Dome lights won't shut off when doors are closed on 1980 corvette.
All dome lights work as they should when car is running. Dome light works
with light switch when car running. Problems starts when key is out. Can't get
dome lights to shut off.
Usually dome lights have three positions, On, Off and On when the door opens. If it is set to On all the time then it won't turn off when you close the doors. If the door switch is defective it could also leave the light on but the Off position would still turn it off.
The doorjamb switch completes the circuit to ground. If water is getting into the inside of one of the doorjambs it may cause the lights to stay on. Water is a conductor. HTH. -Jim
78-82 Corvettes have a courtesy light timer that keeps the interior lights on for a short period of time after exiting the car. That module may have failed, keeping the lights on.
