Yesterday I set out to tackle the issue of my dome light not working. I have read some posts regarding what to check out. Wiring seemed to be in place. So I proceeded to remove the door switches and clean them up and used some di-electric grease on the contact points to prevent any corrosion. After getting everything back together and opening and closing the passenger side door the dome light worked, hurrah! Then proceeded to check out the drivers side door. It worked also but speratically. As I wiggled the switch in the door the light would go on and off. Upon further checking I have found that the mounting threads in the sheet metal to be stripped. Therefore probably not getting a good ground. I am I right? But my question or problem is what can I do to repair the threads? I tried running a tap throught the hole, but they are to far gone. Can I heli-coil this and still get a good ground? Grind off the old threads and weld a nut to the back side? What other optins do I have? I even went and bought a new door switch just to make sure it wasn't that. This is on a 69 camaro.
