Ac blend door problem
My ac only blows cold air out the top vents in the front and the floor vents in the
back any help???
you may want to check the flap that redirects the air for defrost. I believe it is hung up
It's almost always the actuator that fails. If you switch settings between vents try and listen for the actuator. If the door is stuck on something (a rare occurrence) the actuator will click as it tries to move it. If you here nothing at all, then assume the actuator is bad. You won't know for certain until you can access it. I usually have a new one on hand, and after gaining access to the actuator, plug the new one into its wiring harness and test it. If I was even smarter I would test the switch before going through all the above just to eliminate the chance it was a bad switch, but that is an even rarer fault.
