My 2005 trailblazer wont turn over and door locks dont work the relay under hood clicks HELP
Your battery is dead. Why it is dead is another investigation. Is it getting charged? If not the alternator could be gone.
Charge the battery, or if it is 6+ years old, replace the battery, charge, and then test.
If it runs ok with a charged battery, but the battery keeps running down, then it is likely the alternator or something in the charging circuit.
OK, now we know you have checked the battery. The door locks not opening and the relay failing to pull up means they are not getting enough juice. So if it's not the battery, then its something else in the electrical system. Because two completely separate systems (locks, starter/relay) are affected, it is something common to both of them. But go ahead and check the fuses anyway. Also check all electrical connections (Battery and other) for corrosion or looseness

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
