Wiper and washer fluid not working
This morning I turned on the wiper but no response. I pressed the washer fluid button but no response.
I drover the car to work anyway, the same stock switch works for high beam and turn signals.
I'm hoping it's a fuse.
Does anyone know the location and fuse number for the wiper and washer fluid?
Any other suggestion is highly appreciated.

I feel bad that I misplaced the fuse map, nowhere to be found at the moment. I used the map when I installed backup camera.
Before I go to dealer for a service, I always take everything out and put things back afterwards. Easy to lose things that way.
I will keep looking.

I checked wiper, fluid reservoir motor and rain sensor fuse, #10 and #13 in the engine bay and they turned out ok.
I also tested the reservoir connector for power and it shows 12 volts with car turned off and pressing the button.
So, I'm not sure what could be the issue.
If I knew for sure it's the steering column switch I would replace it but just don't wanna throw money at it.

I found the map in my thick C-Class file pile.
Yes, it says fuse #10 and #13 are for Windshield wipers, front.
However, #13 shows up multiple places either alone or with other fuses, very confusing to me:
ABS/ASR/BAS/ESP, #1, 6, 13, 14, 16, 20, 21
Fanfare horn, #13, 31a, 31b
Headlamp flasher, #13
Multi-function steering wheel, #13
Rear window washer system, #13, 38
Steering wheel adjustment, #13, 62
Switch illumination, #2, 3, 12, 13, 16, 17, 18, 26, 39, 41
Turn signal lamps, #2, 13, 41
Windshield washer pump, #13
Windshield wiper, rear, #13, 38
I am lost.

I called the dealership and they charge $165.00 for diagnostic. I will go that route. If the wiper motor, fluid motor or the actual switch is bad, I will do the work myself.

“car is off", is the key on first notch or or the key is out?
I just tried my car. when key is turned to first notch, pushing the switch will turn on the washer pump and windshield wipers.

With the car off, on or key in the 1st notch, no sound from washer pump or no wiper movement.
I don't know if the wiper motor is bad does the automatically shuts off the pump or not.

I'd think you can try this. With the reservoir connector unplugged, test the pins on the reservoir with meter set for resistance. When the washer switch is pushed, the resistance should be some thing other than open circuit.

I replaced it myself., I would say if you have the right tools it was not that bad of a DIY job.

Just to be clear, I had a shop confirmed that the motor was bad. Because it could be anything with electronics. I paid, I think about $75.00, to diagnose first. I knew I could tackle the task if I knew exactly what needed replacing.

With the bonnet open, I was reinstalling the wipers and couldn’t initially figure out why the wipers and fluid spray stopped working all of the sudden. Turns out the MB engineers were just thinking one step ahead!

Anecdotally too...went for annual State Inspection, inspector popped hood latch in anticipation of checking engine size when he told me wipers were not working, so "no need to continue" until I showed what the reason was. He was then miffed a bit since, when he was fumbling initially for the hood release, I went to point out its position and he indignantly assured me he knew where it was (C300).
