Gents,

I have an issue with my S550 2016 which is when I operate the windshield wipers they are respond perfectly but the washer fluid not coming out while I can hear the pump working!

Does anybody experience anything like this? the reservoir is full.

I need the connection diagram from reservoir till the wiper blade if anyone have it!
VIN# WDDUG8CB1GA244887

 

Should be covered under MBUSA 4-year/50,000 mile factory warranty.

 

out of warranty

 

I understand magic vision wipers are fine. You need to check reservoir fluid although full if you use other than MB fluid some aftermarket products (i.e.: rain-x) can cause pumps (20 & 30 in diagram) or hose line (250) to clog. Check hose nozzles (connection points) at reservoir. Here is an underside view of hose assembly.
