Ford A/C :: When Air Is Turned On Compressor Cycles On And Off
Jul 8, 2009
I just picked up a 97 F350 with a 460. When the air is turned on, the compressor cycles on and off. It only stays on for two, maybe three seconds, then is off for about fifteen seconds. I have one of those of those hokey gauges on the refill can, and it says the pressure jumps when the compressor comes on. Could it be going out on a hi head pressure kinda thing? Could the orifice be clogged? I'll have the freon pulled out, then can get into it....

In my 08 Expedition I notice the a/c compressor cycles on for 18-25 sec. then off for about the same. This is with an ambient temp of about 75f. A/C seems to be blowing cool air-never was really cold since new. The idle drops/surges a bit when the a/c kicks on also-which is what grabbed my attention. Is this a normal or is it short cycling?

2000 Explorer Sport with 4.0L SOHC engine. When I turn on the A/C the clutch on the compressor cycles off and on every 10-15 seconds. The A/C cools and the gas charge is checked as OK. Is this normal?

The ac compressor on my 2003 vue cycles rather quickly after operating for several minutes. The ac blows cold inside and stays cold. When I first turn on the ac, the ac compressor stays running while the vue cools down but after several minutes of operating the ac compressor begins to cycle a few seconds on and a few seconds off. Seems to me it is cycle too frequently?

Just rescued this 2004 from a driveway death. While checking out a no A/C condition I notice that the A/C compressor cycles on for about 10-15 seconds then stops, does this 4 times and then ends. System shows low pressure but doesn't run long enough to build up any. Need to get the OBD-2 tester on it.

The AC compressor on my 97 Quest cycles off and on way too fast when my defroster's on. I know the AC is supposed to dehumidify the incoming air - but it shouldn't be this rapid. Is there a way to control this or shut off the AC when the defroster's on ? 97 Nissan Quest..

When ever the car stops at a traffic light or stop sign, the air compressor cycles rapidly and the cool air turns warm. I was told the cooling fan was not coming on, but the other day the fan was cycling and the cool air stayed cool. My question is what controls the cooling fan operation? It seems the high pressure switch is working correctly and the fan motor is working. As long as I'm driving the air is cool.

I have a 2004 Honda Element and when the AC compressor cycles on it makes a high pitched noise similar to a drive belt slipping. The AC is still cold and the noise is not overwhelming (yet). I know this vehicle has a serpentine belt and that doesn't appear to be making any noise. The only noise is when the compressor is running.
Is there a belt that drives the compressor (other than the serpentine)? And, is this something that I should get fixed ASAP or can it wait until my next oil change? Meaning, if I wait until the oil change (under 1,800 miles) will hurt anything?

'04 Explorer with 4.6L and manual a/c - when turned to MAX A/C the compressor locks on, but fan speed doesn't increase and the heater water valve actuator doesn't move; not sure if Inside Air position is on. This started yesterday; worked fine 'til then.

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.

I have a 1995 Ford Windstar. When I turn on the air conditioning, the compressor clutch does not engage despite having sufficient refrigerant in the system. Jumping current directly to the compressor clutch will engage the clutch, so it's not the clutch. I suspect the relay for the compressor clutch inside the CCRM may be bad, but am not sure how to test it. I have a Haynes repair manual, but how to test this device?

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.

I've had my Subaru for 8 yrs and never had a problem with the A/C, even in 100+ degrees of Arizona. I always had to turn down the temp. I've been in Maryland for nearly 4 yrs and it's worked fine even on very hot and humid days. In March I noticed that it didn't seem as cold as usual. I also didn't hear the compressor coming on when I turned it on. Mechanic checked it out and said the compressor was working but it probably just needed freon (I hadn't added any since I bought the car). They added a dye in case there was a leak and said I'd be able to tell in 2 weeks if it was leaking, but that the dye is greasy and might actually fix a leak if it's just due to a dry seal somewhere. They didn't charge me for the freon. (These are honest mechanics. I've been with them for several years and they've had numerous chances to bilk me but never have.)
Couple weeks went by and it seemed okay, though maybe not quite as cold as when I picked it up. Sometimes I'd drive and it would be very cold so I'd think it was fine, but a few minutes or some time later I'd know for sure it wasn't right. The weather vacillated between hot and cold too, which made it harder to tell. Finally the past 2 weeks it got really hot and I knew for certain it wasn't putting out cold enough air. Yesterday was in the low 90's and I was sick from the heat while driving. Only felt like a fan blowing. I left it at the mechanic's today. They just called and said the vent temp is normal and there are no leaks. They're going to check for an electrical problem, as I also have a brake light that blows on a regular basis. (Though he said those aren't on the same circuit)
As far as my operating behavior, I don't turn it on and off all the time, and once it's going for a few minutes I put in on recirculate. I'm the only driver.

I have recently bought a R32 2008, and when trying to turn the AC I don't hear the AC compressor clutch clicking, the fans are running normally (radiator fans ). What should I check ? Someone told me that maybe it's a compressor problem, and another one said that if the refrigerant gas is low the clutch won't be engaged.

Not sure what happened with my Accent. When I turn on the A/C the blue lights come on, but the compressor is not kicking in and it's blowing warm air. I checked my fuses under the dash and in the engine bay and they look good.

Decided to put the AC on one day but nothing but warm air, observed compressor didn't cycle. Why this would suddenly occur and why?
Vehicle is a 98 tahoe.

I have a 2000 chevy malibu that has not had a/c the past 2 summers. I'm trying to diagnose what the problem could be. When I start the car and then turn on the a/c by pressing the button in the car nothing seems to happen.
When I went to look at the compressor motor I could see that the clutch is not engage and the middle of the compressor is not turning. What to check without taking to a mechanic??

I am having trouble with my air conditioning system in my 1996 Chevy Lumina. When I turn on the AC, the compressor clutch does not engage and the fans do not spin. I was able to jump the compressor so the clutch engaged, however, the fans still did not spin and the AC was not cold. I then jumped the low pressure cycling switch (near the accumulator), which caused the fans to spin while the compressor was running. However, this still did not produce cold air from the AC and none of the AC lines were cold to the touch. I am starting to think the system is low on Freon, but I do not have gauges to test the pressure.

I need to change the AC relay. What is the location of the relay.

The clutch is on 2 seconds and off 2 seconds, and there is a click up on top that clicks every 2 seconds ?..........no cold air either.

I have a 2002 Ford Explorer with AC that is not cooling. The AC clutch engages, then cycles off and repeats the process over and over. With a gauge on the low side port, the pressure rises to around 65 psi when the compressor is off, then drops in seconds down to nearly 10 psi. Does this indicate low AC pressure? I have always seen the pressure pretty much stay static at a certain pressure....haven't ever seen it fluctuate like that from low to high as the compressor kicks in and out.
