Drivers door switch group not working




I scanned for codes and get: C21500-communication with switch group of control unit door has a malfunction. Do I order a switch or check first to see if the plug on the switch is loose?




Anyway u need to dismantle the door card, be it wire inspection or new replacement master switch

Below probably is very similar, C class

Must have been loose connection, so pulled connector and reseated connector, it clicked in and is now fully functional!!!!!!
Thank you both for the quick response, much appreciated!
