One door won't lock/unlock

The door at the back of the driver side won't lock or unlock when pressing the black button on the handle. Other doors work, only this one doesn't.

What do you think is the problem? The handle itself?

Same exact thing happened to our GL350 a few months back. Dealer discovered the electronic module in the handle was faulty. They replaced the handle with a new one and it works great. Hopefully your is still under warranty.

This must be for a Keyless go system - correct?

Left front door wont open or lock the rest will. The problem is from within the vehicle and with key, no sound from the one door. Other 3 doors work perfect.

Removed the lock to look inside, spring ok.

What could that be.

It could still be your door lock actuator. If you pulled the door panel and it doesnít move at all when the others do then thatís likely the culprit.

It is the nature of the beast, it does not move.

That would be the whole actuator it self, for e.g. A1647201535, correct?

Just make sure if you have keyless go you get the correct one. It will be the whole actuator.

Unfortunately, Not Keyless go, just ordinary wireless key operated.

A used one on ebay might not be a bad idea. Let me try that and revert.

Thank you so much for your help.

There is always a rush with a used door lock actuator. It may go bad quick.
