what are the high and low side pressures?

yea prob a low presure switch or something. check for power going to the ac compressor clutch when you try to engage the a/c. If not, then start checking the a/c pressure switches. You can even bypass a switch with a jumper wire to see if that switch is the cause.

I agree with those guys. 90% of the time the compressor goes bad and it locks up. Its defiantly a switch or sensor. :cool:
