Electric Cooling Fan Quick Test
NOTE:
On models with A/C, electric cooling fans are also controlled by A/C system. See appropriate article in the A/C & HEATING section.
- Ensure engine is cold. Turn ignition to "ON" position. Fan should not run. If so, check cooling fan relay, radiator fan switch and wiring.
- With ignition on, unplug radiator fan switch. Fan motor should operate. If not, check cooling fan relay, fan motor, engine main relay, fuse, and wiring. Connect radiator fan switch.
