On my wife's '04 Tahoe the rear window washer doesn't work. I checked the manual which said front and rear used the same bottle, and too check the level. I topped off the jug and tried the switch. It sounded like it was pumping but nothing out the rear. Got out and noticed that the drive-way was coved in the washer fluid. Has anyone ever had this problem? Is there a seperate pump for the rear washer? Maybe the hose off stopped up? Does anyony know of a source where I can maybe get a picture of the jug and pump? Thanks folks.
