A friend of mine at work has a 98 S10. The AC doesnt work, compressor wont kick on. I am assuming there is a leak. I was gonna get a few cans of 134a and charge it for her. Is this a fairly easy process? I've never had to do one of these before. Any thoughts of wisdom?
well if her compressor won;t kick on, then its not lack of refregrant, look for a loose connection or mabey she has a bad ac clutch, Recharging the system is fairley easy as long as you have some common sence.
Admittantly i am not that familar with GM products, as you might have guessed i'm a Toyota man myself. However, on most AC systems i've seen, they have a low pressure switch. If the refrigerant charge isnt what it should be, then the switch opens shutting off the compressor to prevent damage. Doesnt GM use something like this?
