Hello,
I am trying to help a friend with the 2020 Traverse. All doors, except for the driver's side and the liftgate, could not be locked, either with the button on the driver's door or with the keyfob. it seems like the lock/unlock signals to the power door actuators of the front passenger and both rear doors are common and arrive directly from the BCM. Is there an onboard relay for the power doors on the BCM board? The circuit diagram of the power doors would be appreciated.
Thanks,
Anton.
