I live in the Sierras and over the past winter I have had a problem with my
instrument panel losing power when I have driven in the cold and snow and
have had my heater on, not knowing if the heater is part of the problem. I
have a 99 TJ Sahara and the first indication I get is that my airbag light
comes on then I lose speedometer and tachometer, then finally the rest of
the gauges. If I turn the vehicle off and restart it about 5 - 10 minutes
later everything is fine.

Any thoughts?
