SOURCE: need to recalibrate the actuator pulling out the hvac fuse b for 10 second

THE HVAC B FUSE IS LOCATED IN THE FUSE BOX UNDER THE REAR SEAT. IT IS FUSE 36. CLEAR ANY CODES FIRST. REMOVE THE FUSE FOR 10 SECONDS, REINSTALL THE FUSE, START THE ENGINE, WAIT 40 SECONDS FOR THE ACTUATORS TO RECALIBRATE.

SOURCE: where is the coolent control sensor located

2.2L & 2.4L Engines

  1. Turn OFF the ignition.
  2. Drain the coolant system to below the ECT sensor.
  3. Disconnect the engine coolant temperature (ECT) sensor electrical connector.
  4. Carefully remove the ECT sensor.
  5. Installation is the reverse of the removal procedure. Coat sensor threads with thread lock sealant and tighten sensor to 89 inch lbs. (10 Nm).
It looks like this:

Typically screwed into a coolant passage in the intake manifold or the thermostat housing.

Electronic throttle control. It's most likely a bad solenoid or sticky linkage.

Loud clicking noise from rear


If you have the EXT model Trailblazer, the clicking you hear is from the rear HVAC system and likely is one of the mode actuators trying to move a control door. The rear system is located behind a plastic panel in the rightside cargo area.

2006 Chevy Trailblazer...the top "third"


Brake light problem - if bulbs and fuses (#34 and #43 in rear fuse panel) are good, then only other possibility are the circuit boards where all the tail lights are located.

Noise coming from rear is the mode control actuator in the rear HVAC unit, it is trying to move a stuck blend door.

Where is the cruise control fuse in a 2004 chevy trailblazer?


Gotta tell you, this question had me a little confused. Below are 2 wiring diagrams for you. One is for the cruise control circuit and the other is for the air conditioning circuit. The reason I gave you those is because it seems according to the wiring diagram in the cruise control that the fuse for the cruise control goes to the HVAC (air conditioning). According to the wiring diagram for the A/C yes that fuse also controls the ignition power for the A/C controller. In any case the fuse that would cover the cruise control is the number 30 fuse in the fuse panel located under the hood of the vehicle. Below is a picture of the location of the fuse panel and also fuse layout diagrams for the 6 cylinder and 8 cylinder engine vehicles as they have different layouts depending on the engine size. I hope this helps you and good luck.
