About 90% of the time, The A/C light doesn't come on and the compressor will not engage. When i push the ac button, the fan comes on, but no compressor or light. at random times when im driving or if it is cooler, everything works and the light is on. there are times when the light blinks a few times and stay on or turn off. i have the 3.5 engine and refrigerant level is good.
we checked.....the fuses, all of the wires from the instrument panel, and the grounds from the cluster connection to the fuses and all seemed to be normal. We couldn't find the main master ground, but all of the wires from the cluster seemed to be grounded correctly. We think the problem has to be the custer going bad. it has 126000 miles on the instrument panel. We have another ordered, but only because that is the last resort to fixing the problem. I know it is a weird temp fix, but my husband found a mild tap on top seems to jolt it just enough to make it start working again for a short while until the new cluster arrives.
SOURCE: a/c compressors works fine most of the time at
try to jump the low pressure switch, and monitoryour pressures with a gauge, if everything looks normal, try a new switch
SOURCE: 2001 Olds Intrigue a/c compressor cycles on and
may have bad switch or bad connection at swith.start there first.
