2009 Chevy Silverado 1500 cruse stoped working but light is still on.

This is very complex , first thing is have the vehicle checked for DTC'S - diagnostic trouble codes stored in the BCM , PCM !
The body control module (BCM) monitors the signal circuit of the cruise control switches. The BCM relays the cruise control switch status to the engine control module (ECM) via the GMLAN serial data circuit. The ECM uses the status of the cruise control switch to determine when to capture and maintain the vehicle speed. The ECM monitors the vehicle speed signal circuit in order to determine the desired vehicle speed. The ECM uses the throttle actuator control (TAC) motor in order to maintain the vehicle speed. For further information on the TAC System, refer to Throttle Actuator Control (TAC) System Descriptionfor the 4.3L engine or Throttle Actuator Control (TAC) System Description for the 4.8L, 5.3L, 6.0L, 6.2L or 7.0L engines.
Your best bet would be to take to the dealer !

How can i get my silverado cruise control to work?

check your taillights as of 03 there is a circuit board under the rear of these trucks that tell the ecm engine control module if the taillights are functional if one of the bulb sockets has a bad connection or if a bulb is partially burnt or if someone has tampered with the wiring like using the wrong plug on to tow a trailer ,the ecm will not allow the cruse control to function

Cruise control

this is happening because once you shut it off you are sending an electronic signal to transmission and it resets itself once car starts back up as if something inside the ecm has been reprogrammed and erased alll over again. the ecm is your brain which controls your car. get a diagnostic scan ran on it ok?

For one i dont need your vin its a z24 which means it has a 2.4l engine it does not have an ECM it has a PCM powertrain control module, which is located for your car in the right rear corner topside of your engine bay, in 1995-2001 it is located inside the right front fender. I hope this info helps...

No it won't work. The ecm likely has all the parameters in it for cruise. Usually you just have to buy the switches and maybe a clockspring.
