It's almost embarrassing to admit, but for the first time in the decade I've had the Sleeperwagon, today is the first time that all 4 power windows were fully functional at the same time. Between busted sliders, fussy regulators, bad switches, and brittle wiring, at least ONE window has always not worked. Well, today my 10yr old and I pulled the back doors apart and replaced the last of the broken sliders, and fixed the wiring on the driver side switch. It's fun when a kid's eyes light up because he finally knows how something works that he never understood before. And believe it or not, he has a pretty good understanding of electrical circuits from, (get this) PLAYING MINECRAFT. :O who woulda thunk?
