Truck is blowing hot air, compresser is not cylcing, hi and lo tubings are warm. Checked most of the wiring hardnesses except for the compresser which I cant reach. Trying to located the hi/low pressure switch cant find.

 

Buy one of those cheap freon fill kits from local auto parts and try to add freon. Get one with a leak detector because you have a leak. One you start filling the compressor should start cycling and continue to cycle less as it fills up. Or take to a shop and fork out 300.00 to pull a vacuum, fix leak and refill.
