It is changing time but I'm not sure if the button is simply jammed from age? I tried a skinny allen wrench and it definitely goes in the hole. However, I have pushed it in hard enough that my finger really hurts. I imagine it can't be that much pressure to change it. Does the key have to be in a certain position? I tried it while I was driving and again when the key was off. Does it need a new clock? Like I said, it works, just doesn't adjust time.
Thanks for the quick reply and any other advice!
Got it! I tried it again knowing that this was the right button. I guess it's just finicky...
Thanks for the help!
