coolnesss Posted June 30, 2009 Report Share Posted June 30, 2009 First, get some WD-40 and spray it into the switch, while you're manipulating it back and forth quickly, for a minute or so - both at the affected window and at the driver's door master control. Sometimes what you're experiencing is oxidation of the contacts, and I've had this treatment clear up the problem several times with older cars.

Logan Posted July 1, 2009 Report Share Posted July 1, 2009 Anytime a GM vehicle of that era...Slam the door shut while holding the up or down on the window switch. 95% of them will start working again.

BodybyFisher Posted July 3, 2009 Report Share Posted July 3, 2009 Take the switch out and test it with an ohm meter in both directions to determine the health of the switch, if you reversed it and it worked this has to be the switch Pre-1995 - DTC codes OBD1 >> 1996 and newer - DTC codes OBD2 >> https://www.obd-codes.com/trouble_codes/gm/obd_codes.htm How to check for codes Caddyinfo How To Technical Archive >> http://www.caddyinfo.com/wordpress/cadillac-how-to-faq/ Cadillac History & Specifications Year by Year http://www.motorera.com/cadillac/index.htm Link to comment Share on other sites More sharing options...
