Test T: The Auxiliary Temperature Control Is Inoperative Using The Front Auxiliary Climate Controls
PINPOINT TEST T: THE AUXILIARY TEMPERATURE CONTROL IS INOPERATIVE USING THE FRONT AUXILIARY CLIMATE CONTROLSNormal Operation
Under normal operation, the auxiliary temperature blend door actuator motor is supplied voltage by circuit SBP28 (GN/RD) and ground by circuit GD140 (BK/GN). A signal voltage is received by the auxiliary temperature blend door actuator motor from the front auxiliary temperature control through circuit VHA09 (VT/BN).
This pinpoint test is intended to diagnose the following:
- Fuse
- Wiring, terminals or connectors
