Hi all,
I have the fix.
I know this is about 4 year later :) but I came across this issue today with my H3 and found this thread while searching for solutions.
After trying a few of the solutions mentioned here my Dad and I decided to just take the door panel off.
Here is a video of the fix https://www.youtube.com/watch?v=uekl62gGW-4&feature=youtu.be
Hope this helps anyone who finds this thread now.
