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

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

Normal Operation
Under normal operation, the temperature blend door actuator receives ignition voltage through circuit A_CBP20 (YE/VT) and ground through circuit GD140 (BK/GN). As the temperature selection changes it varies the voltage on circuit CH439 (GY/VT) to the temperature blend door actuator.

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