Seems that all 3 of my windshield washer spray nozzles have lost pressure and only spraying some inches of washer fluid out. Doesn't seem clogged. Anybody have issues with this and solutions? Thanks!

bad pump or clogged nozzle / pipes? use a thin needle to check nozzle ports?

Are they all spraying at the same pressure?

Not to say this is your issue, but mine did the same for a time then quit completely. The washer fluid pump went bad and I had it replaced (factory warranty at the time).

As benzdude said, it could also be a clogged line or debris in there.

Yes all spraying at same pressure. I used a thin needle but didnt seem like that was the problem.

when you do a manual test spray, can you get someone to hear if the pump can be heard?
Try removing the water hose from one of the nozzle (usually the closest one to the tank), and use an air gun (compressor gun) to force air through the hose.

I went to mercedes and they said it was the pump. Unfortunately not covered under my cpo warranty. Seems like a easy job. Anybody have the link for the mercedes washer pump? Or anyone from autozone works? Thanks.

The washer pump and reservoir are located within the left front fender. It requires removing the left front wheel and left front inner fender liner for access.

Unlikely. The words "Mercedes Benz" and "Autozone universal parts" rarely go together. If you are skilled and comfortable working on your car, buy a genuine MB washer pump. They are not expensive, around $30-$40 I think.

Are the headlight washers suppose to open when I press the washer button as well?
