6gunn Posted August 19, 2004 Report Share Posted August 19, 2004 I have a 1992 Seville that the AC- heater blower motor runs with the car off. I've come out of the house 15 minutes after turning the car off and the blower motor is running, and stays running for about 10 minutes. Anyone had this happen in their Cadi, and know how to fix it?

Willie Hank Posted August 19, 2004 Report Share Posted August 19, 2004 You need a blower controle module, more than likely. It is a 5-sided module (about 5" long), facing down in your blower duct, in front of your firewall, about in the middle. It has a fairly large electrical connector coming out of the tope of it. Its about $ 160 from a dealer, try finding the part number and sourcing from GMpartsdirect.com, to save some money. I pulled the fuse, to cut it out whilst getting the replacement part.

TDK Posted August 19, 2004 Report Share Posted August 19, 2004 This might be a normal condition to clear out moisture after the A/C has operated (assuming it shuts off OK after a while). You may want to search on "afterblow", the following is one topic that came up with a lot or information. http://caddyinfo.ipbhost.com/index.php?sho...58&hl=afterblow Good Luck ! Add power to leave problems behind. Most braking is just - poor planning. Link to comment Share on other sites More sharing options...
KHE Posted August 19, 2004 Report Share Posted August 19, 2004 The afterblow feature was not available in '92. I would tend to lean toward a blower control module. Kevin '93 Fleetwood Brougham '05 Deville '04 Deville 2013 Silverado Z71 Link to comment Share on other sites More sharing options...
6gunn Posted August 19, 2004 Author Report Share Posted August 19, 2004 Well here's another interesting thing about this, if you put the key in the ignition and turn it without starting the car, the fan goes right off. Link to comment Share on other sites More sharing options...
