My car will run for a little while and I'll stop at the store or something and go to turn it back on and the gauges won't work. The gas, mph, and heat gauges are the only ones that won't work. everything else electrical works on the dash. It's started doing it recently and it's done it 3 times within the last few days. Please help, thanks!

    Customer Concern: The dash gauges are not working.
    Tests/Procedures: 1. Check to see if the instrument cluster will perform the self test. Begin with the ignition switch in the Lock position. Hold down the trip reset button until the word "Sof" and a number appear in the odometer window. If the cluster will not self test, then it is a possible cluster failure.

    2. Using a compatible scan tool, try to communicate with all the modules on the vehicle to see which ones are working and which ones are not.

    3. If unable to communicate with any modules, start unplugging one at a time until the communication comes back. The module that is disconnected last is taking down the bus circuit. Replace that module.
    Potential Causes: Malfunctioning Bus
    Cluster Assy
