'91 525i window lights stuck on

[Gurlugon]

Hey fellas, my old barge o' problems has been acting up again. Dead battery Monday morning, couldn't use the trick to open the doors, had to use a screwdriver to pop the hood. Replaced the battery, it was at least 4 or 5 years old and on its way out regardless so I suspected it just managed to fizzle out on its own.

However, now that things are seemingly back to normal, I can see that the window pushbuttons are staying lit up long after the car has been shut off and locked. No other lights or equipment are on. Short of pulling a fuse, what can I do to fix this? Don't need a new battery going and dying on me! Thanks in advance.

Sorry for the double post, but recent work on the car has been replacing the air filter, the O2 sensor, and the sparkplugs.

My guess is that the relay that allows a final closing of windows after the key is removed is sticking; the window switches are supposed to stay lit until a door opens so you know you can still close the windows. Obviously, after the doors are closed and locked, they should be unlit.
