I had the same problem in my 1990 200 this winter except that
the temp gauge worked OK. It turned out to be the control unit
for the climate control, about $600 and 1.5 hrs labor. Fortunately,
the warranty covered it for me. The mechanic told me that the
most common failure is a spring on one of the flaps or the motors
driving the flaps.

Good luck.
