LOL, you guys crack me up. If a relative newcomer (he's got 53 posts now) searches and brings back an old post, everybody complains about it. But if that same newb starts a new post, everybody jumps all over him or her for not searching. I guess you're damned if you do, and damned if you don't...
As for the wiper switch, I don't see what all the fuss is about. It should take all of about 5 seconds to figure out which direction is faster, and which is slower. And the only installation comment I can think of is to be careful not to break the cheesy plastic tabs that hold the steering column cover in place. I did the installation in the cold of winter, and it took very little force to bend one of the tabs too far. I glued it back on, and it's been fine for about 16 months now.
