Engine Cooling problem
2003 Chevy Impala 6 cyl

'03 Chevy Impala w/ 3.4L. Radiator fan doesn't work. BCM has been replaced. The computer can turn on the fan if it bypasses the BCM. Is there a relay or sensor that needs to be replaced?

First check fuses. If OK check fan control relays ( 3 of them, all on bottom side of underhood electrical center). If OK as well then engine coolant temp. Sensor is probably faulty.
