Where are the vacumn hoses located on a 2005 chevy trailblazer in relation to the cruise control on a 4.2 vortex engine
in relation to the cruise control ????? There is no vacuum used for cruise control on your vehicle . Your vehicle has a computer controlled electronic throttle system .The powertrain control module (PCM) monitors the signal circuits of the cruise control switches in order to determine when to capture and maintain the selected vehicle speed. The PCM uses the throttle actuator control (TAC) module motor in order to control the vehicle speed. For further information on the TAC system, refer to Throttle Actuator Control (TAC) System Description .
Your best bet , take it to a qualified repair shop. Need a factory or some other professional type scanner to check for codes an data input from the switches to the PCM
