The blower motor is the fan that pushes heated or cooled air through dashboard vents.

The blower motor resistor adjusts the amount of current going to the blower motor based on the selected fan speed.

If your fan doesn’t work, check fuses for the motor to make sure they’re still good. Many vehicles have two fuses for the blower motor, one in the interior fuse block and the other under the hood. The blower motor is usually under the dashboard on the passenger side.

Blower motors that make loud squeaks or rattling noises may be worn out and on the verge of needing replacement, however, those noises may be caused by leaves or other debris that can be cleaned out after the motor is removed from the vehicle.

BLOWER MOTOR RESISTOR = Changing the fan speed on your vehicles ventilation system is the job of the blower motor resistor. This simple component varies the amount of electric current that reaches the blower motor, resulting in faster or slower fan speed.

Like many electrical devises, a blower motor resistor generates a lot of heat in managing current flow. As components age, resistance builds up in the system from corrosion in the wiring connectors as well as from normal wear and contamination in the motor itself. Even a clogged cabin air filter can cause excess strain on the ventilation fan. Too much resistance can lead to the resistor or the wiring harness overheating, leaving you with an inoperable fan motor and no air flow. We offer this direct replacement fix for your resistor wiring harness that has been damaged by heat. Save time and money!
