The window washing system is all tore up in my truck and considering all the bugs, dirt, ice, and everything else out here, it's kind of important. So I started taking a look at it before winter.

The tubes from the washer pumps on the resivour are shredded(front) and missing(rear).

Could someone tell me the normal tube route of the rear washer?

There's one tube I found going to the hood for front, and there's a hose near the bottom that's about 1/4" interior diameter, and 1/2" ext dia. However, that looks like it's running down towards the transfer case and has a cap on it. I'd rather not just hook that up without knowing what it is.

There's also a random piece of hose towards the firewall that plugs into the front driver's side quarter panel, but I'm guessing that's some sort of vacuum tube.

If anyone could clue me in, I'd appreciate it.

 

Take a look here, scroll down to the pic under the hood. This is from a '96 Sonoma 4x4. In later models, that ball thing attached to the hood as relocated in the front driver's side quarter panel. This is the vacuum reservoir; stores extra vacuum supply when needed.

The front windshield washer line is somewhat visible at the top of the photo (next to the two electrical wires). Can't help you on the rear glass...never had to mess with that one.

The rest of the pic shows the routing of the vacuum lines and what they do. Hope that helps a little.

 

The rear window hose exits the head liner at the rear hatch so it must enter the a pillar somehow
