Need to take the rear door card off to find out why the electric window doesn't work and the puddle light only comes on at certain door positions.

Presumably it must be a bit of faulty wiring.

Are there any special things I need to know, hidden screws for instance?

Thanks

Check for damaged wiring in the rubber umbilical that carries the loom from the car body to the door, you may not need to remove the door card...
