I am trying to fix power door lock problem.
When i turn key in driver door it locks that door but quickly unlocks
If i try to lock pass door pins on driver side door and pass door
  go down but don't lock and motor inside pass door keeps running
and buzzing. Rear hatch lock doesn't seem to work at all electricaly.
I checked all motor assemblies and all seem to work but not as a system
Any help appreciated
TIA
