I did mine without having to remove anything. Just push car forward while it'* in park and block the back wheels so it doesn't roll back. The engine will rock forward enough to get the motor out.

Just a little trick for us cheapskates.....drill a small hole(1/8") in the end of the blower motor....just enuff to fit a snorkel tube of slick 50 into the hole...give it a few squirts....wipe the hole clean and apply electrical tape...cheap sleave/brass bearing needs a little lube every once inawhile....

I once installed remote oilers in both end bushings of the blower on a 240 series Volvo. Drilled the bushings and epoxied needle valve inflators to serve as oil tubes. Connected lengths of vinyl tubing to the inflators and ran them up to a corner of one of the dash vents. Just a couple of drops of oil each year kept it quiet as long as we owned it. The motors for those have a fan on each end and are located behind the center of the dash. Those motors cost over $100 years ago and are incredibly difficult to r&r. At the time, I could not afford a new motor, and I really did not want to have to do the job again!
You know, you may have inspired me to tear apart the old one and do a little failure analysis. I wonder if it was bad bushings or bad brushes? Maybe I can repair it for just a few $....hmmmmm

Well, it wasn't making noises like a bad bushing, and from the looks of the commutator, no amount of oil or new set of brushes was gonna save this one. One brush had worn down enough that it had lost contact with the commutator and was making the electrical connection by arcing. Pretty much ruined the commutator. This motor is toast.

Sorry bout your bad luck....I had a '79 Firebird....the blower motor always ran.....no way to shut it off! Anywho....in order to change it..you had to unbolt the right fender splash shield(which was metal back in 79)...and loosen the fender on the bottom just to gain access to the blower motor! I bought a Napa rebuilt unit with the lifetime warranty....I had to change that sucker almost yearly! What a PIA....
