Not a z, i tried joining a truck forum but i gave up. everyone here is more knowlegable anyway.
Its a 97 chevy 4x4 380000 kms, i changed a transistor in the heat/ ac controls so they work now and i just recharged the system to the correct pressure with some r12a, and it works clutch kicks in and all that.
It still doesnt get very cold at all though, it is definatly cooler than outside but now what it should be ive cleaned the condensor and everything and its got air moving through it so i dont know what else it could be thanks in advance
