AC Fan motor noise

The heater/AC fan in my '69 'lark Custom ( Factory AC) is noisy- I suspect a dry bearing/bush. Is there an easy fix?
I'm disinclined to drop the inner fender to remove the fan motor ( I'm a lazy man- ask my wife) so I'm after an easy way out.

Thanks from Strathpine, Australia.

 

You know the way. Only other way to keep it quiet is don't run it.

 

I've had the mounting screws come loose and cause it to make noise. While it's running and making noise, try giving each mounting bolt a 1/4 turn with a socket and see if one or two make the sound quiet up.
