Crusie control does not work on 2011 gmc sierra 1500 and I've already replaced the switch?


If the switch is replaced,then it can be wiring issue or faulty cruise control board.But as the switch is replaced,get the voltage at the switch tested to confirm the switch is actually receiving voltage.If no voltage received at switch power supply wire then ,apply external 12 volt power to the cruise control switch wire and then see if cruise control comes ON.If yes,then you know wiring is issue.

Brake lights won't come on after changing brake booster on 97 gmc 1500. Also won't shift into gear.


check for a bad brake light fuse! if not the fuse, the brake light switch operates brake lights and if bad you will not be able to shift it out of park, as well as the brake lights not coming on.! because you have to put foot on brake to do so. if bad switch, it wont let it out of park. it could be just out of adjustment also!! good-day !
