Master window switch replacement
The rear passenger window on my 2019 GLC300 goes down but won't go up. The dealer wants $400 to replace the master window switch but I found an OEM switch for $115. They said it looks like moisture got in the switch and I just got my windows tinted, so I'm guessing they caused the moisture. It looks like it just pops out and the new one goes in. Is it that simple?

I've removed door panels before, in other vehicles, and most are assemblies that snap into the opening in the door so it should be a simple operation to unplug the old and replace with the new. Sometimes you may be able to do so without taking the door panel off but I'm not sure what's required for the GLC.

I did it a couple of times on my 2009 CLK550 (bought the wrong switch once, lol); toughest part was rehanging the door panel correctly (I'd recommend taking some photos of the window's path before you start, window down and also up an inch or so; seems like there are 2-3 slots that all feel right, but only one is).
They diagnosed the issue to be in the master switch and not the one in the rear door?
