"I am having electrical problems - no gauges, no wipers, cannot turn headlights off, cannot turn heater blower motor off, no aux key position, sometimes transmission will not shift to higher gear, couple other minor things. Any idea what it may be?"

First, have battery and alternator checked for proper operation, an alternator putting out ac voltage will confuse the pcm and make it do stupid dtuff.

Have the bcm checked for codes as it is the common denominator for all these functions

Pcm is the engine computer and bcm is the body control module which all body functions go through
