Hi Folks,

99 ML 320. Rear door will not lock. (I'm talking about the rear cargo hatch. Not the rear passenger seat door.) If you manually lock it from the inside, it will unlock normally (using either the remote or the console mounted switch). But neither the remote nor the console mounted switch will lock it.

I took the interior panel off and can't see anything electrical or mechanical that is dangling.

I think I need a new rear lock actuator. Could you please confirm and also advise any tips I need to replace it.

Thanks in advance.
