Test E: Air Inlet Door Is Inoperative

PINPOINT TEST E: AIR INLET DOOR IS INOPERATIVE

Normal Operation
Under normal operation, the HVAC module - electronic manual temperature control (EMTC) or HVAC module - dual automatic temperature control (DATC) supplies ground to the air inlet door actuator motor through circuit CH208 (GN/OG)/(GN) to rotate the air inlet door actuator 180 degrees to the outside air position, or circuit CH207 (BU/GY)/(BN) to rotate the air inlet door actuator 180 degrees to the recirculated air position. Ignition voltage is supplied to the air inlet door actuator through circuit CBP37 (WH)/(GY).

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