My car radio, over head light, and clock wont work on my 02 accent. i talked to the dealer and said i have blown a fuse but which did i blow and how can i fix it?

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 )

I HAVE THE SAME CAR AT THE MOMENT I HAVE MY DASH APART TO GET TO RMY RADIO THERE IS NO IN LINE FUSE ON HARNESS TO CLOCK RADIO. IF YYOU DONT HAVE A WORK SHOP MANUAL TO RETREIVE WIRING DIAGRAM AND SOMEONE THAT CAN READ THE CCT THEN YOUR OUT OF LUCK.
TAKE IT TO YOUR AUTO SPARK IT WILL BE CHEAPER THAN DEALER. YOU CAN OBTAIN INSTRUCTION TO REMOVE CONSOLE BY TYPEING YOUR MODLE AND CAR ON U TUBE AND YOU WILL FIND A GUY TELLING YOU HOW TO REMOVE CENTER CONSOLE PROCEDURE THATS WHAT I DID. GOOD LUCK.

It sounds like a blown fuse. Are you checking them with a test light? And have you located all of the fuses. there will typically be a fuse box under the drivers dash area, and one under the hood. have another look Im certain you'll find a blown fuse. Good luck.

you might need to look at the wires on the back of the radio, there might be an inline fuse, also you best have a look at the main fuse panel in the car and see if the one for the radio and clock has blown

it wont be an overload, more likely a short, check saloon and boot light bulbs, boot light switch, door switches, looking for a broken switch or loose wire

Could be as simple as a blown fuse for the ETACS module, but it sounds more like a problem with the anti theft immobilizer system. Does your car have remote keyless entry? And is the key you are using a factory key or one someone made? (factory key will be encased in bulky black plastic with hyundai logo) The transponder in the key might have worn out and is not talking to the car anymore. Some hyundais use the radio antenna to receive the signal, is there an antenna on the car? Is it hooked up? If it is a problem with the key and immobilizer system, It will unfortunately need towed to a dealer and reprogrammed.

Check the fuse box and look for a blown fuse. If the fuse keeps blowing, then there might be a bad wire somewhere or the brake light sockets may be corroded. That can cause problems an cause fuses to pop. Hopefully, it's just a blown fuse and and not too bad of a problem.

Check your clock and radio fuses at the fusebox if it got busted. If the fuses are intact, then you need a replacement for these items. They are damage by the
reversed polarity that happened.

the keyless entry does not have a fuse itself however the vehicle has a iod, or storage fuse, that will disable the keyless system but other accessories wont function, the dome light , clock, or radio, if those items work then the fuse is good. check the remote itself, the dealer can check the remote n/c, if the remote is ok than the relay can be bad or the alarm module, best advice, take it to the dealer, they will know whats wrong with it and it wont cost too much to diag .

you could have fried a wire take a es ligh and pull the dash apart and test were the balbs go in oher wise check check the balbs they could have went out
