today I was going to surprise my girlfriend with a new cd player in our 2002 suburban. I hooked it up as best as I could, it worked fine in the driveway. As soon as I backed out of the driveway, it began flashing. no sound, just flashing. Once the sun set and headlights were needed, I noticed the instrument panel lights were out. Has this happened to anyone else? Id so, how did you fix it?
