SOURCE: ac compressor clutch does not engage

to prevent damage to the air conditioning system there is a "low pressure switch" located on the condenser near the low pressure hose (large one) .. if the refrigerrant (R134A) gets too low then the clutch will be blocked from activating by that switch .. you can have your system tested and recharged or you can do that yourself .. the R134A is available at auto parts stores .. some come with a gague that is required for proper charge .. if you dont already have a gage then yoiu will need that one ... recharge kits often come with instructions .. other less likely but possible problems could be a fuse or bad AC clutch relay. sometimes damaged wiring or bad clutch will be the problem but much more likely just low fluid ..

SOURCE: on 2002 buick regal ac problems. Tried a jumper

Does the system have a leak? If it does, then the computer might have set a low freon code that usually does not turn on the check engine light by itself. If this occurs, the code will have to be erased before the compressor will run. The computer does this in order to protect the compressor so that it cannot run without enough freon in the system. Once you correct the amount of freon in the system (if it needs it), reset the system and see if the compressor will run. Some parts stores have the ability to erase codes and will usually do it for free. I hope this solves your problem. It's definitely not good to have AC problems this time of year. Thanks for trying Fixya.com.

SOURCE: I just replaced my ac compressor on my 1995 Dodge

ABSOLUTELY!!! And if you are trying to run the compressor WITHOUT freon, it is a very good way to destroy a new compressor!

Does ac clutch gap causes ac clutch always engaging

How to fix ac clutch that always engaging


Hi Mark
Thats an easy one...
It gets told to engage by a single wire attached to the clutch.
This usually has a bullet type connector close by.
12v = ON
Disconnect it. Solenoid disengages.
(you could put a switch in the line)

This wire is controlled by the AC (control electronics) temperature sensor & the pressure build up in the refrigerant lines.
Eg The unit turns on to cool vehicle but the refrigerant is low or the high pressure line is too high so it shuts off. Then the cycle starts all over again.
You need some Service on your AC system.

Cheers

Ac not working right


Your A/C clutch is at fault and it is wearing your belt to get broken! Open the hood, have someone start your engine with out starting your A/C. Check your serpentine belt pulley and tensioner for wear. Then have someone turn A/C on high and watch the cluch engage or disengage. If clutch engages but do not turn you need to get it replaced or repaired.

Compressor and fans do not turn on until rev engine


I passed this question the first time I read it, so I will take a stab at it now.
The fans don't come on until the compressor has pumped the freon pressure up to say 150 or 200 psi. And the compressor clutch has to have voltage to engage the clutch.
I wonder if the clutch is going and needs 14 volts instead of 12 to engage ? Or the relay that powers the clutch ?
Speeding up the engine would increase voltage from the alternator.
This is assuming the serpentine belt is tight and everything else is working correctly.
I think I would swap the relay with another and put a meter on that circuit to the ac clutch to see what it takes to engage it.

AC doesn't blow cold air on 95 4 runner. Can I check compressor


Well, for one with the truck idling, the RPMs should increase every time that the clutch on the compressor engages. You should be able to see it engage and disengage and the RPMs will change accordingly. If this isn't happening then you need to determine why. Have the A/C blower on low when doing this.

AC Compressor


There is a PRESSURE sensor that monitors that amount of pressure in the A/C system and if the pressure gets to LOW the sensor will NOT let the compressor engage.
