I have a 2001 Monte Carlo SS and my gauge cluster will shut off and go haywire all the time. It does not matter whether it is parked or i am driving. Aside from it being really annoying and making my car chimes go off and everything on the cluster not working i can't see how fast I'm going a lot of the time I have seen this problem a lot on other forums for Chevys around this time period but when my cars gauge cluster shuts down so will the thing by my rear view mirror that tells me my mpg and the temperature and direction and what not, sorry don't know what that's called. And my scan gauge that's plugged into my obd port will shut down; however, everything else in my car will stay on including radio, ac, engine, ...etc. I was just gonna replace the the gauge cluster but because of my scan gauge and my mpg/temp thing messing up with it I'm not for sure what to do. I know it could be a short but could the gauge cluster be tied to the other 2 things going wrong simultaneously?
If anybody has had this problem and could please help that'd be awesome!

Either your PCM( engine controller) or BCM (body control module) is defective. Probably the BCM.

 

It's possible it could just be the ignition switch, my 2001 ls doesn't have quite as many electronics as yours but the switch is a known issue and it's pretty cheap and easy to do yourself. Might be well worth it before looking at bigger money for computer modules. My gauges and multiples dash lights including security were wigging out and replacing the ignition switch cured all. Only needed the switch and was able to use the original key cylinder.
