Welcome to just answer. Do the locks do a clickity click?
No nothing happens
The locks do not lock or unlock
Ok you need to check this relay in the right side of the trunk. how you test a relay is by putting power and ground on side and see if there is power going out the other side. I am sending this in a jpeg if you need anything else just let me know.

Thanks for the reply, I clicked on the Control Module link and it took me to a login in site for Motor All Data, (do I need a pass word to login?)
Should I replace the control module (N69/5) ??
What is the part number for the keyless go control module?
I called Mercedes and was told my vin number did not indicate I had a remot go keyless control module
Let me check on the part for you in this system it does not show a part# XXXXX am sorry
What is your recommendation to fix the door locks and trunk issue??
My recomendation is taking it to a auto body shop that works on foreign cars. The labor rates are alot less expensive than going to a mercedes dealer Because it is an older vehicle most collision centers have the capabilty of pulling the code. Are there any light codes on. They can simplify it and because it is not considereda mechanical labor your going to save atleast 50%. if you need anything else jkust let me know ok. But according to the systems i have it does shoe the module back there.
OK, thanks for your help, I'll take it to shop.
