My compressor always has power running to it when the ignition is switched to on. Any ideas on why? Also, any links to the wiring diagram for the AC circuit? Thanks!

is it just always running? or have you actually had a test light on it?

if you have had a test light on it and it does actually show that its always getting juice, the low pressure switch is probably bad.

If you havent had a test light on it, it could be a bad clutch that wont dis-engage
