Does anyone have firsthand experience in replacing the blower-motor for the heater/AC unit on a 71-73? Mine is squeaking terribly on both my Mach and my Grande.
I have heard that it is considrably more difficult on a car that is equipped with factory AC, as opposed to a non-AC car. Any hints woulkd be appreciated.------------------

That info would help me out too. The fan in my non A/C 69 rattles terribly and puts out little air.

If it's anything like my 68 with factory AC, the theory is very simple. The practice is another matter.
I just gave my blower a good clean and oiling, but my entire dash is out.
If I was attempting to oil the sucker without removing the dash (and this is on a 68, mind you), I would probably remove the center piece of the dash where there's a vent for the AC. Behind that is the main body of the vent connected to the blower by a flexible rectangular hose. With that vent in the open position, you could possibly feed a long tube from your WD-40 inside the blower fan and give it a good squirt.
Rattling is another matter though, Sportsroof, and if your system is putting out little air, it could also be that the connecting hose is bust or poorly connected.
