Electrical problem 4 cyl Front Wheel Drive Automatic 49000 miles

Last night out of nowhere my turn signals stopped working. I noticed it after getting in it to go somewhere, it didn't happen while I was already driving.

None of the exterior front or back light bulbs work and the interior blinkers don't work either. The head lights and interior dash lights are worked by the same controller and those work fine. Could this be from a blown fuse? If so what size do I need for the car and how do I know which one is for the fuse to change it? I'm guessing the fuses are located in the most uncomfortable & inconvenient spot to get to which is the floorboard area by the pedals.

Test fuse # 1 (10-Amp) located in the relay box of the passenger compartment. If fuse is OKAY, suspect faulty tail light relay.

Here is a guide and some diagrams (below) to help you check out the problem.

Electrical problem
2005 Hyundai Elantra 4 cyl Two Wheel Drive Automatic 49,800 miles

While driving today, I went to turn on my turn signal and I heard a bunch of weird clicking and then they wouldn't work. They don't come on in the dash or the front or back of the car. I was told maybe to check the fuse in the passenger side fuse box but I don't know where to find that. From what I have been told, this is an electrical issue more than likely and replacing the fuse won't fix it. Any help would be much appreciated! Is this something I can fix on my own?

Would suspect faulty flasher unit, it is located in the passenger compartment relay box (under left side of dash, behind passenger compartment junction block).

My elantra blows the turn signal fuse as soon as you turn the ignition on. I replaced the turn signal switch with a factory from dealership part and then replaced the fuse. This did not fix the problem. I also have no reverse lights. All the bulbs in the car are original and no wiring work has ever been done to the car. Could you help me with any ideas were I can look to fix this? Thanks

Have you checked the light sockets to see if any are melted and causing a short?

Hi there,

our turn signals sometimes don't work. Sometimes they do for periods and then sometimes they don't. When we press the signal rod on the steering column no lights flash on the dashboard and there is no click sound. I have checked all the fuses and they are fine and the bulbs are fine too. Any help as to what it could be hugely appreciated.

Fuses good parking lights work four ways work, but no left or right turn signals.
Replaced right turn signal light ghar t socket by cutting wires and re-splicing new plug in assembly for light. Had left turn light before that. Now no left or right turn lights.
Checked all fuses I could all are ten amp. Wonder if there is another fuse or breaker?

See picture and check multi-function switch to see if power is going to lights also if coming in. It may be the switch also, check fuse three it can also be hazard switch as that is the flasher unit. Check ground on tail lights as well, but it kind of sounds like switch is bad for turn signals.

It still cold be the hazard switch as well replacing parts and not knowing anything about cars is the wrong thing to do. Have a pro look at it to see why power isn't transferring from fuse/relay and switch. I assume your bulbs are ok.

My turning signals will not work at all. They dont flash inside or outside of the car. I dont know what to look at or how to fix it. I believe it could be a wiring problem.
