I got this car recently after it was in an accident. The car started up and ac blew cold for a few seconds then stopped blowing cold. None of the AC compressor lines were visibly damaged. The car was super low on coolant. So I filled up the coolant. I checked the AC refrigerant and it says it has more than the recommended pressure. So I don't think that it lost refrigerant. I checked what I thought would be the fuses for radiator fan and AC and don't see any blown. Is there a relay or something I should check next? Also, What is this wire for?
