Rear Window Washer

My 1987 Accord LXi's rear window washer doesn't spray the rear window.
I pulled the hose off the front right hand sprayer to see why it
wasn't spraying the right side of the windshield. I cleared the hose,
between the two sprayers, removed the sprayer head and found the jet
that sprays the right side was clogged. I cleared the jet and now it
works (some what). How do I check the hose that supplies the fluid to
the rear window sprayer head to see if it might be clogged or if the
head jets might be clogged? I was able to pop the front one out of
it's hole in the hood, but how do I pot the back one out without
removing the head liner in the car? Or, where does the hose run to
supply the sprayer? I know the book says they both (front and rear)
use the same reservoir, but how doe the washer fluid get from the
front to the back?

Thanks,
