2010Glk350CDN

Hi guys very interesting site. We have a 2010 GLK 350 and all of a sudden the passenger side seat controls on the door just stopped working. I checked the plugs under the seat and also fuses and relays.... but no luck ! everything else is fine and we love our GLK! can anyone help? Thanks.

Sounds like the switch contacts might need cleaning or the switch itself might be bad.

If you can remove the switch panel try bridging the circuit (bypassing the switch); if the seat moves the switch is the culprit.

Then decide to replace or repair...
