2016 T6 XC90, 59xxx miles
My driver side rear door won't open with either interior or exterior handle. Tried locking/unlocking many times, no luck. The lock makes audible noise inside this door when cycled. I have removed the interior door trim, interior door panel (not super easy with door closed!). Pulling on the cable does not open the door. Behind the interior door panel, there is another plastic panel that nests in the metal of the door. I can pull this back (but not remove) enough to see the cable running well into the metal door shell. The cable remains secured to something at its terminus in the door.
Nearest dealer is 400 miles away.
Anyone have any ideas? Is there an emergency procedure for opening a door in this state? Thank you in advance for any advice.
