That's bad.

on an 02 f150 the horn trigger is dark blue at the column and sends a ground to the horn. I don't know if that signal runs through the gem, but your problem sounds GEM related. I am thinking one of the chassis grounds maybe getting power and flipping the GEM out.

His GEM sounds shot. Ford can confirm it, but the doorlocks have little to do with parking lights until the GEM goes. Sorry I can't give you better news.

General Electronics Module. It basically controls interior lighting, door switches, power windows, really anything electronic not required to run the engine.

I had to replace my cluster to swap my GEM, including core I paid $515. Yours should be integrated like mine so expect less.
