Radiator Cooling Fan: Testing and Inspection






ELECTRIC RADIATOR FAN

The powertrain control module (PCM) will enter a diagnostic trouble code (DTC) in memory if it detects a problem in the auxiliary cooling fan relay or circuit. Emissions Control - Description.

If the electric cooling fan is inoperative, check the 15A fuse in the junction block and the 40A fuse in the Power Distribution Center (PDC) with a 12 volt test lamp or DVOM. Refer to the inside of the power distribution center cover for the exact location of the fuse. If fuses are okay, refer to ELECTRICAL SCHEMATICS for the cooling fan and relay circuit schematic.
