I can't believe it. Over $50 for this lever? I will just epoxy the damned thing together and see how it goes.For MY 2002-2005 only. (1998-2001 models have a different AC unit.)
The document shows how to replace the control arm/lever that actuator moves in order to open or close the flap, also test the motor.
First, inspect the control arm after removing the footwell top cover. If it does not move with the AC Rear button on or off, use these instructions to fix it.
Other things that may be malfunctioning are; rear air blower located at the back of center console, actuator that directs the flow in the rear cabin, rear control panel or front AC control panel (AAC), etc.
