Ok. I cant take driving my beater anymore in this horrible So Cal heat. When I turn on my controls (for heat) I get only a small amount of air blowing only out of the defrost. That is problem number 1. any ideas? The ac unit is there on the engine, but I have no lines going anywhere. In theory, if I found replacement lines and hooked it up, I should just be able to charge it with R 134 and it should work, if I could get air into the car. If anyone could tell me how to trouble shoot, it would be greatly appreciated. Jesse
