Mercedes Repair Questions? Ask a Mechanic for Answers ASAP
Hi, FT is the left front door line. You can confirm this by opening and lightly closing the door and let the pump run to try and pull the door closed. If the pump won't run you can reset the pump by unplugging the electrical connectors and plugging them back in or you can remove the fuse for the pump for a few seconds and then reinstall it. It is fuse 62 in the rear fuse box below the passenger side rear seat cushion.
