Clock light burned out

lighter will most probably be on its own fuse, which in your case is blown.
radio and clock will probably be on the same fuse, which has blown.
Its important to remember that most radios have their own fuse which is found at the back of the radio.(radio will have to be removed) but try the easy fuse first (in the fuse panel

replace the bulb in the overhead light. the light cover should just pull off (may be a small clip to free it, flathead screwdriver )

The CD player has nothing to do with the clock spring your player failed on its own there is no way this caused it to fail

the radio works
the clock works?
but the dimmer, park lamp in inside is burned out.?
turn the dimmer to make,
of all the other (many) park./dim lights are working then the bulbs are bad. the FSM shows all the steps for removing.
my guess, is you are asking why? above, but are you asking how?
i dont know.

the clock light doesn't have a separate fuse, it is on the same fuse as all the lights in the dash, what has happened is that the tiny bulb in it has burned out, this bulb is soldered to the circuit board inside the clock, you will need to remove the clock and replace that bulb, radio shack sells the bulb.

pull clock, radio, cd player, memory and backup cam (if equiped) to reset system. Some systems need to be recoded, not for sure about that system.

most of the time there is another fuse that shares another function such as the clock light so you cant see it, it might be on but not light up to see it, go through all the fuses and check if anything else is not working ie interior light etc. if all fails check the bulb in clock then get a multi meter to check for a power supply to the clock. im sure another fuse some where

There is a bulb in the clock but you will have to remove the instrument cluster to get to it. This involves removing some molded trim panels around the steering column and it is not very easy. Yeah, I don't think Honda could have made changing a clock light bulb any harder.

For the error code on your stereo--look in your paper work you got when you purchased the car and see if you can find a radio code in there. Check the owner's manual for a sticker with the code stuck on a page. You'll need to input the code to get your stereo to turn on. Don't have or can't find? You may have to remove the radio to get the serial number on it and call your local Honda dealer.

inside the radio is a miniature bulb that back-lights the display, this is true of all radio's, in fact they all use the same tiny bulb, these do burn out from time to time, u will need to remove the radio/CD unit and then pull the top cover off, inside just behind the display u will find a small twist in socket that contains the bulb, u can buy this bulb at any full service auto part's store for about $2

1 -Check your head light switch and turn signal switch by taping them lightly - Common problem with fords to short signal light switch/head lights and they also have radio lights/clock lights control(lights dim for Radio/clock when you turn the lights on)

If you have checked all the fuses and switchs, possible that the light bulbs have burned out. Check with a local radio repair shop and they can remove the radio and install new bulbs.

YOU NEED TO REPLACE THE MINIATURE BULB THAT LITES UP THE DISPLAY, YOU WILL HAVE TO REMOVE THE RADIO FROM THE CAR AND THEN REMOVE THE TOP SHEET METAL COVER ON THE RADIO, YOU WILL SEE THE BULB SOCKET PLUGGED INTO THE BACK OF THE DISPLAY.
