Cooling fan 2ctrl ckt malfunction - 2005 Chevrolet Impala LS

Answers :

This could be the module mounted to the fan assembly attached to the radiator, a faulty relay, or a wiring issue. I would first begin by finding the proper relay in the battery junction box located by using the vehicle service manual. Remove the relay and jump the circuit with a 14 guage 30 amp fused wire. If the fan operates then OHM the relay and replace if bad. If the fan does not operate and the relay is good then chances are the fan module/wiring is the culprit.
