Mercedes Repair Questions? Ask a Mechanic for Answers ASAP
Hi, it sounds like you may have a fault with the PSE module in the trunk. Check fuses 25 and 26 and see if either are bad. If the fuses are good you can try disconnecting the battery cables and joining the two cable ends together for a few minutes then reconnect them to the battery. If you have no success and the door locks don't work with the remote or with the switch in the car you will most likely need to replace the PSE module in the trunk.
