It takes 10 minutes to take out the gauge cluster... pull it out and run a new ground from each ground on the cluster to the nut that holds the right side of the dash on (it's a solid ground).

You can do it, give it a shot.

If that doesn't fix it, it's not a ground, but if it fixes it, you owe me a beer if i ever come to Cali <img src="/forums/images/graemlins/notooth.gif" alt="" />
