So after I filled my ac that one day I used it and it worked perfectly fine. Havent really used it since. Well I used it a few days ago and hot air ( slightly cool ) came out. I played around with it today and when I turned the car off i could hear a very slight hiss and I pin pointed it to under the stearing box. I forced my skinny hand down there and I could feel some sort of connection and it was cold. Very cold. It screws in but heres the thing, how do you fit something in there?? The headers alone make it dam near impossible. Any thoughts guys??
