Slow electrical drain

If I leave my 91 200Q for more than 2 days without running it - the battery gets too weak to start the car.  I have checked the obvious (radio on, alternator not charging etc.) but haven't found anything.

A month ago I did notice that the interior lights would not always shut off and replaced that relay, that seemed to help, but not cure the problem.  I have also noticed that the power to the windows seems to be 'on' all the time - is that just a relay as well?  Cost? The other thing I've noticed is that the alarm (stock) doesn't always come on (sound horn) when I lock the doors - don't know if they are related or not . . .

Any ideas of where to look or how to track it down?
