My problem is the radio control buttons don't work, volume and selector knobs do function, and the only other buttons that will generate feedback is pressing the AS (Auto Store) and 2 buttons simultaneously, which result in the power button flashing. All the buttons also light up, but do not function.
So i've googled, and performed as much trouble shooting as I possibly can (shy of using a multimeter to probe the voltage coming from the connector that goes to the radio control buttons front assembly...because there aren't any schematics that show what it should be aside from + - and GND). I took apart the center stack, checked the cable connection, unplugged it, replugged it, no solution. Changed fuses, no solution. Unplugged #2 and # 10 ECM fuses, no solution. Unplugged the negative battery connector, no solution.
The car is a 2012 Chevy Cruze, without the digital nav option, or the chevy infotainment system. I can control then standard radio from the steering wheel controls to change source, next, back, and mute/unmute. So what should I do next? I can order a replacement button control from amazon for $40, but my googling says it's a voltage issue and the EEPROM values aren't reset to 0 and it wont solve anything, which also coincides with the AS + 2 buttons generating a flashing power button.
Can the dealer upgrade the software (it's a 2012, and I just changed the spark plugs which happened to be NGKs...so I doubt the software has ever been upgraded)? Will the special coverage for the negative battery cable solve this issue (The negative battery cable still has the factory tag with a date of 2012) if the symptoms qualify me for the coverage?
Any advice will be appreciated!
