      I purchased a 2021 GMC Yukon back in December and it has the rear entertainment package. I haven’t tried to use it until recently and am finding that none of the HDMI or USB-C ports are working. Before scheduling an appointment I wanted to see if it was just a fuse, however, the owners manual does not specify a fuse number for the HDMI ports. Anyone have this problem or know which fuse?

      Exact same problem. Were you able to fix this?

      No. In fact, I took to a dealership and they told me it was fixed only to get home and realize it wasn’t. Now I’m having to wait for another appointment.

      Has anyone gotten a fix for this? I am having the same problem in my ’21. Fuses for those ports are all fine.

      I am having the same issue. Very annoying because we are going on a trip. Bought a Amazon Fire Stick…didn’t work. So bought a Roku, nothing.
      I feel like I am making this more difficult then needed.

      Any updates on this. My USB-C works intermittently. Sometimes the system recognizes it, sometimes it doesn’t. Incredibly frustrating.

      I have an update!
      I finally took my vehicle in today. They discovered broken wire under the passenger side. Warranty should cover the fix.
      A little invasive (sounds like they have to tear most of it apart.) But luckily I should have my vehicle back tomorrow. Fingers crossed.
