Question about 2003 Chevrolet Silverado 2500HD
Remote keyless entry, (both doors), power door locks both doors, right door power window and mirror adjust will not work. Right window will not work from either door nor will door lock. Turn signal in right mirror does work as well as the one in the left. Both 25 Amp circuit breakers for doors are OK. This came on suddenly. One day it was working and the next not.
You have a relay problem...look under the chevy forum.com or simply google the schematics for electrical relays for your year make and model..GOD bless

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.
