Rear Window Washer

Hi there

The rear window washer has stopped delivering fluid.....

When I hit the button, the rear wiper moves just fine, and I can hear the pump under the hood to deliver the fluid but nothing is coming out the rear.

There is plenty of washer fluid and it still works fine for the front windshield.

I suppose I need to trace the hose and look for breaks.

Does anyone know the route that the rear window washer hose runs on a 2003 Pontiac Montana.

I don't know the route, but is the pump pumping? Try removing the hose and see if fliud is coming out. Then see if the line is plugged. If it's leaving the reservoir and not making it to the back, you would think it would eventually show up somewhere.

I believe the hose for this runs under the headliner,( between the roof and headliner). If it was leaking I would think there would be evidence , like a stain on your headliner, or a drip.Also check the sray nozzle on the rear to see if any debris may be blocking the opening.

On my 2000 Montana the hose that feeds the rear kept coming off the pump which sits underneath the tank in the engine compartment. I think my 1995 Trans Port did the same thing as well.
