That outdoor temp thermometer in the RV mirror on my Suburban has gone
flakey on me. Occasionally it works right, but most of the time the temp's
around 125 (even when there is snow on the ground). The compass works fine.
I'm guessing it is a problem with the sensor or grounding. Anyone know where
to find it? I can't seem to find any wiring diagrams. I believe it is in the
engine compartment. I really love it, but not enough to plunk down a few
hundred $$ to the dealer for a new one.
