rear driver side door does not open.
Have you tried unlocking it manually?
Yes, I have tried that.
Then the problem could be in the latch itself, unfortunately the door panel has to come off to gain access to it, and with the door closed this will be very difficult. i recommend that you take it to a shop you trust and have it repaired.
