2003 Mitsubishi Galant blows cold air

I have the same problem. After searching on line and speaking with a few Mitsu dealers. My problem sounds like a Heater valve Control Motor, $400-600 repair.

There was "chattering" from the vents prior to the heat stopping. The heat was working, the knob was turned to cold and when it was turned back to heat there was no heat.

Hope this helps.

Does anyone know of a temporary fix to get the heat back?
