Hi all: In my 03 Cooper, my driver's side door hinge is barely sticking; not at all on an incline. I cleaned the hinge; that didn't help. I compared it to my passenger's side hinge and it looked no different

Any suggestions?

 

Check your window seal and see if the door is actually shutting. On my Mini, the seal around where the window fits in when the door is shut had some dirt in it so the window could not fit into the seal thus the door would not shut all the way.
