Ok, i know this is going to sound stupid and I'm sure there will be some smart comments but here goes........I filled my windshield washer reservoir this week and now it will not spray. It seems like the motor is running when I try it but nothing comes out (front or back) WTH?????????? I know it has to be something stupid that I am missing.

Appreciate the help gang. I guess it was a stupid question.

Try to fill the reservoir again and right after test it, if it is full and if you can hear the motor (pump) and still no water on windshield or under the car, take it to the dealer...many GLKs (mine also) had problems with windshieldwasher reservoir, if your car is under warranty dealer will fix it for free, if no warranty, it is not expensive repair, I paid for new reservoir + work 2000 norwegian kroner (around 250 usd)in official mercedes dealer in Norway and let me say that Norway is one of the most expensive country in the world There is also DIY manual how to change it on this forum few topics lower...but at first I would take it into shop and let them check it for shortcuts, motor malfunction, etc...

Since its a 2015 just bring it in to the dealer for them to figure it out. That is what warranty is for.

Don't think the original question was all that stupid but the sarcasm sure was. Nobody here owes you (or any one else) a response.
