I have had (2) online online instrument clusters of the years to repair the odometer scrolling problem on my 2004 Tahoe. As everyone in this forum knows it can be fixed but the problem comes back. Now I have it for the 3rd time. I am the original owner of this vehicle and never got a recall notice. Can anyone answer what exactly is the part that fails when this happens, where to buy it and how to repair it? I really can't afford to keep fixing this and there is only 91000 miles on it
