Hi, I’m thinking that the actuator(s) need to be replaced. but my question is, which one and where it is positioned? My system is dual control and automatic adjusting. Thanks!

Hello, this Air Temperature Actuator is only labeled left, so im assuming thats the drivers side actuator. You can identify it by the wire colors at the connector. And can I please have your VIN number to make sure this is the correct model. There are 2 different ones. Heres a picture of the connector too, this way you can test for proper voltage if desired. If you replace one of the actuators though, it will need to be programmed and calibrated.

These are the HVAC module (1st pic) and the left side Air Temperature Actuator (2nd pic) calibrating procedures.
