Replace the blower motor.

Under the glove box:

Disconnect the blower motor power transistor electric connector (the transistor is far over to the left, with a curly wire coming down to it.)

Remove the blower motor power transistor mounting screws the remove the transistor.

Disconnect the electrical connector from the blower motor (slightly to the right of the motor).

Remove the blower motor mounting screws and then remove the blower motor assembly.
(there are, I believe, 3 screws; 1 just below the connector; 1 above the connector, higher up, and slightly to the left; and 1 over to the left of the blower motor)

Remove the circlip from the blower motor shaft to release the fan from the motor.

Installation is reverse.

Hope this helps you deal with it.
