2003 Heating Problem

[bigj1977]

I have warm air in the windshield defrost, and in the drivers side vents, but not in the passengers side vents or anywhere in the rear. Any help would be greatly appreciated. I have checked the radiator is full and everything else seems to be working fine. The displayed temperatures are all accurate and then engine heat is where it should be.

Turns out there is a switch under the dash board...more like two plastic levers that move and pivot. That control whether hot or cold air come through the vents. They can easily come unconnected and then you have our problem. Simply take the dash protector of the bottom passenger side and look straight up near the center of the car and you will see the white plastic levers.
