Which fuse controls the radio on the Elantra, Multimedia?

2004 Hyundai Elantra a real melt down (or just humor to say battery died as all do often)
most batteries never last 10 years, ever.(my 50y records me)

1. check all fuses first cab and engine bay.
2. check battery voltage running 13 to 15vdc good less is alternator is dead, (3 fuses bad makes new alternators fail too)
3. you never put the battery in backwards right?
4. you never jump started the car jumper cables backwards right?
5. scan the PCM yet, I bet it tells DTC errors, that you missed.
6. PCM means DLC ODB2 16pin port, all USA cars have 96 up.
7. what does melt down mean and doing what? IDK.

Check the fuse. If its okay there may be another fuse behind the unit (inline fuse) more common if the radio was replaced with an after market unit. Also make sure the ground strap on the radio is connected to a solid metal part of the car.

Answer 2 described my problem exactly, & solved it
in my 2006 Hyundai Elantra.
I had put the black "fuse puller" looking jumper in backwards.
Reversing it brot my radio, clock, dome lights & remote back to working.
Thank You

Open the fuse panel and take out the fuse for the radio. After about 30 seconds put it back in.

There is a "body control unit" that runs most of the interior stuff. It is up under the dash on the drivers side. For more info www.hmaservice.com ,sign up for free on the home page look for a tab labeled : shop. click on that. enter the year make and model, and start researching. this is the same info the dealer techs have access to. It has helped me greatly.

Then 1, bulbs are burned out
OR 2, the wiring is faulty.

check for any circuit brakers near the fuse box, if theres any of them reset them by introducing a paperclip in the small hole and press, you will hear a click.

check the radio wiring

Many (= not all) fuse boxes have a chart molded into the case and the fuses can nearly always inspected visually to see if the fuse element is intact. The one that services those items is probably marked as 'accessories.'  

I found that while checking my fuses that i had pulled out what looked like a black plastic "fuse puller" that was actually some kind of jumper. I had accidentally re-installed it reversed. I reversed it back to its original position and all lights, clock, radio, etc.. work normal now.
