When the heat is on, the driver's side is only cold air, but passenger side is warm air.

Hi,

In the HVAC system, there are control actuators that open and close different doors to allow heat or AC to enter the vehicle. On this vehicle, there is one for the left and one for the right.

Chances are the one on the left has failed. Have you ever noticed any clicking sounds from under the dash?

Here is what I recommend, first, take a look through this link, it explains in general how to replace a blend air door actuator:

If you look below, the first two pictures are the directions specific to your vehicle for replacement. Note that the accelerator pedal needs to be removed to access the actuator. Therefore, the remaining pics are the directions for removing and installing it.

Let me know if this helps or if you have other questions.

Take care,

Joe
