My passenger door is very hard to open. The car is a US import converted to RHD, so it was the drivers door in it's past life. The handle/lock mechanism seems to release the cog OK, but the door needs a firm shoulder shove to open.
I've eliminated the anti bust catch as the culprit (by removing it), and it seems to be just the spring loaded slidy thing jamming on the sticky-out bit (excuse the technical terms here).
I've played around with adjusting both the entire door and the catch, but I cant improve it. Do I just get a replacement catch?
