The fan motor in my '84 has started making a god-awful noise when it is on. Speeds 2 and 3 are the worst and I just can't take it anymore!

It makes a high-pitched "warbling" kinda noise like a worn out bearing. I'd like to replace the blower all together, but I'm not sure how.

Any tips? Thanks!

Just open the hood, lean in past the brake master, the motor is right there on the firewall, is held in my about 7 screws.
Disconnect a ground wire and a plug and pull it out.
If you get a new one it may or may not come with the fan blade. Be carefull if you switch them, plastic and can brake.
It a 15 min. job most times...
As long as the 84's are the same as all the rest...

Im not sure whitch fan your talking about?The radiator fan,the AC fan or the alternater fan in the trunk...???Because you say "Speeds 2 and 3" I'll asume your talking about the radiator fan,there are about six screws or small bolts, holding the fan motor on,use a mirror to see them.

I think your brain flipped a bit..you were thinking blower motor fan and typed radiator fan.

I replaced mine hoping for more air and it didn't improve much. Sometimes there are leaves and other crap embedded in the evaporator that make the fan work harder resulting in the noise. While the fan is out try to clean the evaporator. You can get a flexible vacuum cleaner hose in the hole but be careful the evaporator is made out of very thin metal. If you poke a hole in it, your ac will vent refrigerant all over the place, (assuming there is any in there).

And it's worth pulling out the fan speed resistor (two screw over to the left farther) and checking if there are any leave and junk there. Good place for a fire to start...
