Yesterday everything worked great, today when I started up
the fan is stuck on high, the interior temp is 90deg. & heater is stuck @ 90. none of the buttons on the panel respond.
can’t turn fan, heat off, can’t turn air or radio on. No fuses
are blown…can you help?
Sounds like the Body Control Module is failing.
