On the way back from DH biking at Killington, VT last year, I stopped at a gas station with friends ti fill up, had to jump a minivan, and when I got back in, the only functional window was the drivers side. WTF!!??
So I drive all the way to Okemo Mt for dinner with my windows down, thinking that there was a blown fuse somewhere in the truck. After futzing for about 10 minutes at the restaraunt, I finally realize I had hit the D%$@ lock button.
Did I feel stupid. I only had the truck for two weeks at that point and didn't know what everything did.
Lesson learned, "If all else fails, read the instructions".
