Ok so I am an issue with my cluster. My speedo and odo do not work at all. My tac jumps around and doesn't rise and fall smoothly and my trip odometer moves but it is very incorrect. It will move maybe 1/10th of a mile for every 20 to 25 miles. Any Ideas on what it could be. I have checked my VSS and the gears in the back of the cluster and then replaced both. Is the cluster bad or is it something else. Thanks for the help.
