Anyone know where the fuse or relay for the engine ac is located for the 1995 p30 Chevy chassis? I have no power to the compressor or low pressure switch. If I apply 12 volts to the low pressure pigtail the compressor clutch engages and the system cools. The low pressure switch should have 12 volts going to it when the system is energized-Right? I believe there should be a relay or fuse somewhere considering the amps the ac clutch draws.

On our 96 Flair the fuse which powers the dash HVAC controls is under the instrument panel. It is marked 20A Gauges. When the fuse is removed, both the fan blower stops and the a/c clutch disengages.

I'll check that one on mine, the blower is working but the clutch will not engage.

Tomorrow I will have time to check that fuse, but everything else on that circuit works fine. I believe there should be a relay somewhere for the a/c circuit. Do you know where the low pressure a/c cutout switch or the a/c relay is located? My guess is it is under the passenger side of the dash which I wonder how to get to it or wonder why they would put it in such a place that so complicated to get to. Does anybody know if the a/c cutout on the accumulator is a combo high and low pressure sensor?
