The rear door locks are not working, electrically, wroth the remote or the buttons on the front doors.
The manual, push-pull knobs work fine.
Both front doors lock & unlock just fine.
I have checked power on both sides of fuse, battery voltage is there.

get it scanned for codes it can be a remote receiver problem or a body module problem, probably the latter. you can check the dk blu/wht wire it supplies power to both doors to open.
