My heated seats suddenly stopped working today for the driver side, passenger side seems to work fine. The lights turn on when i press the button to activate them and then turn back off right after. Has anyone experienced this or know how to fix this? See attached video.

Update: Looks like it was just a one time glitch (hopefully). Issue went away after about an hour of leaving the car and coming back.

I had the same problem yesterday. I scanned the car but it didn’t have any trouble codes. In my
case at least the car battery is coming up on 6 years old (!!!). I’m sure I have a new battery in my future. I remember when the battery was going bad in my W212 E350 that when I first started it up that certain things wouldn’t work. For instance the heated seats, then the Auto start stop quit working. I got a new battery and everything worked

Yeah i scanned mine when it happened and nothing as well. I think it could be related to the battery since i had recently removed it and had put it on a charger. So far it's been working fine since the original occurrence.
