Hello and welcome.

Have you checked the freon charge?

Is the driver side a little cool at all or completely warm?

Ok. Then you most likely have a drivers side temp door actuator that has failed. There is one for the drivers side, and one for passenger side.

Here is a pic of what they look like. There are several on this system for temp, mode, recirc. The parts listing from the parts store will show the exact location for your vehicle.
