HI All, In our 1968 Buick Electra we are having a problem. The low beam head light burned out, which we replaced. About the same time, the dome light suddenly will not shut off. We have checked the headlight switch, the two door jam switches, and the fuse box. If we remove the fuse, the dome light will go off of course, but that is the only way. o No: Thanks for any help!!!!
dome light First, I assume that even if you manually push in the door jamb switch, it stays on. Sounds like you have a bare wire which is acting as a ground. Check the wiring in back of the switches. Perhaps the headlight switch is bad since you should be able to turn it off and on via the headlight switch. Is there a courtesy light switch somewhere on the dash? Check that too. It's doubtful that the problem is in the dome light itself. These kind of gremlins are time consuming to check out. Good luck.
As a vehicle electronics tech, I have fixed my share of these problems. Usually, the reason the lights stay on is that the wire in the ceiling, feeding the ground to this bulb gets pinched between the light and the ceiling, allowing the ground to stay there, creating a light not going out. It is the white wire on these vehicles which is a switched ground, from either dooor or the headlight switch. Unscrew the switches from both jambs, and see if the light stays on. If so, either the headlight swittch is defective, or the white wire is being grounded somewhere else. Ray
I'm having the opposite problem. My interior lights do not work, despite replacing the bulbs and both door jamb switches. Any ideas? o No: David
These lights, like any other circuit, requires two things; voltage and ground. Lacking either or both will cause the lights to not work. First, check for voltage on the white wire. If it is there, you lack the ground. If it is not, the 12 volts to it is missing. We'll start there.
