What is a fan relay switch?
The function of the cooling fan relay is to convert a low voltage signal from either the electronic control module (ECM) or a thermostatically controlled sensor. The cooling fan relay takes the low voltage signal and internally switches the relay “on” to allow battery voltage to be supplied to the radiator cooling fan.
Why did my oscillating fan stop working?
Each fan uses a motor within the fan’s housing behind the spinning blades. Any moisture within the motor’s mechanical parts can corrode the internal bearings. Corroded bearings will eventually seize, causing fan turning failure for both the oscillating feature and blade movement.

What causes a fan motor to seize?
The main causes of failure are loss of lubricant, a failed run capacitor, a failed bearing in a belt drive, a little water dripping into the windings or a voltage problem. So technicians should carefully check to find the cause of a failure before changing the motor.
Can I use WD40 on fan motor?
WD-40 can be used to clean the gunk out of a fan’s bearings, but it MUST be removed and replaced with a proper lubricant.
