Heater not working on drivers' side?

Hi,

On most vehicles, this would indicate a faulty blend air door/air mixt actuator-related issue. However, and correct me if I'm wrong, this vehicle doesn't have dual climate control.

Instead, the air temperature entering the vehicle is controlled by a programmer which receives your request and then adjusts the temp as requested.

What I suspect is the controller isn't fully operational. So, here is what I suggest: Confirm the controller is responding correctly and isn't failing.

Take a look at the pics below. I provided the diagnostics related to the air temp programmer. Take a look through them and let me know if you are comfortable performing them.

Let me know.

See pics below.

Yes I will try.
