No heat on driver side

Good afternoon,

Do you have good heat on the passenger side?

As far as the drivers side, there is a blend door actuator. Can you hear the door move when you change from cold to heat?

Removal and Installation

NOTE: The LH temperature blend door actuator is present on dual-zone Electronic Automatic Temperature Control (EATC) vehicles to control the LH temperature blend door only. Vehicles equipped with Electronic Manual Temperature Control (EMTC) are not equipped with this actuator. For EMTC vehicles, refer to Temperature Blend Door Actuator - RH See: Air Door Actuator / Motor, HVAC > Removal and Replacement > Temperature Blend Door Actuator - RH.

1. Disconnect the LH temperature blend door actuator electrical connector.

2. Remove the 2 LH temperature blend door actuator screws.
- To install, tighten to 3 Nm (27 lb-in).

3. Remove the LH temperature blend door actuator.

4. To install, reverse the removal procedure.

Hi Roy,

The heat is very hot on the passenger side. I can hear the door move and I can see the cam on the actuator moving back and forth. Do you think it is bad even if it does move back and forth? If I remove it, is there anything that could be telltale?

Thank you,
Andy

Remove it and see if you can turn the door manually and see if you can get heat.

If you can, then yes, it is the actuator. If no, then most likely an issue with door in the case.

This morning it is working on all settings and I did not touch the actuator! Interesting!

The door or the actuator may be sticking.
