Since I have it the gauges work then don't work all the time. If I try to cycle the key to check for codes it won't do it. Sometimes the all work and sometimes just the tach and speedo don't work but most of the time they all don't work. I took the cluster out put another one that I have in and same thing. Sometimes when they go on the don't go to the right position either. Maybe a ground but where is the ground for the cluster?
