Having an issue with the steering wheel menu buttons changing the radio volume instead of scrolling through menus and sub menus. Everything was working normal and until it wasn't, no other known electrical issues except my paddle shifters are nonfunctional. My guess on that was shifter was replaced at some point but not coded for the paddle shifters based on previous searches. The down menu seems to work most consistently, if I get to the radio menu the buttons seem to function correctly and change the stations etc.
I realize after watching the video i could have done a better job showing the issue, but i think you can tell what I am saying from it. FYI, the malfunction is washer fluid level, still chasing that leak periodically.
I don't know if this would be a clock spring issue as it works in the radio function and the buttons react/change volume? Seems like some kind of communication error, is there something I can reset?

Hello, are you using aftermarket headunit? If yes, it should be connected to CAN system. It could be the problem. Try to disconnect and then try buttons.
Factory headunit. Actually noticed yesterday my cd changer is working. It was previously working then stopped reading discs for a while and i have assumed bad magazine. Not sure if somehow related but info couldnt hurt.
Is there a way to rest the radio? I tried holding power a long time and nothing happened.
Well a few days ago my steering wheel controls started working perfectly normally and it was great... This morning I am back to the same issue as the original post. NO idea what to do.
Could this be an issue with steering column module? has to be some kind of communication issue. weird its intermittent and buttons do something all the time even if its the incorrect function. Tried to play around moving the steering wheel location to see if I could get anything working but didnt change anything with car on. Seemed like it mihgt have with key in position 2 but it has acted differently in that position anyways.
