There is a door switch on each door that causes the light to go on when that door is open. Sounds like one of them has gone bad. Take the drivers door switch out first (it is the most used) and see if problem continues. if not, you found your problem.
Generally speaking, the radio and some other circuits "keep power" after you turn the key off for up to 10 minutes. When the door is opened and the interior lights come on, the power source is supposed to be turned off. This "keep alive" relay could be in the body computer or it could be a separate relay. You may need to have a shop take a look at it, or get the shop manual to have the wiring diagrams and test procedures.
You are on the right track...the problem appears to be on the driver side rear door actuator switch...locate this spring loaded sensor usually on the inside of the door by the hinges...spray it with PB Blastor, or WD 40...(Blastor works better) and move the switch back and forth...this should loosen up the sticking actuator and return your Buick to normalcy...Hope this helps
That buzzing sound was probably a short circuit in the switch panel. You will need to take the door card out and replace this panel. First check the fuses though. You may have blown a couple of extras because of the short. Did the door get wet on the inside somehow?
Try a window ,see if they still work too . RAP relay supply's power for radio windows etc. when key is turned off for ten mins or till a door is open .
Hiya
Check all 4 doors to see what works and doesn't work, be sure the interior domelight switch is set to turn on automatically when any door is open as well try the radio then open the 4 doors to see if it turns off...if your driver's side door don't work as you stated then that should be the door's "at fault".
GM built the door contact switch that's installed INSIDE the door-it's located inside the door striker/jamb area...it require removal of door trim to gain access.
However, you might want to try this visual inspection:
Check the thick wire harness located between the front-left door and door sill frame to see if any wire has been disconnected/cut or tampered with by previous owner.
