Bruce Nunnally Posted October 21, 2018 Report Share Posted October 21, 2018 Hi Timt, Welcome. Your battery is draining over night? What year and model of Cadillac with which engine? Any other symptoms? Any aftermarket equipment installed on the Cadillac?

BodybyFisher Posted October 22, 2018 Report Share Posted October 22, 2018 To eliminate the battery, first have it load tested to be sure it's good. Check glove compartment and trunk lights 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...
