antenna repair on 2005 GMC Sierra 1500

I remove my antenna (unscrewed) to run through remote wash, replaced antenna and it no longer works, what can I do? will not tighten down and looks like lead is broken off?

If the lead (the antenna wire going to the radio) is broken, you'll need some new parts. Same if you mean that the screw where the antenna attaches, same story. go to the dealer parts dept and ID the parts you need on the computer screen.
If you want to find a specialist, here's a directory link for you:
