Rear windshield wipers, SPRAYER

[Yetti]

Never had one apart, but if there like the the other mini vans I have worked on the line comes in to a splice, then goes out bound up the piller. I suspect the splice blew or the hose got cut on sharp sheet metal making a turn.

For some reason, I thought their was an issue with some of the rear wiper motor ass. and also something with the rear sprayer.

Sorry I don't have the answer for you, but that's the first thing that popped into my head.
