Driver's door lock - Interior lamps not working

Hello,
Thanks for providing so much help in the past, but now got another issue....
I'm sure it's a common problem but thought I'd ask.

When locking the F, I have found the indicators don't flash, but the doors do lock when using the remote,and the LED stays lit. However, when I use the key, the doors lock and then unlock straight away.

Something I have noticed is when I look at the catch on the door, the catch doesn't rotate all the way. Using a screw driver to push the catch round till as far as it goes will illuminate the interior lights. Then when I use the remote to lock the door, the indicators flash, the doors lock and the LED flashes.

If I then lift the door handle and roll the catch anti clockwise as if opening the door, the alarm does go off.

So it seems that the issue appears that when I close the door, the catch isn't rotating clockwise enough.

Anybody seen that issue?

Thanks in advance.

Lithium spray grease in the barrel works wonders.

Don't use WD40. It dries out and goes sticky allowing dust to pulled up.
