AC doing its thing, then noticed warmish air coming out of the vents. Stopped vehicle, restarted and all is ok. Seem to remember that this is a sign of a blend door not doing its thing. Easy way to fix (DIY).? Tx

Sounds like blend door. If it's the actuator it isn't hard. Yes you can DIY. Basically drop the lower trim panel from the heater box, remove the actuator, replace and put the trim back.

Is it's the door itself that has failed. It can be DIY but it isn't fun....
