The instrument cluster on some 2000 Cavalier and Sunfire models may appear to be dead, with no movement from the gauges and a nonfunctional odometer. This condition may occur when the battery has been disconnected, or if the vehicle has a dead battery and is jump-started. Do not replace the instrument cluster to correct this condition. The cluster's micro-processor resets before the crystal stabilizes, causing the processor to lockup, when there is a loss of power. This lockup condition can be corrected by removing the fuse marked "CLSTR" (circuit 1440), waiting approximately one second, then reinstalling the fuse. The fuse panel access door is on the left side of the instrument panel. Once the fuse is installed, the cluster should reset with the gauge needles vibrating at their zero positions for about two seconds. The body computer also will reset. For the 2001 model year, a power-on-reset chip will be added to the instrument cluster.
