Programmer Linkage:

The air-mix valve is used to provide the proper mix of warm and cool air as determined by the Body Control Module (BCM) output signals.


The air-mix door linkage consists of a plastic crank arm integral with the output shaft of the programmer, a serrated nylon retainer, and a threaded rod. One end of the rod is fastened to the air-mix door and the opposite end is retained by the serrations in the nylon retainer. The programmer positions the air-mix door by this rod.
