Disconnect driver temperature actuator(Air mix actuator) and A/C control Module main harness connector.
Connect (+) terminal of battery to WARM(+) of driver temperature actuator(Air mix actuator) and (-) terminal to COOL(-) .(Component side)
Verify that the temperature actuator operates to the WARM position.
Verify that the temperature actuator operates to the COOL position with reverse connecting.(COOL(+) and WARM(-) ) .(Component side)
Specification : Refer the specifications in Fig.1)
Actuator harness | WARM(+) | COOL(-) | Door position |

![]() | ▶ Check connectors for looseness, poor connection, bending, corrosion, contamination, deterioration, or damage. Repair or replace as necessary and then go to "Verification of Vehicle Repair" procedure. |
![]() | ▶ Substitute with a known-good driver temperature actuator(Air mix actuator) and check for proper operation. If the problem is corrected, replace driver temperature actuator(Air mix actuator) and then go to "Verification of Vehicle Repair" procedure. |
