Does anyone know where to find a working radiator fan motor for 1984.. with A/C
/

I am in that spot as well.

3 of the magnets in my motor de-laminated from the case are were rubbing on the winding. As long as it is not TOTALLY destroyed, it IS possible to rebuild them, as i am doing with mine. If that is the route you are going to take I can post pictures of how the unit comes apart.
Another option is to just get a later year single speed fan and housing and put it in.

I will probably do this in my 84 when my fan finally dies.

But there are a lot of bone yards in Michigan that have a few fieros that you can probably find a good used stock fan.

2002 Audi Allroad. Tip. 100% Natural. (FOR SALE)
2011 VW Golf. (Wife's Wheels)
2002 VW Jetta (FOR SALE)
1984 Pontiac Fiero 4 speed Duke.

Several option depending whats wrong... If you don't care about showing the car in Factory class even more.

Resistor itself is still made.
Use later single speed (need the power socket) then wire as 2 speeds or 1 speed.
aftermarket.

I have one....

If I do go aftermarket what size fan should I get amperage and airflow wise?

I just purchased a non-running '84 w/AC. What are you talking about? Doesn't the '84 take the same fan motor as all the rest, if not why not? Can the whole fan assbly be replaced with a later model? The person I got the car from parked it because it kept overheating and he could never get it fixed. Ogre-read your link. 2 speed fan in '84 AC's.
