Question about 1990 Cadillac Deville
I can not shut off my blower motor. I was told that the relay was behind a panel above the moter. I bought a new blower moter relay from GM. when I remove the old relay the motor continues to run. Is there another power source?
This usually indicates failed ECC power module.
The location of ECC is as follows :-
The electronic climate control power module.It is located on the rear fire wall in the engine compartment to the right of the blower motor.here is a diagram,the module is #7 .
Hope i helped you.
