When I activate my rear washer fluid pump, I get blue washer fluid that leaks out from the rear passenger cargo area window and drips down the window and into my passenger side rear cargo cubby tray, next to the third row single seat. The cubby catches the washer fluid, which looks like it's leaking from the back window top molding piece. I know it's washer fluid, as its blue color...

Question...does the rear washer fluid hose run in the cab, above the rear window? I am guessing that there is a break in the hose somewhere above my rear passenger side window?

Or maybe there is a hose-to-hose splice in that area that has come undone?

Haven't had time to pull the plastic rear window surround trim and look, but guessing the washer hose runs inside the cab in that area?

Anyone have this blue washer fluid leak before?

Thx!

 

Forgot...this is on my 2004 H2, 75K miles

 

In the diagrams it looks like one piece all the way to the back of the truck.

UPDATE: I took the top rear interior cargo molding off, and the main hose had been unplugged from the plastic 90 degree fitting, before it goes into the rubber protected hose that goes into the lift gate.

Very easy to find! Looks like it was unplugged at some point, probably when the previous owner ran the wires for the rear backup camera.

Hose and fitting plugged in nice and tight, I think they simply forgot to reconnect when the PO did the rear camera install! Work great now!

Thx!

 

Gotta love the easy fix, well done.
