Volvo Repair: faulty power door lock, v70 glt, solenoid

Question
My rear passenger door lock on the driver side of a 97 V70 GLT can lock but will not unlock using both the remote and the electric door buttons.  I assume the solenoid is bad.  Assuming the solenoid is bad, how do I take off the door panels and access the door solenoid for replacement?  If I am wrong what would you suggest for diagnosis and repair.

Answer
IT WILL NEED A DOOR LOCK MECHANISM. REMOVE THE SMALL SQURE COVER INSIDE WHERE YOU WOULD PULL THE DOOR TO SHUT IT.THEN REMOVE THE TRIM AROUND THE HANDLE USED TO OPEN THE DOOR,THEN REMOVE THE TORX 25 SCREW INSIDE WHERE THE SQUARE PLUG WAS REMOVED.THEN THE DOOR PANEL WILL JUST PULL AWAY AT THE BOTTOM THEN LIFT UP TO RELEASE FROM TOP TRIM.
