1.) Start by cleaning out the glove compartment and get your self a stool to sit on outside the car with the front passanger door open.

2. Have a 1/4 inch drive set as well as a 5.5 mill socket. Be sure to have a trouble light.

3. Open the glove box door and remove the cable on the left hand side. Do not break it. You will need to pull the tab on the outside and slide it through the opening. The door will come down and might even fall roight off.

4. You will be looking at a the blower motor. It has a cover on it which provides insulation and sound deadning. Push on the bottom of the cover with your right hand, and pull the bottom of the cover off the tab that holds it in place.

5. Pull the two wire off. The black is negative, the other is the power. push the wires aside. to allow you to pull the top of the cover off the tob tab.

6. Side the cover off to yhe left and down. It will be tight, but it will come off exposing the blower motor.

7. You will need to use the drivers to remove the hex head scews. You will need a driver for one of them do to the tight space. At this tme also remove the small hose between the blower motor and the air chamber.

8. The blower motor will be free. Simpley pull it out and rotate to get it out around the dash frame. This is a good time to wipe out the air box with a clean rag.

9. You may need to remove the grouning tab by taking the screw out. If your new motor does not have the tab, simply place the old on on the new motor. The hole should be there in the same location as the old one to receive the screw.

10. Put the new motor in the opposite way. You will have to rotate it in place to clear the dash frame. You may also need to cut the end of the little hose to fit over the new new port if it is equiped with one.

11. It took me about 1-1/2 hour including time for a sandwitch.

12. I also removed the right vent which was not required. Be careful with that vent because it is integrated with the small panel below it. The small panel has one screw to remove and then you lift the panal up. It has three slots which hold it in place, so be sure to raise it. Do not pull it.

13. It was not a very difficult task. Good Luck, and take the time to place some soft material around the dash edges to get rid of the squeeks in the dash.
