Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Blower Motor Switch
The blower motor switch controls the blower motor speed and enables the A/C request button. When the blower is set to HI, the blower motor switch provides a direct ground for the blower motor, resulting in HI blower speed. When LO, MED LO or MED HI blower is selected the blower motor switch directs the blower motor ground through the blower motor resistor.
