On the inside of the truck there is a relay center.The relay is marked(on the relay cover)as the inadvertent power.That is the relay in the courtesy light circuit.You can swap it with the one out of the Tahoe.The relay center is on the firewall above where yout left foot would be.Make sure you swap the bcm's back to the proper vehicle the vin is stored in there and will cause problems.That's if it didn't already.

To give everyone an update on this ( sorry for the long delay on this)......... As it turned out, there was a light in the "cluster" above the bed that had burned out. I replaced every bulb on the exterior of the truck, with this set being the last set. Once that set was replaced, I had no more issues with this.

That does not sound right. You may have a bad motor or some type of problem from the factory with the wiring.Is the window straining on the way up? I have had several power windows fail in my 2000 and 2003, the problem is usually a broken transmission mechanism ( cables, etc.). Our winters likely don't help as it is normal for the window to freeze. The problem has not been the motor, nor do I recall the lights getting dim. If it's still under warranty, take it in and I am sure they will replace the mechanism and possibly the motor, it is common warranty failure.

thanks for replying, no the windows do not strain going up, do you think this is a major issue something that could possibly be a huge problem till i get it in, or is it just something minor?

2004 silverado, left turn signal on(only left)and hazards flashed. Hear its a common problem, well I did some research online and it turned out to be an easy fix. All I did was replaced the flasher behind the fuse box and it solved the problem. Was surprised how much the flasher costs though, it was $94 at dealer but you can get it at gmpartsdirect.com for $52. New flasher also has different Delco Part # then stock # and sounds much stronger when flashing. Saving receipt cause i see a recall in the future.
