I have a 01 blazer lt. a couple weeks ago the gauge cluster started messing up. All the gauges and lights start to go nuts on and off. And the AC will shut down and turn back on ( not just the blower the control unit resets). I have replaced the dash in the truck checked all the grounds i can find, also have replaced the ignition switch and still have the same problem. anyone have any ideas. please let me know. thanks

 

A bad ground in the dash could have the same affect.

 

i hea ya on that ground just cant seem to find it iguess

 

There should be two of them up near the brake (or was it parking brake) on the firewall. Well, in that general area anyway.

 

ill have to take a look and see what i can find. if anyone has anyother ideas please let me know thanks. will keep u posted Kyle on what i find

 

well cant find any other grounds under the dash by the brake or the e brake
