Hi, when I turn on the A/C it only blows cool air to the passenger side. The driver side blows neutral/warmer air. Any ideas for what the problem might be? Thank you.

Hello,

This could be due to a faulty blend door actuator for the driver side.
The blend door actuator/motor is what controls the flow or hot/cold air. It can fail in a position when it is stuck in a certain position and not allowing you to change the temperature.
The blend door actuator is located behind the dash on the HVAC unit.

Let me know of any questions.
