Window will not close.

[Usedclassic]

Hi.

2002 Boxster 2.7 83000miles.

I have a problem with the passenger window in that it will not close fully when the car in in use. When locked it closes, but when you unlock the car it opens the 1/2 inch to allow the door to be opened and stays open. The interior light also stays on. The door lock rocker switch on the dash will not lock the car either.

I have disconnected the inner and outer door handle switches in turn, but doesn't help.

I think it must be the interior light switch - is that in the door latch ?

Or has anybody got any other ideas ??

Thanks, Steve
