Compressor will not turn. applied 12v to compressor and engaged clutch. System cools fine is there not enough freon?
Back by the firewall on the passenger side of the truck, the accumulator has a two wire plug and pressure sensor. If you jump remove the plug and jump the two points while the ac is set to on and the engine is running. Check to see if the compressor kicks off. If it runs then you have either low freon or a bad sensor.
Best bet is to recharge the system, and check your fuse blocks. You can purchase a recharge kit for approx. $30. Ensure that your fuses are good, and check the wiring for a short.
