I’ll admit off the bat that I did something terrible. My wife’s battery died last night, and in an attempt to jump start it, I crossed poles. The casing on the cables started melting, there was smoke. I quickly disconnected the cables when I realized what was happening. We have since had the battery replaced in the car.
This is a 2010 Chevrolet Equinox.
What remains is what’s seen in the attached image: a series of columns of dashes scrolling through the screen. Looks like The Matrix! Additionally, the speakers make a popping sound every 5-10 seconds. I removed the fuse for the radio and replaced it with another, same result. Removing the fuse does stop the popping sound in the speakers though, which seems obvious. Incidentally, this behavior persists after the ignition is turned off, it’s just that the display is not back-lit.
Obviously, I’ve messed something up. Is it possible that simply replacing the control panel that contains the display along with all the controls for the hvac system would suffice? Or have I ruined something else?
