About a year ago I had to roll the dash light dimmer dial all the way up to keep the dash lights on, however about a week ago the lights stopped working. A couple of times I've heard a click and they come back on, only to disappear a little while later.

Any idea what might be causing this? A few of the lights in the stereo buttons haven't worked for a couple of years, not sure if that has any impact on the issue.

Thanks for any insight.
