I shouldn't even mention this, but my kids where in the truck looking around and opened the windows. They immediately fell down. They said "Hey dad the windows don't stay up" I checked it out and thought boy they stinks. After a while I am looking at the outside of the windows and see the name Hehr is sideways. What a dummy I am, I was thinking about my house windows when I installed them. Anyway they are staying that way, at least the kids can't leave them open and allow the rain to come in. :-)
