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 Switch (Rear Blower Front Control Switch)
The rotary Blower Switch has five positions, Rear, Off, Low, Med, and High. The Power Switch must be on to make the Blower switch active. The Blower Switch must be in the Rear Position to make the Rear Blower Rear Control active. Toggling the Power Switch results in the A/C-Heater Control Module sending a request to the FCM to provide blower motor activation or deactivation.
