Question about 1994 Buick LeSabre

1 Answer

AC compressor clutch not engaging. Fuses ok pressure switches ok. Ohmed out & jumped Pulled cover for Maxi Fuse / Relay Center. Paper decal that was glued to inside of cover missing. This identifies relay locations. There is a bank of 8 relays from left to right, which one is AC? Suspect bad relay. As you know this is a busy relay even without running AC. Would like to test or replace. Thanks for your time. Rob

Sounds like lack of gas pressure,take it to specialist and and get it recharged to the correct weight of gas,it is positivly dangerous to play with this because the A/C uses high pressures and can cause frostbite in 2 seconds when trying to refill with these boy racer silly aftermarket top up cans.THESE SHOULD BE BANNED WORLDWIDE

    do not attempt to play because you could run the compressor with no gas in it which will result in seizing the compressor ,get it re gassed and it will work

The a/c compressor clutch will not engage even when I jump the low pressure switch thats mounted on the top of the accumulator (dryer). Is there another method such as direct from the battery? There are...

The low pressure switch is just a sense input to the PCM - powertrain control module > Grantit , it is needed for the PCM to know the pressure in the system . But the PCM must energize the compressor clutch relay for the compressor to engage . Finding the compressor clutch relay in the under hood fuse / relay box an testing there would be the best place to start . Pull the relay out of the fuse box , look on the bottom ! You should see four set's of number's ,30 & 87 plus 85 & 86 . 30 & 86 should have B+ voltage . Use a multi-meter to test . 85 goes to pin # 1 connector 3 at the PCM . The PCM supply's a ground here to energize the relay if condition's are right . You could jump pin's 30 & 87 an if the compressor clutch coil is good ,the compressor clutch will engage . Video's on youtube showing how to do these test .

97 chevy suburban AC clutch won't engage pressures

Looks like the low pressure switch gets power from a 10amp ac fuse. Power then goes to the ac relay which is powered on by the ac heat controller on the dash. Power then goes thru the high pressure switch to the compressor. The ac relay is grounded to the body. Do you have power on the lite and dark green wires going into the relay and is it grounded ?

If you do not have enough refrigerant in the system. The low pressure switch will prevent the compressor from engaging to avoid damage.

Check your pressure.

I don't recommend this, but you may need to jump your low pressure switch to get the compressor going to add more refrigerant to the system. But if your low on charge, it may be "best to take it to a shop to have them fill the system".

97 Lumina. No 12V at the AC compressor clutch. Fuses ok and Emron relay ok. Any ideas where to look for an open in the circuit? Thanks Sam

Try checking the low pressure and high pressure switches. If one of these are faulty it can keep compressor from working. Take a paper clip and jump the ports on the plug in for the switches and see if the compressor comes on if it does then that switch is bad.

1996 Buick LeSabre AC Stopped Working

The first thing to check is if there is enough gas. The compressor will not work when the gas is low. There is a small inspection glass on the line. This needs to be clear. If you see streaks or bubbles means the gas is low. Never mind the pressure or wiring for now, Add one can of gas and this should get that first part done.

Cannot find relay center in 1990 corvette

check the low side switch located on the ac receiver drier for 12 volts if so jump it with a paper clip if the compressor comes on then the relay is good if not the relay is in the fuse junction box under the hood.Most likely the pressure sensor.

Ac new and ran for 4 months then stoped.

Try checking the spacing of the clutch of the compressor to your A/C...chances are the gap is too large and will not pull down to engage the compressor. That should eliminate the jump wire and keep your car snowing. No clutch to engage the compressor, no A/C.
