Mercedes Repair Questions? Ask a Mechanic for Answers ASAP
Hi Ed, it sounds like a bad fuse or your central locking pump underneath the passenger side rear seat cushion has failed. The fuses for the pump are in the trunk. Check fuse #3 and 11 in the trunk fuse box. If they are good you will most likely need a new pump.
The fuses are good, I ordered the pump. I will let you know if it fix the problem. I'm pretty sure the pump will correct the problem.
