Some days ago when I tried to turn on my AC the fan started but the green light indicating the compressor or AC starting stayed off. So i checked all fuses and relays, unplugged and plugged them again an after that the AC started normally, working normally during a couple of days. After that the issue happened again, the AC doesn´t start when I turn on it but later after a while or hours it starts normally. When it starts everything works find, fan , compressor etc works fine. So can somebody help me about this issue? What would I have to do for solving it?. Thanks in advance, My BMW is a 325i 4 doors E36 1993.
