Windshield Washer Fluid Not Working
I suddenly have the washer fluid pump not working.
The headlights get fluid but not the windshield. I presume that's separate from the windshield.
I checked the fuse box on the engine. No issue.
Q1. I have 91K on the car. Is this a common failure at this stage?
Q2. Easy to replace?

YouTube has a DIY video for the C300 washer pump replacement which is pretty much the same except I suspect you have 2 pumps off your reservoir. RockAuto, FCP Euro, Pelican Parts are all good sources for a replacement pump. "Q1---can fail yes at that mileage particularly if you use it quite often"
"Q2-- depends what you call easy..have to take off D tire, remove inner liner grommets, nuts. You'll need some tools but certainly very doable for most people. Some aftemarket pumps don't have the OEM MB connector so some electrical connector work might be needed. Pretty sure the Pelican and FCP Euro pumps are plug-n-play.

Just replace the pump, it's pretty easy to replace. Don't cheap out and buy a cheap pump though, I did that and it failed on me after a few months. I got the OEM one off amazon for like $25. Also, those cheap pumps will only spray about halfway up the windshield, which is super annoying. Make sure you get the Continental kind, which is the same as the OEM. Replacing it is easy, but requires taking off the wheel and the fender lining on the front driver side wheel.

i bought my car from a dude and didn’t notice, but once I did for 6 months only drives worked. I sprayed windshield wiper fluid for 10 min straight constantly refilling. Then next day both worked lol
