Test K: Temperature Control Is Inoperative/Does Not Operate Correctly - Manual Climate Control

PINPOINT TEST K: TEMPERATURE CONTROL IS INOPERATIVE/DOES NOT OPERATE CORRECTLY - MANUAL CLIMATE CONTROL

Normal Operation
Under normal operation, the temperature blend door actuator is supplied voltage on circuit 248 (VT)/1040 (RD/BK) and ground on circuit 57 (BK). As the temperature selection changes it varies the voltage on circuit 437 (YE/LG) to the temperature blend door actuator. The temperature control potentiometer receives voltage from the temperature blend door actuator through circuit 436 (RD/LG). Ground for the temperature control potentiometer is supplied from the temperature blend door actuator through circuit 600 (DB).

This pinpoint test is intended to diagnose the following:
- Fuse
- Wiring, terminals or connectors
- Temperature blend door actuator
- Temperature control potentiometer
- Stuck or bound linkage or door
