Headlight switch

Richard, welcome to Fchat. There are a number of threads on this problem. Do a search and be prepared to open things up to get a better look. Good luck.

 

This can be a deep deep subject, but your symptoms sound like the green or black wires inside the switch end knob may have become unsoldered. You can easily pull the end straight off and check them. Be sure to put a plastic baggie over the end of the knob, lest the spring and ball bearing take orbit into the next galaxcy . Also, turning the knob and lever to the off position helps in orienting the stop slot inside the knob. Read all of the many posts on this.

 

If, in fact, you do have a problem with the switch and you can't sort it out yourself, F-Chat member Verell is the recognized expert on fixing them. You can send him your entire switch unit and he will refurbish it better than new. I had him repair the switch unit on my former 308 and he did a brilliant job. You can find him by searching in the 308/328 section. And he's a really nice guy as well.

 

In fact, if you search for old threads, you will find several with lots of pictures showing how to access the switch unit in the steering column and how to disassemble and repair most of the parts.
