okay i looked at it and it has plenty of freon. and i checked the the wiring and the relays. i've traced all the wires back to where they go into the firewall.there is no power to the compressor but there is power to the a'/c fan.
I have installed 4 A/C's in the past year into non A/c sidekicks as it is very hot in my neck of the woods, so here are some things I learned.
Have you swapped the relays for the compressor and the fan? that will help you rule out the relay. usually the fan comes on with the compressor. Have you put 12 volts to the compressor wire. it should activate, if not bad clutch.
Second, there is a temperature sensor in the intake manifold that may be open. Take the wire off and put it to ground and everything should work.
Third, if there is no change , and you checked that all the wires are good, you may have to replace the A/C amplifier(computer). I have had the computer go bad on 2 different trackers. In both cases, the circuit for the fan did not go to ground to turn the fan on, but the system should work the same for both the compressor or the fan. I bought one from Trail tough for 45.00 I am sure hawk has em.
