Courtesy Lights Flickering?
I took my 75 convertible out for a ride tonight and all of the interior lights were coming on and off when I would hit a bounce. Do I have a bad switch or a rub threw wire?

the switches complete a circuit when the door is open, so it is possible for the switch to be adjusted in to the point that the door barely opens the contacts. then as the frame twists while driving it will open and close just enough to make the lights flicker. I had a similar problem with my door ajar switches. or as said it could be a short somewhere.

Likely a problem with one of the door switches. Open each door on the car [one at a time] and use finger to "play" with each switch to see if it goes on and off without problem. If the problem is not there, it may be in the wiring to the bulbs.

As I drove around I was on a rough road and they were coming on and going off.
I will replace the switches and see what happens.

When I got in the car today and pulled it out of the garage the lights came on. I tried each of the door switches but they wouldn't go out. I took off and drove over some train tracks and they went out.
As I drove around I was on a rough road and they were coming on and going off.
I will replace the switches and see what happens.

If the lights were suppose to be ON and go off when you hit a bump its a bad ground. BUT in this case the lights are going ON when they shouldn't be so its probably not a ground. It is most likely one of two things. One of the switches is faulty and completing the circuit or a hot wire is touching a return wire.
Start with contacts in the doors. Two wires should plug into each. When depressed the switches BREAK the circuit...no power carries through and the lights stay off. Other possibility is the two wires at each switch are loosely wired and when you hit a bump they touch each other bypassing the switch and completing the circuit. Were are your contacts? In the door jam or towards the back? either way you can access the switches and try disconnecting the wires. make sure they are not touching...that will tell you if one switch or the other is bad.
There is a remote possibility the contact is being made in the headlight switch. I assume you have that setting on the switch that turns on the interior lights. Next time they go on turn the **** on the headlight switch. Do the lights go off? If so the problem is there.
