I have a '02 Civic EX and have two questions.

1. Last week the light for the air mode control was not light, it was
like that for a couple of days. About that same time I heard some
buzzing noises comes from the panel--the sound was intermitent . . not
constant.  Also heard it when I went to start the engine once.
The light is back on now, but have heard the noises a few other times.
Any idea what the problem might be?

2. The lights for the AC and recirculation have been out for some time
now but those features work fine. Is that a fuse that needs to be
replaced? Checked the fuse box and didn't see a fuse for these
components.

Any one have any idea what the problem(s) might be?

Thanks!!
