On our 2016 C450, the there is a group of 4 switches to control the windows (sitting behind rear view mirror control). On the those window switch is broken, it kind of sticks. Does anyone know if I can just replace that button, or if the part containing the switches can be replaced without pulling the door panel?

Yeah ****ty design, my trunk release switch popped out for NO reason one day only after a month of ownership. Some of the passenger window switches are a tad sticky depending on temperature too.

... And NO I did not discharge anything onto the buttons either if that is what you're thinking!

I'd head to the dealer as you're probably still under warranty.

Already had the button fixed under warranty a couple months back.

Unfortunately not under warranty. Does anyone know if those switches come out without removing the door panel??

It really depends on how it's broken.

If it's just the actual button, (and not the electronics), it's easy and really cheap.


This video shows the process.

If it's the actual module, that's a different story, but the module can be had online for around 50$

Wow, speak of the devil.

Just today, I had my driver window button break. It is not totally off the fixture but compared to the last time this happened, judging by the feel, it is bound to break off in the next 2 days.
