I've looked at many of the central locking issue threads, but haven't seen quite the same issue I seem to be having.

I have a 1995 525iT. Recently, when I turn off the car, it will automatically close all the windows and the sunroofs. I often like to leave the sunroof in the vent position in warmer weather, however even if I wait until everything closes and then put the sunroof into the vent position, it ends up closing back. It behaves as if I have the key in the driver's door with the key turned toward the lock position to close all the windows from the outside. I am thinking possible GM, but not really sure. Anyone else been down this road?

Thanks.
