2003 2500HD, I changed my mirrors to aftermarket GM style towing mirrors. The first set, the drivers mirror didn't move left/right, but everything else worked fine. The replacement mirrors finally showed up, and I just changed out the driver side mirror. Everything (including passenger door) worked fine when I was finished. The next time I got in the truck, nothing on the passenger door works, no window, no lock, no mirror. Any help please?

So I'm new to this site, and these trucks. From my profile name, you can see the previous truck I've had for that last 20 years...
