2005 chevy venture, had a leaky windshield. water got in the fuse box. power windows, door locks, interior lights and the remote key fob work sporadically. fuses are all good, window and lock switches are good. any idea what this might be?

 

leftover water. condensation. corrosion and or rust. you may have to pull fuse box and clean/dry every terminal. i have heard of people using brake parts cleaner spray. pull fuses, spray each terminal, let it dry completely before putting fuses back in.
