Air Conditioning problem
1994 Geo Prizm 4 cyl Front Wheel Drive Automatic 141000 miles
I got a can of R134a with the hose& gauge (Arctic Freeze) and I would like to recharge the A/C on my car. The A/C is working but not cooling as it should. It is a 16 year old car, I do not think it has ever got a recharge. It blows cool air but not enough, not real cold.
How do I recharge the system? What should I be careful about while doing it?
