04 C230 Sedan Windshield Wipers not working at all
My windshield wipers are not working at all.
Stalk control arm doesn't seem to activate wipers; nor do the wipers go on automatically when it's raining.
Tried swapping out fuses, and it still didn't work.
Anybody out there ever encounter this?
Suggestions?
Thanks.
Utahkompressor: Are you suggesting swapping out only relays L & Q with new relays?
Ontmiss: Your suggestion sounds so simple, that maybe I overlooked it. Will try.
I'll post the outcome.
Thanks again.

As I have the same. Done all the above mentioned steps and nothing happened. Front wipers and washer fluid not working. All rear are ok. No issues. No codes on the panel.
Any recommendation how to fix that? Thank you.
Diagnostics: Fuse 46 fine. Wipers do Not work on intermittent, I or II speed. Wipers Do swipe for wash cycle (pushing combo switch in once). Assume on/off relay is probably fine because there is some functionality. Hood latch sensor issue ruled out because wipers did not work while driving over 5kmh. By process of elimination I assumed combo switch is faulty.

I have more or less the same problems. No washer nor wiper function in any position. BUT if I move the blinker just a little bit, or even just blink to the left, all functions are working. Could this be a relay problem, or do I need to replace the combination switch?
It took me less than 20 mins to change the combination switch. Even though I got a brand new original part from MB, I must say the construction is no good. The wires are exposed to unnecessary wear and tear, so it is just a matter of time before any of the wires fails again.
Hand, great vid by the way, found it on YouTube first and used it to replace my switch. It was even the same blue wire that broke on mine! The 06 CLK was a tiny bit different but more or less the same. I don't even have an ESP or SRS error lights. Sadly what I am also lacking is ANY functions related to the combi switch (e.g. wipers/washer, turn signals, and high beams). Any idea what I mighta goofed? The WIS for my car refers to using SDS to clear fault codes after but I haven't seen that referenced anywhere else in ppls adventures. Thanks!
My wipers do not work at all, including the wash cycle (pushing combo switch in once).
Fuse 46 fine. But I don't know how to check the relay, want to make sure if it's relay issue before buying tools and part to fix the combination switch.
