DISASSEMBLY STEPS:
1. Remove and retain the TCC solenoid.
2. Remove and discard the OEM TCC boost valve and sleeve, TCC apply valve, and spring.
REAMING INSTRUCTIONS:
1. Remove all components from the bore. Discard the TCC boost assembly, TCC apply valve and TCC apply spring.
2. Clean the valve body bore thoroughly in a solvent tank.
3. Securely clamp the valve body horizontally to the bench, making sure not to clamp directly over the bore to be reamed.

This blower motor has undergone some changes in design so the installation procedures have also changed. The original motor was a two piece motor and the wheel was secured with a set screw. GM changed the design to a one piece unit with a fiberglass heat shield and the wheel is pressed on. On some of the models you may need to remove the front cradle bolts so the engine can be rocked forward. This will help keep the valve cover from interfering with the blower motor replacement. On all models; disconnect the negative battery cable.

The intent of this bulletin is to provide technicians information regarding the proper installation of the Heating, Ventilation and Air Conditioning (HVAC) Module blower motor (with impeller) assembly.
The current available HVAC Module blower motor for the above listed vehicles can be identified by the three mounting holes (1). The original equipment blower motor had five mounting holes.
In order to avoid confusion and ensure a high level of customer satisfaction, when replacing an HVAC Module blower motor, refer to this bulletin for the appropriate procedure.

Raise and support vehicle, allowing suspension to hang free.
Remove the wheel.
Disconnect the shock absorber electrical connector.
Support the lower control arm with a jack stand or screw jack in order to relieve the spring load.
Remove the lower shock absorber nut(s) and bolt(s).
Remove the upper mounting nut(s). On some models, the upper shock mounting nuts are located in the trunk behind the trim cover.
Remove the shock from the vehicle. On some models, you may have to compress the shock by hand to remove from the mounting.

These instructions are based on my experience with removing and cleaning the throttle body and from information obtained from the 2000 Durango Factory Service Manual. They were originally my notes for use when I have to do it again. They are as complete and detailed as I can make them, however they are provided for informational purposes only and you should follow or use them at your own risk! Other year models may be different; other engines ARE different. If something on yours seems different, it may well be! Use your head and be careful.

FRONT STRUT REMOVAL
1. Loosen the front wheel lugnuts.
2. Raise the vehicle and support it on jack stands.
3. Remove the front wheels.
4. Disconect the air line fitting and unplug the electrical connectors for the height sensor and solenoid.
5. Then vent the air from the bag.
6. Be sure to mark the position of the strut at the bottom where it bolts to the spindle.
7. Remove the nuts and bolts from the strut.
8. Be sure to disconnect the brake hose from the strut.
9. Now remove the upper three nuts where it attaches to the shock tower.
10. Now dismount the strut from the vehicle.

LIGHT DISARM RESISTORS
The resistors are connected into the wiring at each wheel to bypass the original dampening solenoid so that the Road Sensing Suspension will function without giving the driver a suspension error message on the instrument cluster.

INSTALL RESISTORS
Cut the wires leading to the dampening solenoid on the strut/shock. Connect the wires to the ends of the resistor. (This is an in-line resistor so it does not matter which wire goes in or out.) Tape up both ends with suitable electrical tape to prevent both shorts and corrosion. Tie back out of way with a plastic strap.

REMOVAL OF OLD THROTTLE BODY
1. Disconnect the negative (-) battery terminal.
2. The air inlet tube connecting the air cleaner to the throttle body must be removed. Loosen both of the clamps on the air inlet tube and carefully remove it from the vehicle.
3. Disconnect the throttle position sensor and the idle speed control solenoid connectors from the throttle body. Also disconnect the EGR position sensor connector from the EGR valve.
4. Disconnect the EGR vacuum line from the EGR valve. Disconnect the throttle linkage. Loosen the two hose clamps on the throttle body coolant hoses on the EGR spacer. Remove the hoses being aware that some coolant may drain from the hoses.
5. Remove the four nuts that hold the throttle body to the manifold. Slide the stock throttle body and EGR spacer off of the four studs.
