Instrument Panel Not Working Right

[dgenerate210]

I have a 2000 Z28 Sometimes when i drive all my lights on the instrument panel turn on Service engine, Brake,ABS INOP, ASR off etc... They all turn on and my my Thermostat and gas and RPM gauges stop working...

Sounds like a BCM issue if all your gauges are going wacky. If you can get to AutoZone or have a code scanner, you should be able to find out what is wrong with your ride. Keep us posted.

I just had it done and they told me all that was showing was Low Bank 2, O2 Sensor... That wouldnt be the reason the instrument panel would go crazy.. Would it??

One of the more important factors in the electrical, BCM etc. is voltage and grounds. Step 1 take off the battery terminals, clean and tighten. Clean and tighten the ground on the fender, and make sure the ground wires at the back of the engine on the heads are tight.
