Air Conditioning problem
1988 Cadillac Deville V8 Front Wheel Drive Automatic
I shut off my 1988 Cadillac Deville and noticed that the AC/Heater blower motor continued to run. This continued for some time, and I realized that it was not going to shut off. I finally disconnected the negative battery cable to keep from running down my battery. What would cause the blower motor to continue to run?
