After hours of searching various forums/google I guess my problem lies with the 'door locking mechanism'
Problem - passenger door will not open. Have tried inside handle, outside, unlocking with interior switch, banging the door, pulling handle while unlocking ect.
I can hear the mechanism moving when I unlock the door, but doesn't seem to want to budge.
I am aware that this is a very common problem and there's plenty of info available, but I don't want to spend money on a part I don't need or on the wrong part.
Is it the locking mechanism I need to replace or something else? If so what is the part number?
