Ok so I have a 2005 Chevy Silverado 5.3L Z71 and the speedometer and odometer quit on me, but no check engine light. So searched the internet, bought a new stepper motor replaced it and still did nt work however engine light came on before I put this in but after I ordered the part so I thought I would try it out anyways. Next my mechanic wiped out the code and said it was the speed sensor, so I went to my local Napa and got a speed sensor, however there is 3 of them mounted on my transfer case, tried new sensor in all 3 but speedometer did not work n any...please need help!!!!
