You get at the blower from outside. Raise the hood to full vertical position, remove the windshield wiper motor and the grill below it.

If you have the same CD as mine, you should have the R&R instructions if you keep hitting the arrows under the Climate Control section. Failing that, there is a very good thread buried in this forum with pictures and very good instructions. Do a search of Blower Motor Replacement or something like that. It is likely that the motor is frozen or has worn brushes.

Good luck,
