The heater has quit, engine gages inop, speedometer seized up, and four wheel drive will not engage. Other then that it is in great shape. :Shock:
(This is not a good thing as I am in Alaska)
It all happened at once, so am assuming that it has a common link but not sure what or where.

This has occured once before right after startup but when restarted was OK
Do you

FYI
I guessed correctly as my troubles were with the ignition switch mounted under the dash on the top of the stearing column and totally out of view. One part of the switch supplies power to the 4 wheel drive circuit, the heater and also the gages. New switch $22. + A few hours work 8)
