99 Yukon rear washer not working..

[the 18th letter]

Wiper works fine but I'm not getting any washer fluid to discharge. I hear the motor pushing, but rear hatch glass is bone dry. Is there a 2nd fluid tank? I checked the fluid level in the bay and topped it off but nothing.

same bottle but at a certain level the rear pump will run dry while the front will not. but since it is topped off i think your nozzle or hose is clogged.

this is a redneck fix from hell but same thing happend too me if you have a air chuck and a air tank this is what you do disconnect the hose from the wiper on the back hatch and pop the top on your fluid resivour next make a tight seal using your hands from the air chuck to the hose push air until you start hearing bubbles coming from the fluid resivour if you hear bubbles you probally disloged the stuck object or ruled out that your line is free regardless make sure you check the resivour afterwords i had a bunch of black shit in there

Not redneck at all. It is a very practical repair idea.

Thanks for this info. I have the same problem with my 07. I will try this and let you know if it worked.
