My ac blows cold air for a few minutes after starting it. Then it will start blowing hot air on the driver side only. I can feel cold air on the passenger side. Do you know what needs to be replaced ? Thanks for the help

Your vehicle has 2 blend air doors. Based on the position of the doors, either heat or AC will enter the vehicle. In this case, the door that controls the driver's side isn't working properly and opening to allow heat to enter. Check blend air door operation and actuator. Most likely the actuator is bad.

The door is located under the dash near the heater core. It isn't an easy thing to access.
