yesterday my ac/heater stopped working. nothing comes on no air nothing. i checked all the fuses and none are blown. i checked the belts and none are broken. any suggestions.

 

Heater blower motor?
Turn on the key and fan switch to High, then reach up under the glove box and thump on the bottom of the motor. [Caveman test]
if the motor trys to run it means the motor brushes are worn out and the motor needs replaced
