On my 2002 Ford ZX2 my a/c and heater and radio all stopped working when I drive a little air cone through, I have been told its my relay switch but I don't know where that is located, so if any one can help please?!
A/C stopped working? on 2002 Ford Escort
It is more likely a blower switch or similar. The relays on that model are in the black box. If the compressor is working and little or no air flow, look at switches and/or control heads.
