Blower Switch (Front)
WARNING: This page is about a different car, the 2002 Dodge Grand Caravan, 2002 Dodge Caravan, 2002 Chrysler Voyager, and 2002 Chrysler Town & Country. However, it is still accessible from the selected car via links, so may be relevant.
The rotary Blower Switch has five positions, Low, M1, M2, M3, and High. The Power Switch must be on to make the Blower Switch 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 respectively.
