ac/ heater problem: i already serched for similar topics.

i have a 91 hatchback, and when i got it every thing was fine, but a while ago my ac stopped working, and a few days ago happened again. first of all no air is coming out of the vents and when ac/heater is off my radio play but when i turn on the ac/heater it goes off. what could be the problem? i have already checked all the fuses and relay and those are ok, my battery is fine and i cleaned out the connectors to make sure there is a good connection. im thinking it might be the blower motorr thats out, but that wouldnt explain the radio going out. sound off please, i really need to fix it soon cuz its a pain in the *** when your car fogs up all the time.

Check for voltage and ground at your blower motor connecter when you turn the switch on. As for your radio if its aftermarket see where you are getting the power from might be your a/c system , hince the combo problem...let me know and ill help you out ..late
