Question about 1998 Chevrolet Cavalier

1 Answer

I have a 1998 GMC Jimmy & there's no power going to my low pressure switch which is located on the accumulator. I ran a hot wire from the battery to the ac compressor, filled the system with 1.8lbs of freon & the low side pressure is exceeding over 60 psi. the system is not cooling & I can't get the system to cycle.

Running a hot wire bypasses any compressor cycling. Low side should pull down to 20 psi or less when compressor is hot wired. If not pulling down you may have weak compressor or way to much freon in system.

No power to key ignition 1998 GMC Jimmy


Look for the inline fuse link in the red wire from the battery . It looks like something was spliced into the wire. It's the fuselink.

Wont turn over. Has power, everything comes on but when you turn ignition to start, it does nothing!


Check the fuses in the main fuse box under the hood. Look for a fuse marked starter or starter relay. The easiest way to get the a/c clutch to engage is to jump the connecter that goes to the low pressure switch, which is located close to the firewall on the larger diameter a/c line.

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.

I have an 1998 GMC jimmy 4.3 motor .my air conditioner quit working so I thought it needed charging .but once I hooked of the canister to refill the aircon I seen the compressor was not turning .so I...


There should be a low pressure switch located on one of the metal a/c lines. It probably has 2 wires. Sometimes it is necessary to 'jump' across this switch to complete the circuit to the compressor until it starts to accept freon and build pressure. This is a safty feature designed to prevent the compressor from locking up due to the absence of oil, which is carried by the freon. Good luck. Dave

Cannot locate where the a/c clutch cycle switch is... there is no power in the wires to the clutch and fuses are okay.


The a/c clutch is attached to the front of your a/c compressor. It is the part that your serpentine belt runs on. It is either engaged or not based on the demand of the a/c system. It will not run if it senses low pressure in the freon supply line so you might try having the system checked for proper fill before replacing the clutch.
