Looking for some help, 2021 GMC Denali 2500. The inner tailgate open light was coming on intermittently when putting into drive. I would get out and close it and maybe the next time or next day it would happen again. After 6-8 times of this happening it finally stoped. The issue is now the inner tailgate doesn’t work at all. I have tried the trailer hitch override by holding for 5 seconds and still nothing. The full size tailgate works fine. I really don’t want to send to the dealer unless I have too.
Thanks for any input!
Scott.
