"There were a few days over the past 2-months that the
blower motor wouldnt work, but it usually came back in an hour or if I
opened and slammed the glove box. "

What you are describing are the typical symptoms of a motor with worn
out brushes. If you strike the motor casing with the back of your hand
you may find that it comes back to life temporarily.

You can see if the motor can be disassembled and the armature turned
down and new brushes installed(check with a local electric motor/
alternator rebuild shop) , or you can opt for a new motor.
