Recently purchased a Saturn SW2 Wagon, 2002. The speedometer, odometer, gas gauge do not work. Sometimes when you stop the vehicle the lights will not shut off. Also, sometimes you can not get the car out of gear. We have tried replacing the communication module with no success. The dealership was unable to run a diagnostics claiming a communiction error.

Any suggestions are appreciated :-)
