rear door on my 2009 cdri 2L diesil wont open using either inside or outside handle ,something clearly broken ,outside handle very loose never had any problems with this side before but other side handle occasionaly comes away in your hand when opening but just a case of putting back on and door works ,is it easy to get door card off to see whars going on inside or has anyone had this problem and know whats wrong ,had this car from new but getting old and done 165,000 miles so not worth much so just going to run as long as possible untill it has a major expensive problem then scrap it hopefully get a few years out it yet
