I'm going to have to check that fuse. I have a 2003 Grand am and I just replaced the ignition cylinder because the same thing was happening to me. But I replaced it and now I have nothing on my dashboard or windows won't go up etc. I checked the two of fuses that say ignition but I did not check that big one.Turns out there is a common fuse for those . It was a maxi fuse under the hood . 60amp . Number 3 I believe. Replace it and it all works . I’m still concerned as to what the cause is but it’s working for now at least .
