Hello I just bought a 2001 gp gt the other day. Everything works except the dic. Traction light comes on and works fine. All the other lights in the dic don't come on. It does have a aftermarket head unit but would that cause the whole dic to not work? Also when the sunlight hits dic I can see everything but it's showing all 9's and stuff. Like it just simply isn't working. Not sure if I should just try changing the light bulbs inside it first then go from there. With that being said anyone know the size light bulbs that into it? And what do I gotta do to remove the dic. And if that doesn't work is it hard to replace it with a New one?
