A friends car, 96 B4V. Radiator fans ran all the time. Then speedo quit working as well as wonky fuel gauge. We found a ground up gear on speed sensor in transmission and replaced it. Still no speedo. We swapped out the cluster and no difference. Cleaned up all the grounds including the three near the head. While doing all this, the fans quit running all the time. Any ideas on common wiring between the two or other things to check. Cruise does not work, so signal from VSS is not going to anything. thanks
