My drivers side door has been acting funny with weird loud clicking noise, I have found out that it was the door strap and when it got to about a 3rd open the door strap would move and then suddenly snap back into position, it would do this 3 times, at 1 3rd open, then at 2 3rds open and then again at fully open, does anyone have any ideas as to what has caused this and how to fix? Cheers.
