Hey there guys, i just bought about 2 months ago an A4 2009 with 40k on it its in mint condition the only this is that the AC only worked once which was close to the date that i bought the car but i never turned it on again, i went back to the used sales guy and they checked if the compressor and if it had gas, and everything is ok so they plugged it to a computer to see whats wrong, i dont know the code but i have to go back so an electrician can see it,

Any ideas on what this could be before i go back to the used car dealer? i press the AC button but nothing happens, just comes out normal hot air.

 

Check if the compressor wiring got disconnected
