Hi,
I changed my cabin air filter in our 2016 Suburban. Leaves fell down into the blower so I had to take it out to remove the leaves so it would rotate evenly. Put everything back together and closed the door (note: I did not unhook the battery while doing this). The next day, my wife told me the radio and rear entertainment was not working. When I looked into it, the Bluetooth, radio (black screen), rear DVD players, onstar button, and backup do not work. It as if they don't have any power at all. The blinker works and makes noise when in operation. I have pulled and checked the fuses for the radio and RSE in the passenger side panel, unhooked the battery multiple times, and unplugged the HMI. I have seen similar posts but the systems seem to work intermittently and it usually points to a faulty HMI. Any idea where the power comes to the fuse panel? I didnt know if there is another fuse or anything to check since there seems to be no power?

Thanks,

Drew
