The Ford Kid

Alright my dad has an electrical problem.He had a windshield put in last summer they screwed that up... it leaked all inside.I was driving the truck it stalled when i was mid turn.The next few days it did it over and over.He talked to his friend from the ford dealership and they said they don't seal the windshield right and he had a new one put in and then I started noticing that the two front windows and the drivers rear window fall down like 3 inches after it not being driving for a while.His friend is working on it now has anyone else had that window problem or electrical problem we know all about the water leaking on the pcm and all that good stuff we checked they were dry any other ideas?
