My HVAC blower is staying on even though the car is off, & i have read other posts on this site & other cadillac forums that points to the blower control module being bad. The thing is the people who had this problem had cadillacs in the 90's & newer, i know things are similar for cadillacs in the 90's, so i want to know if mine has a blower control module & where is it located? Any help is appreciated.

 

Yes, blower power control module is located on top of blower housing in engine compartment.

 

thanks so much for the info. I found it immediately following your description. Too bad its kind of an expensive part, but that is the luxury of owning a cadillac.
