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???
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-
It runs inside the cab. Down along the trans tunnel. When it gets to the
rear seat it comes up under the carpet padding down just left of center
the pump is on the side of the tank. There is a connection there. Then
there is another at the firewall. Inside the line runs down the firewall
into the rear wiring harness to the rear gate. There is a 90 degree
connector under the trim panel/carpet right at the rear of the floor.
Another short line connects to the line in the boot and out into the
gate. Then up to another connector at the nozzle.
Common problem is the rear connection under the trim plate. and the
connector just inside the boot to the gate. If you slide something heavy
on the carpet in the back and it shifts the carpet it pulls the
Another one is if you use the lower grades of washer fluid and don't use
the wiper much the nozzle will freeze. Lift the wiper and unhook the
nozzle from the arm. Then pull the hose off and try it.
Thanks Steve! It was a cracked fitting leading out from the carpeting up to
the elbow by the gate. It's all good now and works perfectly. I was able
to *cut* the cracked piece out of the fitting and still use it with no
problems. It's amazing how far I can stretch a buck sometimes (cost me a
new blade in myutility knife).
