Power driver seat suddenly stopped working
Hi, my 2014 c250 driver seat has suddenly stopped working. It’s about 85% fully back position(with me being 5’5) is kind of hard to reach the pedals. My front passenger seat powered controls still work. I researched online and seen there are trim models of the same year that can have up to 3-4 fuse box locations. Checked all of them and didn’t find any blown fuses(pulling them out and inspecting , and measuring resistance with a multimeter). I never move my seat so I doubt it’s a seat motor problem. My car is always empty and clean so it couldn’t be something that got lodged underneath. I disconnected my battery to clear the ecu and no results. I tried looking underneath(front+rear angle), at the wiring cables and harnesses and they all seemed alright. I was gonna take the seat bolts out so I could lift the seat up and look at check the rail, wiring, maybe reseat wiring harnesses, but the way the drivers seat is stuck(85% back), only the front bolts are accessible, and the seat can’t be tilted, so that idea crumbled. Any help would be GREATLY appreciated. Thank you !

You need to get a good Mercedes-specific scan tool, either XENTRY or a LAUNCH Creader Elite 2.0 BENZ and scan for seat codes. Check the status of the driver's seat for errors. It may need calibration.

Recently someone else had an issue with the seat not moving. I believe they said they disconnected and reconnected the harnesses and it started working again. Worth a try: https://mbworld.org/forums/c-class-w...t-working.html

TWO BIRDS WITH ONE STONE....
you guys know what that quick-fix means, right?
Seat was sleeping on the job unable to receive commands.
CAN-B module was in the lake... soft-crashed in need of reboot!
optionally disabling com between door and seats... and R-SAM likely also!
The wonky CAN-B status is what drains batt while parked to hand-shake with Keyless, EIS....
What you really need is called a "CREADER ELITE MB scanner" to see what 40+ computers are doing or not....
