I have a problem with my climate control. The heat works, as in heat comes out of the vents (if I drive fast enough to push air out), but the blower motor will only come in if it is extremely cold out. The only times it has come on have been when it is below 5 degrees F, and then it will only stay on for a little while, presumably until the car warms up inside.

I know this happens in the defrost setting, but I can't be sure about the other settings as it only gets this cold every once in a while, and I didn't test them all.

It worked properly in the fall, but failed some time early in the winter. I just thought it was the blower motor until it started coming on whenever it was really cold out.

Any idea where to start? I couldn't find info on this type of problem in a search. Is it possible to bypass the auto climate control so I can just tell it "ON" and "OFF?"
