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."

you may need to top up the coolant,r112,r140or what ever the car is useing. if the car can'nt be topped up then you have a leak that needs to be fixed,usually the drier.

Pump a jumper in the connector the low pressure compressor cycling switch near the accumulator canister to see if the Compressor engages. See picture of switch below, it is in the low pressure line or the accumulator.

How do I get fire to an AC compressor I just replaced on an 2001 Chevy Z-71 5.3?


Did you fill the system with refrigerant? That system should take 1.8 pounds. Next place to check is the low pressure cycling switch. It's the switch on the accumulator (big round silver thing on the fire wall on the passenger side).

Good luck.

Ac clutch not kicking on


ADD Freon. It's a R134 system and the pressure is too low. Trust me add Freon and it will work fine. With a low amount of Freon if you jump the low pressure switch at the accumulator it will be very cold but will not have enough pressure to kick on the low pressure switch.

Ac not working not a fuse or relay ?


The accumulator or dryer looks like a long cylinder, it has a pressure switch on it and two wires attached to it. pull the wired molex off, with the ac set on max cooling, jump out the two wires with a wire or paperclip, if the clutch on the ac compressor engages, check the cab to see if its cooling, if it does cool the switch needs to be replaced, if it does not cool, you may need freon, and there could be a sign of a leak in your system, that can be best checked with ac manifold guages. the low pressure switch is there for safety if the canistor or accumulator is low or has no freon the switch opens up and keeps the clutch from running so that the compressor will not burn up. good luck!

My husbands 93 park ave ac compressor is not running, when he relplaced the ac relay it worked one time and then no longer works. There doesn't seem to be any power getting to the compressor, could there...


If it has the auto air functions.On the passenger side under glovebox remove the black cover under the dash and there is a hidden fuse block with a ac fuse. Check for this a very common issue. Also if the ac is fully charged you can unplug the low pressure switch located on the accumulator( silver canister located by the relays towards the firewall) and take a wire and place between the two terminals just make sure the compressor will does come on.If the ac is turned on and you jump that switch and the compressor does turn and ac starts working then a good possibilty that the low pressure may be bad. Would check the fuse first.

2001 chev tahoe has no power at a/c clutch checked fuses,relay,high pressure switch,low pressure switch and has 100 lbs of pressure on low side port


IF YOU HAVE 100 PSI ON LOW SIDE.YOU HAVE A EXCESSIVE AIR AND MOISTURE IN THE SYSTEM.YOU HAVE TO HAVE SYSTEM DISCHARGED AT AC SHOP OR DEALERSHIP.YOU HAVE TO REPLACE ACCUMULATOR OR RECEIVER DRIER.HAVE SYSTEM EVACUATE.THEN RECHARGED.SEE YOUR AC IS NOT TO COME ON LONG AS YOUR LOW SIDE TO HIGH.YOUR LOW PRESSURE SWITCH. IS NOT GOING TO CLOSE CIRCUIT TO TURN ON COMPRESSOR.UNTIL PRESSURE DROP AT A CERTAIN LOW PRESSURE.

A/C Compressor not kicking on


The power to run the compressor clutch coil goes from the battery, to the AC Clutch Relay, somewere in the engine compartment fuse box, then it goes to the positive side of the AC compressor clutch coil; goes thru the coil, activating the compressor, and then goes to complete the circuit through another switch (high pressure protection switch) in the back of the AC compressor and finally reaching negative or Ground.

Disconnect the AC compressor clutch connector and using a 12 V bulb with 2 wires (test lamp) check the following:

1.- connect 1 lamp wire to battery neg; with the other check both pins at connector with the AC in the RUN (AC and ignition switch on ) you should have power in one side.

2.- connect 1 lamp wire to battery positive and with the other check both pins at connector, lamp should light getting the ground from the clutch connector thru the high pressure compressor switch to ground.

On the other side what makes the relay close and let the power flow to the clutch works with the low pressure switch, (if the freon pressure is too low it opens and kills the ground to the relay coil and that kills the compressor), that low pressure switch is in the low pressure side of the freon tubing, the fat pipe that comes from inside the firewall into the accumulator/dryer, a big aluminum cylinder sitting on the right side of the engine compartment in GM cars.

To know if the low press switch is the cause you can unplug it and connect both legs with a paper clip for a minute or two, no more, you don't want to damage the compressor. anyway if jumping the switch makes the compressor come alive and kick in, you either have low freon pressure or a bad switch; it's time for the pressure gauges and check how the compressor is pumping and that is better left to a pro.

By the way you said that your system is a R-12 system, have you considered switching to R-134a the new "ozone friendly" freon? to do that you need to evacuate the system with a recycling machine and pull vacuum in your AC, if it holds the vacuum for a while, then you can be sure that there are not leaks and then dump 1.5 or 2 pound (check the labels in the engine compartment) of R-134a into your system. it will be a good idea to put some fluorescent leak detecting dye in the system to check for leaks, just in case..

No power for AC compressor


try removing the plug off the low pressure switch on the accumalator plug a paper clip into the plug and turn ac on if it comes on then your low pressure switch is bad or your low on refigerant.
