What can be issue here? Can't find schematiocs/parts assembly to show breakdown of under the dash vents.
AnswerMODE DOOR ACTUATOR (MANUAL A/C)
The mode door actuator is located on the lower left side of the A/C- Heater housing. This actuator controls the position of the panel/bi-level door and the floor/defrost door.
Power for the mode door actuator is provided by the Body Control Module (BCM) on the C26 circuit. This is a 5 volt feed.
Circuit C35 is the mode drive circuit from the BCM to the actuator.
The C37 circuit is the feedback from the actuator to the BCM. The BCM uses this information to adjust the door to the proper position.
Circuit C57 is the sensor return to the BCM. This circuit is spliced with the blend air door actuator.
Circuit C34 is the common line that is spliced, and connects, to the blend air door actuator and the recirculation door actuator.
