Just got this truck, but don't have an owners manual so I'm a little lost...

I tried using the rear washer, but no fluid comes out. I held it for a reasonably significant amount of time just in case it needs to be primed or something. Nothing.

I know the bottle for the front fluid is full... is there a seperate rear bottle? Or does it draw from the same bottle as the front? If so, I guess that means I have a problem.

Is there a seperate fuse for the rear pump? If not, I guess the pump is pooched?

 

Sounds like either the rear pump motor is bad, the rear washer jet is plugged, or a line between the fronty bottle and the rear washer is plugged.
Crawl under the l/front corner of the truck, under the headlight area and you will see one bottle with all 3 pumps.
