97 A6 2.8 Dash Gauges Not Functioning
 

The following Gauges on the dashboard are all dormant - do not fluctuate - just sit at ZERO;
1. Speedometer
2. Oil Gauge
3. RPM Gague
4. Temperature Gauge

This occured after making adjustments to the seat and mirrors while the car was off. Upon starting the car!! No gauges work except the analog clock. Any suggestions on what may be causing this.
