I remember when my key fob stopped functioning to open and lock my doors. I didn't know why, until one day I discovered that these fobs are battery powered. All I needed to do was change the battery, an answer I discovered only by accident. (Mentioned it in passing during a conversation with a friend.)
There are other kinds of niggling annoyances that aren't so common. For example, what happens when your radio won't turn off? That's what happened to a fellow with the handle Rescue7 who shared this problem on the Duramax Forum. He described his issue like this:
Recently on my 07 GMC 2500 HD Classic, my radio doesn't turn off when I stop the engine, remove the key & open the door - as it always has always performed in the past? Now the radio just stays on as if on a timer & will time out after 5-10 min.
As you can imagine, he says he doesn't like walking away from his truck while the radio is still on. And I can't blame him.
Fortunately, a former GMC tech named GMAXfirefighter stepped up to the plate to help him walk it through. First, he needed to get the specifics of what was going on. After a series of back and forth posts, there were enough clues to zero in on the real issue and a solution was found.
Ugh. Fortunately, it's not only the Internet of Things that has been getting connected, but people can get connected as well, through forums and other online communities. In short, if all this high tech occasionally leaves you frustrated, you're not alone.
But solutions aren't far away either. We have a list of forums and other resources here in the right hand column. Links to forums are below, or you can just reach out and Ask Jake. If he doesn't have an answer, he'll point you in the right direction.
