I have the same problem with the Carabc backlight staying on after the truck has been off for a while. You said you have a fix for it and to reach out. Well, here I am lol

My battery has been slowly draining for no reason known to me, until last night I noticed the backlight was still illuminated hours after I turned the truck off. Perhaps maybe we continue the conversation in the forum for others to find and fix the issue on their own?
