Dribbling Rear Windshield Washer Nozzle

Hi,

Sometimes the rear window washer nozzle in my '12 LT1 will dribble a small amount of fluid, just enough to leave a trail through the back window's dust.

Seems to happen most often after I've washed the car though maybe that's just my imagination and I only notice because the car is freshly washed. (I also can't stand ANY water spots and will towel dry post-wash like an OCD maniac)

Sometimes it'll happen over speed bumps and such. While I can understand why it would happen under those circumstances that doesn't mean I think it's okay for the nozzle to leak, ever, especially since it also leaks out of the blue just driving along.

Also doesn't seem to matter if it's hot or cold out, whether I've run front and/or back washers, etc.

Besides plugging it, which is unacceptable as I run the washers if not daily then for sure every other day, does anyone have any ideas on this issue?

Thanks!

I guess you try replacing the nozzle, but I wouldn't hold much hope.

In most wiper/washer systems there is a check valve that prevents the fluid from gravity draining out. I'm not sure if in the Traverse that is in the pump itself or in a fluid line after the tank. I can't find a reference to it in the service manual but I did find a replacement part on Rock Auto...so I bet there is one somewhere.

Certain washer fluids are rough on the diaphragms in the pump and the one way valves. I've had issues using the RainX brand fluid in my Subaru before.

Thanks guys. I'll def. look into both as that was already what I was thinking just hoping someone else had experienced this and had a known solution.

And another thing mildly annoying with my rear wiper is that often times when it returns to it's home position it's not completely horizontal. Sometimes it'll return to home and then up a few degrees. Sometimes it's a lot of degrees where the wiper stops 1/4 up the window.

Anyone else experience this? I just hit the wiper button until the arm stops at the horizontal but like I said it's a tad annoying.

Just my good luck I suppose. Thanks for letting me know. Going to take a look at all the nuts / linkage to make sure everything is tight then move on to relay/switch and if that isn't it then replace the motor.

By no means the end of the world and eventually with enough button presses I can get it to return to home position. Just weird it's not 100% reproducible.

I've had this same issue on random occasions, almost always when I'm just washing the rear window. Never when just running the wiper in the rain.

Yes, mine does this too. Flip the switch again and it corrects itself. Never had it a 1/4 way up the window, but I've had it about 1-2" up from resting.

Well I suppose I'm "happy" to know it's not just mine then even with it sometimes stopping in a crazy position. Thanks for confirming, guys.

I haven't had a chance to check it out any further. I decided to re-do my front brakes as apparently doing the lazy/quick route was not the way to go as my rotors are now wearing unevenly. Took it all apart, replaced hardware, replaced piston rings & boots, cleaned everything and re-greased, filed/sanded some burs on the pads' (Wagner QuickStop Ceramics) squeal clips that were slightly catching on the calipers, etc.
