where do I disconnect each end? I think I can probably figure out the rear end, but I have no idea where the front end of the tube would be.

edit: the rear end comes out the center of the rear wiper hinge and goes to the sprayer. the front end is right on the pump connector to the washer fluid reservoir.

I popped off the sprayer jets from the wiper arm and cleaned that out, and I tried the sprayer briefly with the jets removed and some gunk came out of the tube, but not much. The sprayer nozzle was definitely the problem, and carefully cleaning that out, my rear sprayer works again.
