Cadillac Repair: 1995 Cadillac STS, Phoenix Forensic automotive expert

Question
My heater motor does not even turn on on my STS and there is not heater motor fuse in the trunk or under the hood where else might the fuse be for the heater motor. I am hoping it is not the switch.  Tom

Hello,

Unfortuanately you are going to have to take the car to a service center for diagnoses. The heater blower in this vehicle I believe is controlled by the BCM (body control module also known as the computer for the car). You do not have to go to the dealer and pay their outlandish prices, but you need to have a complete diagnostic performed before you change parts without results.
