SOURCE: rear wiper motor reaplacement needed 2002 Chevy Trailblazer

use a medium size flat head screw driver and only pry up where there is an clip. there should be quite a few on the back hatch. so if you do break one or two it will still hold together well. and be sure when you change the motor to mark the splines that the wiper goes on so that when you reassemble it the wiper will go all the way across the window and return all the way back down.

SOURCE: 2002 Trailblazer blower not working

The blower motor resistor card is located under the glove box. You have to take the bottom panel from underneath the glove box out(be careful not to break the wire clip that holds the wires in place on that panel). Once you take the panel loose look in the back. You will see the blower motor. Behind the blower motor is the card. You will need a 9/32 for the panel and a 7/32 for the card. It is only 4 screws total to remove and 2 wire harness clips. It is about a 15 minute job. Good luck and hope this helps.  Auto Zone has the part for around $15.00 and will have the step by step instrutions for you also if you need it free of charge. I think the dealer charges $109.00 for this repair.

SOURCE: I need to remove the interior panel on the driver

You'll need to remove screws that are by the door handle, arm rest, under door and side of door and then gently pull back on the panel as there will also be retaining clips attached and you don't want to break them. You'll need to lift the door panel upwards in order to get it off the window ledge. then you can pull back the weather seal (can't reuse it, but it's not that important) and you will be able to access everything inside the door

SOURCE: The temperature display on the rear view mirror shows OC

The temperature display on the rear view mirror my 2002 Trailblazer LT is either way incorrect - like obviously too high or too low - but mostly just shows "OC" all the time. Is this an expensive fix? Is this an easy fix that I could do myself? What do I need to replace and how

SOURCE: I need to know how to remove rear door panel

On the inside trim, you can remove screws that are by the door handle, arm rest, under door and side of door and then gently pull back on the panel as there will also be retaining clips attached and you don't want to break them. You'll need to lift the door panel upwards in order to get it off the window ledge. Then you'll need to manipulate the panel and disconnect the door handle linkage from the door handle and disconnect the wiring for your controls. I don't know what speaker you'll actually need.

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.

Problem with dual zone heating only one side i check control thermost botton is ok


Sounds like the blend door actuator. It separates the driver and passenger side from getting air on the AZC system. Here are some instructions on replacing it:
The passenger side blend door actuator is used on all models equipped with Automatic Zone Control (AZC). This actuator is located on the front of the HVAC housing to the right of the floor panel transmission tunnel and cannot be removed from the passenger compartment without instrument panel or HVAC housing removal.

NOTE: This procedure is for AZC Systems (Passenger side only).

  1. Disconnect and isolate the battery negative cable.
  2. Remove the glove box door. See: Body and Frame\Interior Moulding / Trim
  3. Remove the lower I/P glove box door surround panel.
  4. Remove the dash assembly. See: Body and Frame\Interior Moulding / Trim\Dashboard / Instrument Panel\Service and Repair\Instrument Panel Assembly
  5. Remove the HVAC assembly. See: Housing Assembly HVAC\Service and Repair
  6. Unplug the wire harness connector from the blend door actuator.
  7. Remove the 2 screws that secure the blend door actuator to the HVAC housing.
  8. Remove the blend door actuator from the HVAC housing.
INSTALLATION - AZC (Passenger side only)


  1. In stall the blend door actuator on the HVAC housing and tighten the two mounting screws to 2.2 Nm (20 in. lbs.).
  2. Plug in the wire harness connector to the blend door actuator.
  3. In stall the HVAC unit into the vehicle. See: Housing Assembly HVAC\Service and Repair
  4. Install the instrument panel assembly into the vehicle. See: Body and Frame\Interior Moulding / Trim\Dashboard / Instrument Panel\Service and Repair\Instrument Panel Assembly
  5. Evacuate the HVAC system.
  6. Recharge the HVAC system.
  7. Connect and the battery negative cable.
Hope it helps! If you need more, just send me an email at familyguy77351 at yah I wil be glad to finish helping you with more detail.

Not having any heat there is aclicking sound when i turn controls to heat


you have a A/C-Heat blend door actuator malfunction. This door switches from A/C vent to heater core vents via an actuator motor.Very Typical problem on Ford/Mercury/Lincolns vehicles. There are multiple actuators in this vehicle, some in the dash and some in the rear (only if equipped w/rear A/C-Heater. This will require pin pointing the exact fault, and may require lower dashboard or rear quarter panel interior trim (if rear A/C-Heater equipped) removal

2001 Pontiac Montana Rear heat blows only cold air???


The rear temp blend door is stuck in the cold position ,very common problem on vehicles with rear HVAC units . There is no valve , electric actuator !
Air Temperature Actuator
The air temperature actuator is a 3 wire bi-directional electric motor. Ignition 3 voltage, ground and control circuits enable the actuator to operate. The control circuit uses a 0-12 volt linear-ramped signal to command the actuator movement. The 0 and 12 volt control values represent the opposite limits of the actuator range of motion. The values in between 0-12 volts correspond to the positions between the limits.
When the HVAC control module sets a commanded, or targeted, value, the control signal is set to a value between 0-12 volts. The actuator shaft rotates until the commanded position is reached. The module will maintain the control value until a new commanded value is needed.
