Rear Wiper Washer Not Working

[OR VietVet]

There is a clog there somewhere or the pump is not pushing enough pressure. The water at the hose just before it get to the wiper arm should be a good solid stream. When you used a pin you may have just pushed the clog deeper in there. Find and use compressed air to blow that all out.

I don't own a compressor. That's why I used canned air. I wish I could get to where the hose connected to the spout on the arm but can't. If I could I'd try to blow it backwards from there too. It's been a real pain tracking this. Had my son watch the back when I pressed the sprayer today and it sprays out from the hatch pretty good so I don't think it's the motor.

Sounds like the water getting there is no problem so the arm needs to come off and take to a shop where the rest of the path is blown out. Are you saying where the hose attaches near the arm is hard to get to?

 

[byrds6]

Yeah the part that attaches in the blade itself. If I knew how to pull the hole arm off Id do it myself lol.

I have a 2011 yukon wand my rear washer not working. I pulled the line on the back and nothing comes out. I can hear the pump running but no fluid. I have looked under the truck and no fluid any where. Can the pump be bad if I can hear it running? Thank you

It sure can. You either have some debris at the pump or a broken shaft in the motor
