Another silly 95 Jimmy question - rear wiper hose routing

Do any of you know exactly where the rear wiper hose for a 95 Jimmy is
routed? I can hear the pump but no fluid comes out the rear wiper. I
assume the pump is on the side of the tank but from there does it go inside
the truck under the door sill or is it under the frame rails, or someplace
else?? The roofline?? Anyone???


Thanks!
Andrew.

Andrew-if you have available compressed air-unhook the hose at the
rear wiper(near rear tailgate lock), blow thru it-you may have
something there-, possibly blow both ways if you can. i.e. hose-near
wiper base-bolt on towards nozzle and then back- make sure clear. If
this doesn't work locate which pump it is in the reservoir tank, pull
the hose off and put your compressed air thru this-use judgement on
pulling the trigger on the compressed air(if you have). Also as you
do this if you can have an assistant watch, in the rear ceiling area
near the cargolamp for any fluid leakage there. There is a hose and
connector that frequently comes apart there in the ceiling. You may
be able to substitute your own 'blow power' by mouth-I'm not sure plus
it depends on the blockage. Compressed air is best but be careful.
That hose runs over head and then down left rear corner then thru the
tailgate but the suspicious spots from my experience are as listed. If
your all clear it should work, if not you may have a weak pump(rare)or
a leak in another spot not mentioned but rare. But keep in mind if
the pump is indeed pumping and you have windshield wiper fluid in the
jug-your leak WILL show somewhere. If in doubt about pump strength
you can flip flop the 2 pumps in the reservoir-they are the same.
This may help you troubleshoot a bad pump. Good luck-I'll bet the
problem is listed above here-good luck. Let us know! jerry@peru-
