Control Module Cooling Fan

A Control Module Cooling Fan is located inside of the front lower section of the Control Module Box (2). See Figure . The Cooling Fan is wired to the BCM and is switched on when the ignition is On. The Cooling Fan is attached to a duct which pulls cabin temperature air from the passenger compartment and circulates it into the Control Module Box in order to decrease the heat that may be generated by the Powertrain Control Module (PCM), the BCM, and the Relay Control Module.
