My '78 2dr sedan did something odd today while commuting to work: The door ajar buzzer started buzzing and the dome light turned on while driving.
What is even more strange is this is the first time either worked since I bought the car 2 years ago! The dome light didn't work even when I used the light switch to turn it on. Unfortunately, I never bothered to trouble shoot since both were way down the list of things to fix. The buzzer actually was some thing I was going to yank since I hate key-in-ignition-door-ajar-pointless-buzzing. Since the buzzing was really aggravating me I opened the glove box and yanked the buzzer off when stopped at a red light. I also removed the dome light bulb (the lens has long since disintegrated to dust).
Going home, I put the bulb back in and it did not turn on.
Is it possible for one of the door light switches to short causing the buzzer and light to activate? How else could this happen? I plan to do continuity checks on the switches and check to see if there is power going to the buzzer plug. I should probably try plugging everything in and see if it happens again.

P.S.
This car had other things which were not working when I bought it begin working after I drove it a while: radio; frozen temperature and HVAC selector levers unsticking; something-else-I-forgot.
