I replaced my windshield washer pump. Still no spray. What next?

Every thread that I could find on this matter just had the same remarks saying that it was the pump. I just replaced my pump with a new unit and still have no pray coming from the washer nozzles. What is the next thing that I should check or try to replace? Not having windshield washer spray in the winter is a little inconvenient. Thanks!

I have/had the same issue, in my case the pressure was so great that the rubber hoses came off the sprayers. They are a little tricky to remove...but with a long set of tweezers you can separate the tabs (that hold them in) and remove the sprayers. (nice thing about MB, is they allow you to extend the hood to the service position...almost vertical.. check the latches on the sides of the hinges, to release the hood to service position)

once removed you can clean them/soak them in a vinegar and water solution. (they are heated and the heating element corrodes and then clogs up the nozzle). You should be able to freely blow air through them. If not, wash, rinse dry ...repeat.


As always..usual disclaimers.. DIY at your own risk.

Cheers
