Steering Wheel Controls - Not Working

Get a test light and start chasing.

 

Under the steering wheel in the column there is metal disk that connects the controls it went bad

 

The steering wheel buttons send information to the cluster (Dash), then the cluster share the command received through J-1939 to the others ecu Light Control Module and Radio.
Did you have any repair recently, steering colum joint, radio replacement ?
Your contact reel under the steering wheel can be defective without air bag fault code.
Do you have any check light ON with J-1939 DTC ?

Just to be clear did they all stop working at once? Or all buttons on each side at once? Or did they go out slowly and you can occasionally get them to work if you push hard or fool with them? I ask because mine were all gooked up from the PO and I've had to hit them with electronics cleaner a few times but they work now with a firm press.

I don't want to hijack but this may help the OP, how do you get the buttons off? Looks like each side housing would pop off but I don't want to break clips and mine won't come free easily. Pull the wheel? No screws underneath that I can see.

 

The steering buttons are connected to the dash(cluster) cannot be check with a test light.

Could you elaborate a little about this disk (I know it's been 4 years, lol) is it right under the wheel?

 

It is called a "clock spring" google or youtube for explanation.
