I have a 2002 Chevy trailblazer from time to time I start the car and the door locks, instruments (except speedometer and tach), radio, Air compressor and windows stop working. The car runs fine just these things stop working. A/C fan works just not cold air. Also a bunch of warning lights come on on the dash. Sometimes I shut the car off and then back on they come back. Sometimes it takes a few off and ons before it works again. I have replaced the 125 amp fuse which did not fix the problem.
Any suggestions?

Thanks,
JB
