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 three positions, Low, Med, and High. Toggling the A/C-Heater Control Module's Power Switch on and positioning the Rear Blower Front Control Switch in the Rear position results in the A/C-Heater Control Module sending a request to the FCM to provide blower motor activation. Toggling the A/C-Heater Control Module's Power Switch off or rotating the Rear Blower Front Control Switch off of the Rear position results in the A/C-Heater Control Module sending a request to the FCM to provide blower motor deactivation.
