I have a 03 trailblazer and cannot find the location of the speed sensor so that I can replace it. Could you please tell me where it is located?

It's in the transmission. However, if your speedometer isn't working it's likely an instrument cluster problem. This is very common on the 03-06 Trailblazers. 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
