Steering Wheel Controls

How to do I go about checking that? I am trying to check things myself to avoid taking it to the dealership.

Do they usually charge for that or just check it to see if that's the problem? Do you know about how long that takes to check?

Is that the device you plug into the fuse box? The diagnostic tester?

My radio buttons on left side of steering wheel won't work but the right side with the cruise control work fine HELP ME

Having similar issues.....RIGHT side of my steering wheel (cruise control side) not working at all, the horn doesn't work, Air bag light is on, cannot reset my mileage settings...don't want to have to take this to the dealer anyway to fix it myself?

EVERYONE - HYUNDAI HAS EXTENDED THE WARRANTY ON CLOCK SPRING ON SONATAS TO 15 YEARS. GO TO THE DEALERSHIP AND GET THIS FIXED. ALL YOUR STEERING FUNCTIONS ARE RELATED TO THAT CLOCK SPRING ISSUE AND IT IS COVERED UNDER WARRANTY.

GuruKNKZH, are you positive it is related to the clock spring? The dealer is going to charge a $125 diagnostic fee unless they can determine it is the clock spring. I just am curious why the clock spring would allow the left side buttons to work fine but the right size to not work.

I am at the dealership right now. Nothing right side of my steering wheel works and the horn doesn’t work, they’re trying to screw me around and say it’s a bad horn .

Clock spring

I actually just had my clock spring replaced along with the knocking engine swap. The job they did apparently did not fix my button issues. I'm thinking it may be related to a wiring harness failure behind the clock spring, but I do not know how to access it. Now (started a week after the replacement) my airbag light is always on so I need to get it back to then. As for the left side radio buttons, I just swapped my radio and can say for certain that those buttons are a different circuit altogether (I don't know if they travel through the clock spring too or not) but it's a 2 wire circuit that connects to the radio harness and directly to the radio. If you have an oem radio i can't see how it would ever fail but if you have replaced your radio then most raise need a special interface to make these buttons work with after market radios (search for maestro sw or rr). Some radios can take the wires directly in without the separate interface and read the resistances if the different buttons. If they stopped working and you didn't replace the radio then the wiring behind the steering wheel and/or clock spring might be to blame for that, I would think. Oh also I found that in order to make the left buttons work if I hit the steering wheel like I'm hitting the horn, on the right side of the horn pad near the buttons (or quickly hit the horn) with moderate force it'll make the buttons work already for a little bit. Definitely bad contacts between the buttons and control circuits, actual fault is within the steering wheel components.

Correction... They changed my mdps flexible coupling, not my clock spring! After doing some more research I just learned that the clock spring is the actual rotatable wiring assembly that connects steering wheel electrical components to the non-moving side of the assembly. This is definitely my problem and if your reading this then it's probably yours too!
