: Need help 86 Deville Cooling Problem

03-26-05, 06:02 PM
My old caddy has a problem. The cooling fan warning light comes on after ruuning the car for several minutes then goes off (during call for heat) cycles on and off (durning call for A/C. I have changed the t-stat and temp sensor and radiator cap. The radiator fans seem to run continuously even when you first start the car after being off overnight. Any thoughts and where are the fans relays located in this car?? Someone else told me it might some problem with fan module???? Ciltons does not detail this fan module or where one might find it or how to check it out????? It is a 1986 Deville FWD with a 4.1 engine. Any help would be most apprieciated :banghead:
