I'm having an issue with my 2003 ML500.
Full auto machine gun locks, but my issue happens when I try to lock all doors from the inside switch.
All doors are affected.
I've searched my *** off -.and I can't find the fix.
Any and all help is appreciated.

What happens when you use the remote key to lock the doors?

What door does not lock?

Just bought the truck. No FOB, but I did notice that the LR door does lock.

No FOB, but I did notice that the LR door does lock. Do you mean it does not lock?

The driver's side rear door DOES lock when I use the inside lock button. The other doors do not.

Maj. Dundee

Usually one door has a locking-unlocking problem, but never heard of two or more doors.

You will have to read read codes in the AAM (All Activity Module) which controls Central Locking.

Thank you!
