I haven't been on in a while because I really haven't had many issues with my H3.
However, it got warm this weekend and I went to crank up the A/C and it still isn't working.
I'm getting 90psi on the low side and 150psi on the high side static pressure.
When I jump the relay, I'm getting 35psi low side and 125 on the high side.
Frustrated, I went to my buddy who has a gm scanner and we pulled the following grocery list of codes:
C0240
P0532
P2101
P1516
P1545
P2101
Needless to say, I was pretty pissed that all of this was going on and the dummy light wasn't on in the instrument cluster.
I pulled the throttle body and cleaned it, cleaned all connectors with electrical cleaning spray and got everything but the 1545 and 532 to go away.
1545 is air conditioner clutch relay control circuit
532 is low refrigerant pressure
I replaced the pressure switch and it's still throwing the codes.
Can anyone think of anything that would throw 1545 and 532 together?
Relays and fuses are all good and we can't pin point it with the gm scanner and I'm about tired of chasing this around.
