My 2018 Chevy Silverado was fine until after AAA replaced my battery as it had a bad cell and wouldn’t keep a charge. I watched them replace it and they did every correct (negative side first, etc).
Now my windows won't roll up or down,..ac stopped working, my radio screen is dark, only the left side turn signal works, no power door lock, no steering wheel controls…..
I checked all the fuses and nothing looks blown, I disconnected both terminals for a few hours and reconnected thinking something would reset, but no joy….
Any suggestions?
