| - | [* black] 10. Remove the four 5/16” screws that hold the blower motor assembly in the housing and gently pull the motor assembly free from the housing. Note that there is a foam gasket between the motor flange and the duct housing. Also note the orientation of the flat edge of the flange. It faces the outlet of the housing. |

| - | [* black] 11. Remove the metal pushnut from the blower motor and wheel assembly. I used a pair of needle nose pliers. The pushnut will likely be destroyed during removal. The replacement motor should come with a new pushnut. |
| - | [* black] 12. Separate the wheel assembly from the blower motor shaft by gently prying between the two with a suitable tool. Carefully pry around the two until you can slide the wheel off the shaft. Note that the shaft has a flat side that keys to the wheel. |
| - | [* black] 13. You may want to clean the ducting and wheel at this time. I used Clorox wipes for the inside of the ducting and a mixture of bleach and dish soap for the plastic blower wheel. |
| - | [* black] 14. You may test the replacement motor at this point by taking the two motor power leads and connecting them directly to a suitable 12 VDC power source. The motor is reversible, so the polarity doesn’t matter. I simply touched them to the car battery terminals. Note the rotational direction of the motor. In my case, the blower wheel must spin counter clockwise (CCW) as viewed in the installed position in order to move air. Ensure you make a note of which motor wire needs to be connected to the positive side (+12VDC) and which wire needs to go to ground. My blower fan (CARQUEST PN 208988) required the motor orange wire to go to the harness black wire and the motor black wire to go to the harness orange wire. Don’t just assume that you can match the colors and it will be wired up correctly. |
| - | [* black] 15. Install the blower wheel onto the blower motor shaft by matching up the flats and pressing it into place by hand. Once the wheel is fully inserted, secure the wheel with a new metal pushnut. |
| - | [* black] 16. The replacement motor did not come with a foam gasket and the original is likely permanently bonded to the original motor flange. Apply some Permatex black gasket maker (or equivalent) around the motor cutout and gently slip the replacement motor and wheel assembly into place. |
| - | [* black] 17. Install the four 5/16” motor flange screws into the housing and tighten them. Do not over-torque these, as they only hold into plastic. Once this is done, spin the blower wheel with your hand to ensure there is no binding or clearance issues with the housing. |
