Have Mercedes Questions? Ask a Mechanic for Answers ASAP
Hi, sorry for the wait on this question. For your door locks you will need to check the PSE pump located under the rear seat cushion next to the battery. Sometimes water gets into the pump and damages it. If none of your signals are working I would suspect a fault with the turn signal switch. All fuses should be checked. There are fuses under the hood in the main fuse box and under the rear seat next to the battery and at the end of the driver's side dash in the light switch module. Sometimes disconnecting the negative battery cable for 15 minutes will reboot the vehicle network and get things working again.
Let me know if you have any questions.
