Hello. I am trying to help a young friend who just purchased a 2006 Impala with 130,000 miles.
All dash gauges worked fine for first couple days - except erratic speedometer. Shortly after we changed the gas pedal and heater blend door motor, all the dash gauges went dead.
The dash lights still work. If we disconnect the battery and then reconnect it, the gauges all work fine until after you turn the key off. After that, they die again and stay dead unless you unhook battery.
Any thoughts on how to fix? I know speedometers have issues in these cars, but the other gauges work fine (when they work).
