rear door, pull on the latch
release handle in the inside
of the door.
To fully open the rear doors,
push in on the clip and lift
the check assembly up off
the mounting bracket.
To close the rear doors, close the driver's side door first.
Check to make sure both doors are completely closed.
The rear doors have a check assembly to keep the doors

the mounting brackets before closing the doors.
