Checking Climate Control Position Sensor Temp. Damper Motor

Checking The Climate Control Function Of The Position Sensor For The Temperature Damper Motors







NOTE: For this test, the climate control and Air Conditioning (A/C) systems must be fault-free. Any other Diagnostic Trouble Codes (DTCs) must be remedied and erased before the function test is carried out.


- Run the engine to normal operating temperature
- Check the cooling function of the climate control system. Set the air distribution selector to the Vent position
- Set the AC button to the ON position. Disengage the recirculation position (no recirculation)
- Fully open the side vents. Close the central vents
- Set the blower fan to maximum speed. Set both temperature selectors to maximum cooling
- Hold a hand over both the side vents to feel the air flow. Check that there is good cooling. Check that the amount of cooling is the same from both sides
- Then check the heat function with the engine at operating temperature
- Keep the AC button in the ON position with recirculation disengaged
- Set the blower fan to maximum speed. Set both temperature selectors to maximum heat
- Hold a hand over both the side vents to feel the air flow. Check that there is good heating. Check that the amount of heat is the same from both sides.
