get in my car today and turn up the air and it just kept blowing warm air. the compressor clutch aint spinning, i dont hear it nor see it spin. is there a way to test if its in the wiring or the realy for the compressor? what could be the problem? could i need a recharge on refrigerant (that wouldent affect the compressor from spinning or would it) also where is the low pressure side is it the big valve by the rad cap or the smaller one above passenger side valve cover? thanks in advance

anyone

 

The low pressure side is the samll one. on Jumping it over there is a sesnor on the line by the PS resivor if I remeber right. put a jumper wire in it if it kicks on its most likely low on R134A.Dont run it like that for a long time just use it to test it.
