THE STEERING COLUMN (DO NOT ROTATE THE STEERING WHEEL AFTER THE INTERMEDIATE SHAFT IS REMOVE, YOU WILL BREAK THE SIR COIL), WINDSHIELD MOLDINGS, AND DASH HAVE TO BE REMOVED FIRST.

NO DISRESPECT INTENDED BUT IF YOUR NOT A TALENTED MECHANIC I WOULD FIND ONE OR HIRE ONE THAT CAN DO THE JOB FOR YOU. THIS IS QUITE INVOLVED FOR A NOVICE.

Yeah if you have to tap on it, then that means the brushes in the motor are worn out and you need to replace it. The blower motor is behind the PCM and Coolant Overflow bottle. If you remove these then it will give you better access to motor. You'll have to cut around housing. There should be a groove already there for you, just make sure you don't cut all the way around it. Once you open it and get the new one installed, you'll have to use caulk to seal where you cut it at.
