What could be causing this? If the compressor was bad, the condenser fan would still work, right? I'm fearing it's the ac inverter. Do the symptoms match?

We have a 2003 Nissan frontier pickup (automatic).The AC recently stopped cooling, but the fan works. It was cooling perfectly great when all of a sudden, it stopped. If we turn the AC on, the compressor (I'm guessing) starts to click and continues to click until turned off. (started to grind under hood). It's not a rattle, definitely a click as if it wants to turn on but can't make the electrical connection. It kind of sounds like when a starter has gone bad and it clicks. Except, it does it repetitively until turned off. This doesn't happen if we turn on the fan but leave the AC off. Does it sound like the compressor went out? How can we troubleshoot it?

I have a 98 Grand am with the 2.5 and recently noticed first that the a/c compressor wasn't coming on. It had freon added recently and did okay for a few days,then no compressor coming on again. (It still has freon) Then I noticed that the engine cooling fan was running as long as the engine is running on cold or hot engine with heat controls off (I know the compressor runs when on on defrost position as well as a/c). I thought the 2 problems may be related? I found 5 relays at R/F strut tower and the 3rd relay cut off the fan,so I swapped some of the relays, but made no difference.The fan only quits when I turn the engine off, and I can't get the a/c compressor to come. I don't if I have 2 seperate problems or not. Could it be the PCM?

The issue I'm having is the A/C. When I got the truck the A/C was completely freezing. Recently however, the compressor was having issues not engaging and I fixed that by simply plugging the cord to the accumulator thing. . Now the compressor engages, but is not cooling really at all. It is an old truck and the compressor is a little worn from what I see maybe 2mm space when not engaged. I checked the levels of freon/coolant with a gauge and the amount is perfectly fine. Plus there seems to be no leaks.
