Finally sorted out the Passenger door closing issue.
I've adjusted everything possible to try and pull the door in closer....to no avail.
Even with everything adjusted as far in as possible, there was still noticeable play in the latching mechanism....ie I could grab the handle and still push it in further / rattle it.
On with the specs. and....there you go!.....the actual
strike mechanism was worn out of shape from years of opening and closing....
I wasn't really keen on pulling the door apart to replace the latch mechanism, so on with the foil cap... out with the MIG and battery earth disconnected.
First up, get a good, close earth to the lock itself.
I decided to replace one of the retaining screws with a longer bolt for the earth clamp to grab onto...worked well.
A bit of filling with some 0.8mm wire and a slow adjustment with the Dremel and it's back to its original shape....well, close to it !
Door closes perfectly now...pulls up tight against the seal and without any rattle.
Job done, time to pay myself with beer.....
So, if like me you've tried every possible door adjustment trying to get a nice, snug close fitting door.....take a closer look at the mech. itself.
If it's mishapen, it could well be the issue.
