Lights in window switches stay lit

[Cuzzy77]

I replaced the miniature bulbs in my ac/heater outlets, and the left turn signal bulb in the instument cluster in my 91 300e recently. Now, all of the lights in my window switches, mirror control, speaker fader, shift indicator,seat memory(on the driver's door) stay lit...all of the time. My ac/heater outlets, headlight switch, climate control bulbs are all out...all of the time. I did have one window light not working (driver's side rear) and found a loose wire. I re-connected that to the pin in the switch and that light works. All of the swiches work and my climate control works...just not the lights. Please tell me what I did, and what I can do to fix it.
