Well, oddly enough, on a really hot day here my temp guage was up around 105 degrees, so I thought I'd turn on the heat to vent it a bit! That's when I noticed that I couldn't get any heat in the cabin.
I'm begining to think this car is cursed!
Olsouth, I'll try the oiling of the shaft and see if that helps. As far as I know, the previous owner had heat the last time he needed it, which was probably back in March. I"ll let you know how it turns out.
