'99 Camry - clock and emergency flasher indicator related?

I'm not sure, John, but it is logical that since the indicator and the clock 'memory' ALWAYS have power available to them, that this is a good conclusion. Having a bad dulb would not cause the clock to cease, however. But it looks like your on the right track. I AM assuming you checked the fuse?

Next step would be to remove what you can of the dash and have a look at the wiring; a wire may have worked loose, but this was more of a problem on the mid-80's models.

FWIW, the clock in my wife's '93 is on the same circuit as the dome light. Don't know about your '99 but that might be worth a look. Is your dome light working? FWIOW YMMV DFB

Yes, my dome light is working. I don't remember offhand if it's on the same circuit as the clock or the flasher indicator light, though.

Yes, I have checked every fuse associated with the clock (according to my manual), and they all seem to be fine.

This was my thought. I was fiddling around in there where the radio is a while ago (I was taking the radio out), which of course isn't too far away from where the flasher indicator is. It's possible that I inadvertantly disconnected a wire or something.
