Question
My grandmothers 93 Cadillac Coupe DeVille AC/heater fan motor continues to run after car is turned off.  Please help.  I can't drive her to the doctor, shopping and beauty shop all time.

Answer
Replace the blower motor that is inserted into the big black plastic housing on the passengers side of the engine compartment and replace the POWER MODULE which is located above the blower motor about 5" to the left of the blower motor and is inserted in the top of the big plastic housing.
