So, spent the day with the girlfriend going on a pretty awesome drive through the mountains in the Prelude, taking the long scenic route on my way to see a friend. Was a wonderful time and for the most part the weather played nice until I dropped her off and began heading home, at which point a massive storm rolled in and dropped a monsoon on us.
It was bad enough that I was running my wipers full blast and the car next to me hit a huge splash and sent a massive wave over my windshield. I guess it was too much water for my driver's side wiper arm, because I heard something go "ping!" and it stopped working. I pulled over into a gas station and after about 15 minutes, got the assembly and trim pieces apart enough to see that the arm that connects the wiper pivot to the motor gear was no longer connected. Apparently the plastic piece that hooks to the gear snapped from the strain. Looks like I'll be hitting up the '86 'lude in the Pull-A-Part next weekend to get that part. Oh well...
I wound up taking the passenger side arm loose and re-positioning it so that it's pointed nearly straight up on the windshield and when I engage it, it wipes the driver's side instead. It should do okay for a week, it seems.
The silver lining? Now I feel like one of those LeMans cars with the one central wiper.
