At the risk of sounding like a contrary geezer (I am), of all the devices on my bus that need a dose of explosives, the air wipers are at the top of the list. They work, and they will probably work for years without problems...but, unless you have E-Cam wipers, there's no "delay" function (that I"m aware of?? Hep me here!), and the park feature on my drivers side is going to toss the wiper blade one day. It parks aggressively, to say the least. This may be a fault...?
I"m going with electric when the next one fails. Already replaced the drivers side. The plastic housings will age out and crack. Then the wipers lose power.
Don't have to have a pantogram unit...any good quality electric conversion would do.
Anyone want to trade one new and one good working MC9 motors for an electric system?

Just let me know.
I'll even throw in one new and one good control valve.
If you order a wiper motor, be sure to specify which side it's on if you want the park feature to work correctly. The valve body can be turned around to make an opposite functioning motor, but if you get the correct motor, this won't be necessary. And, you won't have to pull it back out to make the mod after installing...like I had to do.
