Before going out of town last week, I complained to my boyfriend that the air in my 93 Camry wasn't cold. While I was gone, he "surprised" me by adding R134a to the system, even adding on some kind of special fittings that came in a kit. He did not get the freon out first. It blows cold air now, but how long will this last? I hadn't gotten it fixed before because I can't afford the conversion cost at the auto parts place right now. Will this destroy my AC? Is there anything I can do to fix this on the cheap?
Please help!
