On my 2002 Pontiac (http://www.carforums.net/showthread.php?t=41371#) Grand Prix SE the speedometer, tachometer and temperature gauges stopped working. I checked and the fuses and all were okay. When I turn the car on they all move as though power is being applied. I am just not getting any readings. Everything else works fine.Can anyone help or have any suggestions?

Welcome to AF.
That doesn't sound good. Check the electrical connectors at the back of the IP Cluster and make sure they are tight. Also, the 80 pin connectors at the PCM module. Other than that and checking continuity of the wiring between the IP and PCM module your problem sounds like either the IP or maybe the PCM module. All signals such tach, VSS and ECT input the PCM module before being distributed to the IP.
