The heat on my 2002 Galant has stopped working just in time for winter. For some time it had been erratic and would only work if the temperature knobwas turned all the way to cold before you started the car, and then turned to heat afterwards. When the heat did start working, it was accompanied by a sound like a fan blade with something stuck in it. I have checked the fuse and dismantled half the dashboard checking for loose or shorted wiring and found nothing. Does anyone have any suggestions on what to try next?
