Test A: The Air Inlet Door Is Inoperative

PINPOINT TEST A: THE AIR INLET DOOR IS INOPERATIVE

Normal Operation
Under normal operation, the air inlet door actuator motors are supplied voltage or ground on circuit 1116 (DG), depending on desired actuator rotation, by the HVAC module. The HVAC module then supplies the appropriate voltage or ground to the other side of the actuator motor on circuit 1117 (LG).

This pinpoint test is intended to diagnose the following:
- Wiring, terminals or connectors
- Air inlet door actuator
- HVAC module
- Stuck or bound linkage or door
