My drivers door will only close after many attempts at banging it shut, from inside or outside. The door keep is solid and immovable, the catch mechanism is free and will easily latch on to a screwdriver and open again with the handle. I live next door to a repair garage (who know my car well!) and they took a look at it today, but said they got the same results as me and are mystified. The mechanism isn't worn, the spring is strong, the door is in the correct alignment, it latches on to a bar easily, BUT it just won't latch when closed. They doubted that a new lock mechanism would act any differently. (He did suggest welding it shut but I declined} I found a thread from 2013 where someone had the same symptoms but there was no reply. Please, can anyone make any suggestions or know what the problem is??
