after the TPMS issues this week. I've also been noticing that on certain channels the steering wheel volume controls dont work correctly. Pressing volume UP, turns it down. Pressing volume DOWN, changes the channel.. Any way to just reset that system? or is there more of an issue. It works fine on other channels besides just one.

 

Sounds like a short some where.


Have you pulled the wheel apart to look for a faulty connection?

 

its seemed to have corrected itself randomly after I turned car off/on
