Ford - Explorer :: 2001 - Compressor Not Cycling
I thought originally I had a leak so I tested with dual gauges I'm getting 85 psi on low and high side, which I believe is good. So I tried grounding the low sensor, then high sensor, then both, then both just pulled out and any combo possible. Still not engaging. Switched out the relay, checked fuses, still not engaging. Tried taking shim out of compressor still nothing. Jumped the relay and it will engage and air comes out cold. What should I check next?

Compressor seems to cycle to frequently, every 5 Seconds. Morning and Night the ac is freezing. During the Day it's cool but not cold.
Hooked up gauges and the high side is around 150 and the low side will go up to 45 and drop to 25 ( this is when the compressor engages and disengages.)
Ambient temp is just under 80. Where to go from here? 2003 Sport Trac...
Ford A/C :: 1989 F350 - Compressor Cycling On And Off
I purchased an 89 F350 460 EFI factory air. The air worked fine for the first 6 hour on the drive home then It just stopped blowing cold. When I got home I saw the air gap on the clutch was quite wide so I took the washers out, still was too wide. I could only get the clutch to pull in if I tapped it in by hand and it only stayed in for a short time. This was all last fall.
Today I replaced the clutch, compressor and drier, took it in and had it charged. They replaced the pressure switch because the compressor cycle on and off. Even after replacing the switch it still cycles on and off and I still have no air! They removed some of the charge but still no air. The clutch pulls in and runs for 2 sec every 15- 20 seconds. I assume the reason it cycles is a high pressure. What should I be looking at now?????
Ford A/C :: 2002 F250 - Compressor Clutch Not Cycling
I have a 2002 F250 on which the AC compressor clutch is not cycling: I have checked and added coolant so low pressure is correct (don't have high pressure gauge). I checked the clutch air gap and it is at 0.030 " as specified in another post. I replaced the low pressure AC cycling switch (on the evaporator/dryer). With the AC on, I disconnected the AC cutoff switch and the clutch disengages. This circuit has the correct (>10V) going to it. I am thinking it could have something to do with the AC relay.
When you switch the ATC to a setting other than AC or Max AC, the clutch disengages fine. I noticed this problem because the AC shuts off when it is really hot, after I have been driving for a long while, about 1 hour or more. If you shut off AC, wait a few minutes, then turn on it works fine.
Ford F-150 - 1997-2003 :: AC Compressor Not Cycling After Replaced
My AC compressor failed so I replaced it.
I put in 1 can of R134, and I don't see the compressor cycling.
How do I remove the connector to the accumulator so I can jump it and force the AC to run.
Ford - Explorer :: 1996 - AC Compressor Clutch Was Cycling On And Off
He has a 96 explorer and his ac compressor clutch was cycling on and off. So he went and bought 2 20 ounce cans of 134a and proceeded to add it to the evaporator service port. Of course a lot of it sprayed out side of it as it did not fit well (duh). So he has no Idea how much he actually got in there out of the 30 or so ounces he dispensed. He is laughing at himself with me on this. He says hi ahead of time
I have access to good gauges and a reclaimer and vacuum as I work sometimes for a residential ac guru. So what to do? I was thinking the evaporator should be changed out but I want a second opinion. Then vacuum and add new 134.
Ford Expedition :: 2003 - A/C Quit Working - Compressor Cycling On And Off
My 03 Expedition A/C quit working, the compressor was cycling on and off so I took it in to be recharged thinking it was low. They said was completely out and it took 3.5lbs to recharge although they couldn't find any signs of leaking. When they recharged it they put more dye in to find the leak, the technician said he suspected a compressor since it was completely empty and had been working in the spring.
I was hoping it was a compressor as I have changed one before on my 97 Expedition and am pretty comfortable with it, however I can't see any thing leaking using a UV light. I have checked the compressor and every line I can see all the way back to the rear (it has rear air). When they recharged it worked very good for about 8 days on the 9th day it was working and went from blowing cold to hot instantly. Where or what to look for??
Ford F-150 - 1997-2003 :: Compressor Cycling Even When AC Or Defroster Is Not Turned On
My 2003 F150's compressor cycles even when the a/c or defroster is not turned on. It has the climate control type of temperature system. This doesn't seem normal.

So again the a/c in old green gave out. it has been an ongoing battle over the past few years, but this time I took it to a good friend who has all the right tools as our level of frustration dealing with it has peaked.
We removed everything, and got it all "new" from oh-rye-lees. a new compressor was installed a few weeks back and it worked fine, but cycled very strangely. it would rapidly kick in and out, then just stay engaged. found out the condenser was plugged up and thought maybe that was causing it.
At any rate, it now has a new compressor, condenser, evaporator, drier, orifice tube, and low pressure switch. all the lines were flushed and checked.
it was vacuumed and checked, then charged with freon. The compressor is doing the exact same thing! it is cycling very strange. sometimes rapidly at higher rpm, and sometimes it works just fine. the a/c is working, but it is freezing up the drier, evaporator, and line all the way back to the compressor. vent temps are about 30.
The WOT relay and high pressure switch was replaced, and it did not make a difference. we are at a total loss.
We were told by another person that the clutch on the new compressor was too small and that was causing the issue. It measure 4.8" and we were told is is supposed to be 5.3". is there any truth to that? we just do not know what is causing this, but want to get it right as surely something will break if it stays this way.
Ford 6.0L Power Stroke Diesel :: Compressor Cycling But AC Not Blowing Cold At All
So my Ac is not blowing cold at all. I can hear the compressor cycling. I filled the sys with freon. Still not cold I am pretty sure I have a leak but wouldn't it still blow cold? What do I need to check to fix this? The temps are getting in the upper 90's and 100 s I need Ac bad...

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?
Ford A/C :: 1997 Expedition - Compressor Is Short Cycling Real Fast / Warm In Front And Cool Air In The Back
I have a 97 expedition that i am having trouble with. It has front and back airconditioner. The compressor is short cycling real fast. Warm air in the front and cool air in the back. I put a can of freon in but still not cooling. The gauges are between 30 psi and 50 on the low side. The high side is between 100 and 150 psi. The ambient temp was 80 degrees.....

2009 Accent with 103K miles, which has been good to me so far. Over the past week or so, I've noticed that when I'm driving on the highway with the A/C on, the car occasionally hesitates, maybe every minute or two. I'm guessing this is from the A/C compressor cycling on and off, but it's never done this before. Does it seem like this is the beginning of the end for the compressor? Anything else it could be?
View 1 RepliesFord Super Duty (1999-2016) :: A/C Clutch Staying Engaged - Compressor Burned
I 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?
Ford F-150 - 1997-2003 :: Compressor Still Engaged When Temp Control Switch Turned To Warm
1997 F150... What part of the control system tells the compressor to turn on and off? After not having air conditioning for a year or more I replaced the broken blend door.
When the a/c is turned on and the temp control switch is turned to cold, I get cold air. When I turn the temp control switch to warm, the air coming out of the vents is very warm. However when I do this I noticed that the compressor is still engaged. I think that at this point the compressor should disengage.
Camry :: 2008 - AC Compressor Stuck Engaged
I think the ac compressor on my wife's 2008 Camry (2.4L) is stuck engaged. I've pulled the wire and it still didn't come loose. That being said, I've also read about a Mercedes that doesn't have an ac clutch, but rather the compressor vanes are varied to increase/decrease the compressor pressure. It's a shot in the dark, but perhaps it's the same with the Camry? It's been this way all summer (that I know of). The A/C seems to cycle on and off properly within the cabin. If it weren't for possible increased fuel consumption, extra drag on the motor, and possible premature component failure I wouldn't even be concerned with it. What to do with this?

View 3 RepliesPontiac - Grandprix :: Compressor Is Engaged Whether AC Button Is Pushed On Or Off
1999 grand prix. Controls are manual version, not automatic climate control. a/c works fine but compressor is engaged whether a/c button is pushed on or off. the only way i can disable a/c is too set fan speed to OFF. does not matter if control is set to vent, or feet. a/c runs with a/c switch set to on or off. This is not an issue of selector set to dash or defrost. I assume it is not a clutch gap issue since the compressor shuts off if i turn fan control to OFF.
