Volvo Repair: power door lock, mirror area, door handle

Question
         I've got a 2000 70XC, on the passenger side front door, the lock will engage but not release with the button. I was told this is a common problem due to a clip that breaks when then unlock is pressed and the door handle is pulled at the same time.
         I would like to repair it myself, could you let me know what part I need ? Maybe the # and a hint on the repair.
               Thanks a bunch, Brad  

Answer
I would need to check for a part number at work .you will need the right front door lock mechanism.the door panel is removed by removing black cover behind mirror area,then remove trim around door handle it jut pulls off.the remove the small square cover in the handle area you pull to close the door.there is a orx25 screw remove this and then the door panel just pulls out away from the door all that holds it is clips.then you will lift up once pulled away from the door.the window will need to be up to be able to get the lock out.
