OPERATION
The Radiator Cooling Fan is designed to keep the cooling system operating at a set temperature. The cooling fan operates when the engine coolant temperature exceeds 106 degrees Celsius or when the A/C has been requested on. The Powertrain Control Module sends an input to the Radiator Fan Control Module to activate the cooling fan. The Radiator Fan Control Module receives voltage from Fuse 2 (50 amp) in the Engine Fuse Block. The Radiator Fan Control Module is grounded through G100.
