So I bought the timer that goes to the courtesy lights and they all work now like they are supposed to. Now, I'm trying to figure out why my light reminder buzzer/key in ignition buzzer doesn't work. I need that idiot bell because I leave my lights on. They were invented for idiots like me. But, this time the thing is there, just no workey. Any suggestions?

If I remember correctly these were two different buzzers. The key buzzer works off a small switch under the key tumbler. Often the switch would just wear out. Where the actual buzzer is I'm not sure.
The head light buzzer I remember is a small box that plugged into the fuse panel. Since it was an option on most chassis it was an easy add on.
Hope this helps....some.
