Passenger door not unlocking?
Just bought a 2000 ML320 luxury and I'm figuring out all the issues it has at the moment,
One particular one is the key will unlock all doors and tailgate except passenger side front (this is a RHD model) and the interior lock button does not lock the FL door either, neither does driving over 15km/h but all other doors do. So to unlock I have to open from inside or to lock push the button down.
What could the issue be?
Thanks in advance
