R350 (W251) wiring diagram?
Right rear passenger door locks and unlocks with key remote, but other doors don’t respond anymore.
Is this a faulty SAM (Signal Acquisition/Activation Module)?
Seems like this problem is related to the tailgate motor controller fault, causing a christmas tree of lights blinking, relays continuously switching on/off and commanding door and tailgate to continuously lock/unlock. Disconnecting the large connector to the tailgate motor controller stops the blinking and continuous switching of relays and locks, but doesn’t fix the door lock problem.
Need wiring diagram for further troubleshooting.
Who knows where wiring diagrams can be downloaded?

I have a subscription to Alldata, it is way less expensive than the Star Service subscription.
They have wiring diagrams. It is only like 25.00 for a year for a single vehicle.
