Cadillac Repair: 1991 Cadillac Deville V8, battery cables, cadillac deville


Question
Hello,
I appreciate this help.  My problem is that the blower is staying on constantly.  It continues blowing air through the dash board vents, even when the car is turned off and not running.  The only way I have been able to stop it from running and blowing air is to disconnect the battery cables. When I reconnect the cables the blowing instantly begins again. Please, Any suggestion are appreciated, Thank you!

Hi Jeremy,

       When that happens the blower motor uses too many amps to turn and it damages the power module...in your case shorting it out. It is located on top of the blower motor housing near the passenger side wiper arm under the hood. The fix is to replace the blower motor and power module. Bill
