all right this is a YouTube video on how
to fix a GM faulty screen if a screen
turns black sometimes you won't be able
to hear your turn signal clicking either
in my case if you actually hit the power
button that still worked and the volume
control still worked on here but if you
took the key out and open and closed the
door
the sound would still be on so the radio
would still be on unfortunately it ended
up draining the battery so I ended up
needing a jumpstart before I found out
this was even an issue but the way I
fixed this was turning off the car and
going into the fuse box and pulling this
fuse right here this yellow one that's
the one for the radio I pulled that out
I turn the car off and on hit the power
button a couple times to try and get all
the energy all of the electricity out of
the radio if there's any residual in
there and then I sat with the car off
and the key out and the door closed for
five minutes and then I started up the
car again without the fuse in it and
then whenever I turned it off put the
fuse in and then started it up it worked
just fine so whenever I turned the car
on I actually got my screen back and my
radio controls and everything back the
turn signal worked you can hear that
working the power buttons work and the
sound works on here these buttons didn't
work for me at all either so these all
work now you can hear the hear the click
going and of course we're at 36,000 853
miles which is outside of manufacturers
warranty so thank you very much GM for
that all right guys well hopefully this
works for you good luck and complain to
GM
