Hmm,

This could be related to a couple of things (don't you just love pins!)....All good fun.

Can you do me a favour and go into the test menu and select switch levels and report back (T.2 on the menu).

If you can actually get this far, then it may just be a ground issue on the door (loose bolt or screw).

I had an issue with the switches on the door, but we won't go down that path just yet.

There are a couple of connectors which could also be at fault which we will get you to reseat as well, but one thing at a time.

If you get stuck I'll take some photos for you.
