How do you replace the blower motor in a 1990 Toyota Corolla?

First try hitting it w a hammer...( this might get u by for awhile)....it's located rite bhind the glovebox.....Small dash pod removal required....Pop the speaker grille off..........its shaft runs vertical...its mounting is a 3 bolt flange...bolts are easy to get to....facing downward....use a mirror and long ratchet extension....once its free....there's a gasket to reuse...be careful....the motors are sold new....runs $60....GOOD LUCK!

In both my 89 and 90 corolla it turned out the blower fan was good. Common problem is the blower switch goes bad or gets corrosion on the contacts. I have successfully removed, cleaned and replaced the blower switch on my car and it works in all 4 positions now.
