Inspection
1.

Turn the ignition switch OFF.

2.

Disconnect the temperature control actuator connector.

3.

[Driver’s Temperature Control Actuator]

Verify that the temperature control actuator operates to the warm position when connecting 12V to the terminal 3 and grounding terminal 4.

Verify that the temperature control actuator operates to the cool position when connecting in the reverse.

Max. cooling

0.3 ± 0.15V

Low voltage : 0.1V or less

Max. heating

4.7 ± 0.15V

High voltage : 4.9V or more

It will feedback current position of actuator to controls.

7.

If the measured voltage is not specification, substitute with a known-good temperature control actuator and check for proper operation.

8.

If the problem is corrected, replace the temperature control actuator.
