Driver Seat, window switch, mirror switch malfunction
On my 2016 AMG GTS, My driver-side seat, and window/mirrors have all malfunctioned at the same time. Nothing happens when you move the seat using the buttons or the memories. Same thing with the window switches they do not roll down the windows, and the mirrors won't adjust either.
I have not done anything to the car lately other than a wash and recently added new tires... any thoughts what could be going on?
In my troubleshooting, I did connect the trickle charger in case the battery was low, but that did not help.

'99 and '05 E55 AMG
Door Control Module or Can bus issue. Run diagnostics with STAR/Xentry. If CANBus, diagnostics will indicate if Hi or Low side. Trouble shoot. If not CANBus, you're going to have to probe for short or open on the power and ground wires.
FWIW, on my '99 E55 a failed driver side rear CANBus electronics module controlling the window motor was killing both of my front door control modules plus lower control panel. Sometimes only one, other times two, and sometimes all three. The entire time the rear window appeared to work fine. Was not until I started troubleshooting that I discovered the cause.

AMG GTC
I just had this happen on my 2018 GTC, except for the passenger side. Door controls, speaker, window, passenger seat, mirrors, adaptive cruise, etc - everything just **** the bed for one day. It's at the dealer right now getting fixed under warranty, but the cause was the door control unit as mentioned above. Mine was corroded somehow which caused a short circuit. Parts are at least a month out still (been waiting for 3 weeks already)... would start looking there first.

Thanks for the responses, I went ahead and made an appointment at the dealer but it's not until the first week of December.
In the meantime, I will drive it as is...
After recently having the AC compressor changed, the recirculation cooling pump to the transmission changed, front sway links, all in the last 6 months....it is becoming frustrating

did you find out the reason it happened? And what needed to be changed exactly?

I took apart the old module and it looked fine (no corrosion or anything), but after replacing with a used one off eBay all the issues went away. I let the dealer replace everything anyways with new OEM parts after they arrived.
