Re: Electrical problems--MIRICLE FIX!
the window tracks on those old trucks get cruddy after a while, slowing the window way down. Spray silicone in the window tracks, it will make a world of difference! Also while your in the door, spray lithium grease in the window regulator roller track. Your window will work like new.
Sorry I cant help much with the locks though. but seriously, try the sprays on the window.
