Windshield wiper nozzle really weak streams - leaks?
The windshield wiper fluid comes out of all three wiper fluid nozzles really weak on my 2015 C300. I have attached a video showing how "weak" it is.
From under the hood, I removed the assembly including the plastic cowl (2058690007) and the nozzles to inspect and didn't find any leaks in connections. I also tried to use a pin to poke the nozzle openings.
Is it likely that I have some hoses leaking between the pump and the parts that I could check from under the hood?

the rubber plug/filter is clogged by the dirt that has gotten into the reservoir over time.
I didn’t need to remove the fender cover completely. Just peeled the cover back a little after removing the plastic rivets and nuts. A few inches of gap was enough to access the pump.

Every summer I tell myself I will remove and clean my reservoir, nozzles and hoses. (big job)
I even bought a Siphon Hand Pump from Amazon, but then found out that inlet is blocking access to the reservoir. SAD.
I was going to try filling it with a strong vinegar / water mix, letting it sit and running it through the system to remove any residue.
Looks like this was solved.
