Question about 2003 Chevrolet Silverado 1500
Fuse is good, bulbs are good. has to be a wiring issue my guess is a short. I tested the voltage in each socket and the wire conector plugging in to the light board. I also tested the voltage to main wire harness that supplies the wires splitting off to each llight board. I have voltage to everything until the bulbs are in then i lose my voltage in the wire before it would even be at the bulb. Any one have any ideas. This is a 91 Chevy 1500 with a 5.7L V8.

A short blows fuses - you have a situation where the voltage is either not reaching your bulbs or possibly a bad ground.
See if you get a hold a schematic for car so you can trace out the power and locate the anomaly.

You certainly have a short somewhere, and tracking down shorts are not ever easy. I would check the dash switch itself, especially if it was working fine before and nothing else was done.

Questions? Do any of your brake lights work? Including Center Stop? Do your parking/taillights lights work? All your bulbs are multi-filiment bulbs that work through mulitple sources. Knowing which bulbs are doing what under all conditions might help narrow down the problem. Meanwhile, check for continuity between, stoplight switch and multifuntion switch (white wire). Also, check DrkBlue/White from MFSw. to Boby Control module. BE SURE to use a low inpedance tester to protect your modules. The DrkBl/Wh wire is your rigth side input. I may be a good idea while testing these wires to wiggle them to look for intermitent shorts.

When this happens it normally blows a fuse. Did you check the fuses for continuity with a volt meter? Sometimes it is hard to see if a fuse is blown by looking at it. If the fuses are ok check under the back of the vehicle, look at the wires to see if the insulation is in good condition and the wire did not burn into. Although if this had happened you would have most likely seen white smoke.

if you have a complete replacement harness it unplugs behind the felt in the trunk. if it is just a socket with a pigtail clip wires about an inch from old socket and use but splice connectors and use electrical tape to cover them back up with.

you must check the connection where the truck harness meets the added trailer harness on the truck itself not the trailer harness.
