The blower motor should be held in by two or three screws. If you look up from below glove box, you should see them. You will need to remove the mounting screws which hold the blower motor in place. Do this by using a small, slotted screwdriver, or a socket and ratchet from your 1/4-inch drive socket set.

Pull the blower motor out of its housing with one hand. Make sure you do not just let the blower motor fall, as you may sever the two electrical wires leading to the blower.

5
Set the blower motor mounting screws into a small cup or canister so that you do not lose them while moving around in your car.

6
Holding the blower motor securely in one hand, remove the two electrical wires from the side of the blower. Make careful note of the position of the wires on the old blower, so you can mount the new blower exactly the same way.

7
Attach the wiring to the new blower motor. It is essential that you wire the new motor exactly how the old one was wired.
-
8
Reinstall the blower motor in the reverse manner from which you removed it. Tighten the mounting screws only to the point where they are snug. The screws do not have to be extremely tight.
-
9
Reconnect the positive battery wire to its terminal.

10
Start the vehicle's engine and turn on your fan switch to the lowest setting. Go through each of the fan's switch setting until you are at max speed for the fan, to test the new blower motor.
