1999 ML320 Locks not working

My mother in law has a ML320 that the door locks do not work, the remote will arm and disarm the alarm but not lock or unlock the doors. The center console switch does not work either. Thank you very much and have a great day.

When you say they do not lock, do you mean that none of the locks move at all or is it that they do lock but immediately unlock.

None of the locks work at all, I can arm and disarm the alarm but the locks don't work. If I use the console switch they do not work at all. They do not work at all.

If you read page 13/1 of this diagnostic manual, you can determine that your MIL needs a new AAM, provided all her fuses and relays are OK, and her AAM has voltage supply. --> http://www.benzworld.org/forums/atta...rs-content.pdf

There are tests you can have done to prove which part is at fault.
