Multispace uk drivers side, slide door lock

[lemsworld]

Recently when I have locked the car the passenger slide door on the drivers side doesn't always lock but the rest of the doors and boot all do (luckily I pull a handle before I walk away) anyone have any ideas what the problem could be?

Thank you

Off the top of my head I'd suspect an intermittent electrical connection to the lock, something partially blocking the mechanism or maybe corrosion preventing it from operating at times. Reasonable things to check out since it involves just one door.

Thank you, This has only happened twice and not since but I will try to look at the door when i have a day off
