I checked the fan it runs, I replaced the temp sensior, I replaced the relay fan still will not run any ideals what could be the problem.
radiator fan does not run on 1992 Buick Century
You will need to check for power to the fan relay. You can also jump the relay to see if the fan motor will operate. You will need a wiring diagram to do this. Please check the repair information available form AutoZone - www.autozone.com, they may have the diagram you need.
