2004 Chevrolet Avalanche 2500 Question: Speedometer is not working? Do I need to go to Dealer to get repaired?

The speedometer repair on your 2004 Chevrolet Avalanche may still be covered by an extended warranty from GM. Please check to see if your Avalanche is still covered. If not there are some aftermarket companies who repair these GM clusters please use the following link for an example on one - http://bit.ly/8z7rcm.

This is very common on the 03-06 GMs. The cause is the motors behind the gauges are failing, they all go out eventually. You can get it repaired here - www.drspeedometer.com and there's a DIY guide here - www.howtorepairmyinstrumentcluster.com
