The speedometer on my 2004 Envoy has died. How do I remove the instrument panel on a 2004 Envoy?

GM went to electronic (as opposed to mechanical) speedometers many moons ago, so your most likely culprit is either the sensor unit at the transmission or the wires to the speedo, or (as happened to me) the gear in the trans that drives the sensor is bad (I had to pull the tailpiece on my '91 Corvette to replace it)...the speedometer itself could be bad, too, but that's not very likely...

Duplicated question

More than likely the stepper motors that drive the gauges are going bad, this a common problem on these instrument clusters. There are several repair services listed on E-bay who repair clusters, if you are willing and capable of removing it from the vehicle.

if it auto transmission , the ratio changes and the speedo reading is affected by the VSS sensor ( around $100 from reports)
if the transmission is running well other than that it will not need a transmission just and transmission oil change
suggest that you find an accredit professional transmission shop and have a proper diagnosis done

Pretty common problem with these. Here's a guide to learn how to fix GM instrument clusters yourself, I used it to fix mine and it worked great.How to guide for Envoy instrument cluster repair

That is a manufacturing defect associated with your instrument cluster. My local dealer replaced my entire instrument cluster for free (truck was out of warranty) when my speedometer showed 100 mph in a parking lot and my oil pressure gauge read 0.

There is a recall on the panel Cluster... call your dealer and have it checked out.. mention the recall... www.lemonauto.com

This issue is caused by faulty motors inside your Envoy instrument cluster and can only be repair by taking out the instrument cluster and replacing the motors which requires de-soldering and soldering tools and the correct replacement parts.
