Hi- I have a 96 Winstar with 160K. . . been a problem free car for me, but. . .
The hot-cold dial on my heater control SEEMS to operate fine (it feels normal when I twist it) BUT sometimes the heat doesn't respond. In otherwords I turn it to hot but the heat stays cold or I turn it to cold and the heat stays hot. I'm assuming some interal part is sticking. Probably clogged up with dog hair and all the other filth that flies around my van. Moving the knob back and forth quickly will soemtimes free whatever is stuck.. .I hear a barely audible 'clunk' and the heat comes.
Anyone have recomendations for what might be sticking and how I get to it to clean it (or replace it or oil it or whatever I need to do)?
thanks. -Nate
