There could be a few reasons why the ac is not working, if you power the compressor it turns on, that means the compressor clutch is working.
The system may be low on freon gas, the next step would be to have a shop hook up to ac system and check gas level. it may be as simple as the system being low. if it is low there may be a leak so have them add dye to the system if it is low.

the system is under pressure caution if you are not ac certified i would not mess with it. adding gas when not needed will cause compressor failure and may even blow hoses, be careful.

I would say the next step would be to check your fuses and then have the freon amount checked, good day

SOURCE: 1992 gmc c1500 ac compressor relay location

I pulled this from another web site
"The AC clutch relay is located inside the cab on a metal bracket that is easiest to see when you remove the glove box compartment.

The relay is on a metal bracket bolted to the top of the plastic air box, forward and to the center of the dash from glove box.

There are three relays in a row on that bracket. The AC clutch relay is the end one closest to the driver’s side."

SOURCE: blows hot air clutch does not engage

you either have a power loss problem but more likley your low on refrigerant. if its low, there is numerous pressure sensors that will not allow it to engauge to protect the compressor. you got to put a gauge on it. standing system at 80"F should have about 80-90 lbs. standing pressure.

SOURCE: AC system, compressor not engaging.

Sounds like your a/c system is low on freon, system has a low pressure switch which disables a/c compr.so that it don't damage a/c compr, it would be kind of like running an engine with on oil it would damage an engine, what needs to be done is have dye injected in to a/c system to be able to fine the leak, once leak is found can be repaired and recharge with freon, system will work good after repair has been done.Good luck

SOURCE: ac compressor clutch is not engaging

Dear Madam or Sir,

this concern is prpbably due to a lack of coolant. There is a pressure sensor monitoring the system pressure of the A/C system that will interrupt the activation of the A/C compressor to prevent it from being damaged.

If there is not enaugh coolant, the system pressure will drop below a fixed threshold level and the compressor protection circuit will activate.

So you should have the coolant level to be checked at the shop, if it´s OK, put an eye on the pressure switch itself :)

My 99 tahoe a/c is not working and is recharged properly. The clutch does not engage on the compressor and the compressor is new. What can the problem be


if you did the recharge then check the gas pressures as there are two main switches that control the ac operation
one is a high pressure switch which stops operation if there is excessive gas or a blockage and the other is a low pressure switch which stops operation if the gas has leaked out
did you have the ac system checked for leaks before gassing it or replacing the ac compressor
lastly some systems have a relay that controls the ac and that can fail

No current to ac compressor


A mechanic would start at the compressor and work back.
Did you jumper the low pressure switch, or the relay, or put power directly to the ac clutch ?
You have a low pressure switch that should be closed and a high pressure switch that should be closed to put power to the compressor clutch. If the freon pressure drops below 20psi the low switch opens, if it goes above 300 psi the high switch opens.

Ac does not engage


Most vehicles have a low pressure switch that prevents the compressor from engaging so as to prevent damage to the compressor. You need to place a gauge set onto your AC to read the high and low sides of the system. Probably have lost enough gas(R134) over time to prevent the compressor from engaging. You can jump the pressure switch to check it with a simple jumper wire.

My a/c compressor is only blowing hot air when I turn it on. I know a little about cars so I know it's the a/c but I am not able to find one on any site that may sell used or new.


If all you get is hot air there are several possibilities. The compressor is driven by the serpentine belt and is engaged and disengaged by an electric clutch mounted on the compressor drive pulley. With the engine running, have an assistant turn on the AC while you observe the AC compressor clutch. If the clutch engages, you can be reasonably sure that the system has freon, and the electric circuit is OK. If the clutch doesn't engage, which is the most likely situation, either you are low on freon, the AC clutch relay is inop, or AC compressor fuse is open (blown). A search of Google images will give you the location of the AC relay. You can pull out the relay, carefully remove the cover, reinsert the relay, and engage the compressor clutch by manually closing the relay contacts. Warning: do this only for a second or two in order to see the clutch engage. If the clutch does engage, then you are probably low on freon. There is a safety switch that prevents the clutch from operating if there is not enough freon in the system. Hopefully, this is the case. Go to Walmart and get two cans of r-134 and the inexpensive kit, and following their instructions, charge your system. If this is not the problem, you'll need a set of AC gauges and the skill to use them. Hope this helps. Dano

A/c has full freon but the compressor clutch wont engage. i have found that the plug going into the compressor is not getting any power. what could be the problem?


On the low pressure line of the ac you have a pressure switch which allows the compressor to come on once a certain pressure is reached, and it will cut the compressor off if the pressure is too high or too low. Look at your ac hose and find the switch *you will see wires connected to it* you may need to replace this switch. You can use a test light to see if you are getting power to the switch. You should check you fuses, and the ac relay witch is usually in a black plastic box under the hood.

After i put the ac on my bmw x5 2003 get over heat and smell burn


pls. check your ac compressor magnetic clutch attached in front of ur compressor if its working/ ac clutch engage when u turn the ac switch on and disengage when u turn the ac switch off/ it normally makes a clacking sound when it engage with the rotation of ur compressor/ if its not engaging it means ur magnetic clutch is stuck up giving excessive load to ur engine thats why it overheats/ it smell burnt because its magnetic coil is fried/ or check cooling system of ur car might be that coolant is empty/ fan is not working/ radiator is clogged or thermostatic valve is stuck blocking coolant flow....

Ac does not work blowing warm air dealer mentioned compressor & receiver out ? is this a current problem with the 2004 ?


Hi,
With engine running, I would check to see if the compressor clutch is engaging when the AC is turned on. If not, I would first have the freon level checked. If after checking, it is fully charged but not engaging, I would then suspect an AC relay switch.
I hope this helps... Good luck!

Have you charged the ac. If so check the low limit sw. on the dryer it will cut the power to the compressor if the charge is low or if the sw. fails.
