Hi charles j,
Problem seems to be a fault with the air-mix motor or circuit. System is equipped with self diagnostics. Perform the diagnostics and see if you can come up with any codes.
Turn ignition on. Simultaneously press AUTO and OFF buttons, then release buttons. While buttons are pressed, indicator lights "A" through "G" will light up to indicate faulty component. See Fig. 16. If indicator lights come on, test appropriate component.
Fault information is not retained in memory. In case of multiple problems, appropriate indicator lights will light
If indicator lights "A" through "E" light up at same time, common ground for sensors may be open.
