There are known issues with the gauges on the 03 silverado. Even though the cages appear analog, they are stepper motor controlled by the computer. This is a fancy way of saying digital. Check with the dealer about a recall! Since all gauges appear to have quit at one time I would agree with a previous post that the computer program is flawed. It may need to be reset - again check with the dealer.

check power steering fluid. first. if all good . power steering is going. your hydro boost brake system depends on the power steering pump if it goes out your brake go out.

If your idle is going from 500rpms to 1000rpm's fluctuating at and idle your EGR valve is probably carbon up and needs cleaned or replace.
