BodybyFisher Posted February 6, 2011 Report Share Posted February 6, 2011 Have you checked for possible DTC codes that have been set? The cooling fans and the coolant temp sensor can set codes. There is also a fuse that protects the cooling fan circuit. At the bottom of this posting is a link to checking the DTC codes, click it and follow directions to your year to see if codes are set The coolant temp sensor is screwed into the rear head on the driver side down below the EGR valve, see this diagram 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...
