Temperature Control Actuator Inspection
- Remove temperature control actuator. Refer to TEMPERATURE CONTROL ACTUATOR REMOVAL AND INSTALLATION .
- Check resistance between terminals.
Temperature control actuator resistance
Terminal "d" and "e" (max cold position): Approx. 150 - 250 Ω
Terminal "c" and "d" (max cold position): Approx. 2.6 kΩ
Terminal "d" and "e" (max hot position): Approx. 2.6 kΩ
Terminal "c" and "d" (max hot position): Approx. 150 - 250 Ω
- Connect battery positive (+) terminal to terminal "b" and battery negative (-) terminal to terminal "a". Check if position of temperature control actuator changes COLD to HOT.
- Connect battery positive (+) terminal to terminal "a" and battery positive (-) terminal to terminal "b". Check if position of temperature control actuator changes HOT to COLD.
If malfunction is found, replace temperature control actuator with new one.
