Could you maybe explain the problem more clearly? I don't quite understand what you're asking.


The gauge cluster is acting up. gm said to replace cluster but it still the same. "acting up"= lights bells flashing on and off spedo and tac not working once in awile it works great if t shut the truck of . pull key out . turn fan to 3,4 or 5 the blower starts and stops the head lights flash too


With those systems being affected, I would be looking at the dashboard and engine compartment wiring harnesses and possibly even the Body Control Module or the main computer.


Ok i'll start with the wiring harnesses What about the key switch ?

Judging from the symptoms I think the key switch is probably good, simply because everything is getting power, but it could be worth testing just in case.


have you replaced your alternador.if so check your wires behide your dashboard.
