My middle interior light is playing funny buggers with me.

I know there is supposed to be the following to it

a permanent +12 supply
A permanent -ve supply
A switched wire which switches with the door opening or closing.

On this switch wire I get either Zero Volts or +4.5Volts.
Why do I not get +12 Volts here when it is switched?

The light works if you manually turn it on but does not come on if the door is opened.

Any ideas what the hell could be causing this?
