washer fluid low, but it isn't

[AmazinglySmooth]

I have been getting a low washer warning for several months in my 2011 Denali XL. I have filled it, and it works fine in the front. But the rear sprayer won't put out fluid. I can hear the pump working when I push the rear sprayer button, but no fluid comes out.

Any ideas? This is the only problem I'm having currently, so I hate to take it to the dealer just for this.

I found one of the problems. The rear hose became disconnected under the hood--thanks, Google. I still am getting the low fluid warning even after filling it again. Ideas?

Hey there AmazinglySmooth,

I am sorry to hear that you are experiencing an issue with your 2011 Denali XL. I understand that you are looking to resolve this issue yourself without visiting the dealership. I might not be able to provide you with any technical advice but if you find that you have some lingering questions or concerns, please contact me via private message.

The only other thing I could find on the 'net was to see if the unit was oriented correctly. I finally found the location of the sensor (just in front of the driver's side wheel well). It seems to be oriented correctly, so I suspect it just failed.

It would be less annoying if the message auto-cleared from the display, but instead you have to press the button if you want to ignore it.

Mine's doing that too. I tried banging on the resivoir to dislodge the float but it didn't work. It'll go in for service this week. I'm past 36k so i'm sure it won't be covered under warranty

Thanks for the offer but I work at a GMC dealership so I'll just have the shop take a look when they get time.

Ok, I got mine fixed yesterday. The sensor was bad. The sensor was about $19 and the labor was a little under 2hrs. It's at the bottom of the resivoir so they had to pull the battery and the resivoir to get to it.
