My blower motor squeaks when running at mid-range. I think this is a common problem with lots of blower motors. Does anyone know of a quick fix. I took it out. It looks fine and I tried to lubricate it but it still squeaks. There has got to be a solution short of buying a new one. Any ideas? Thanks.

I was able to lubricate mine. It's tough to get the upper bearing lubed without removing the squirrel cage or making a gigantic mess, but I managed it. Used 3-in-1 oil. The squeaking stopped until the motor died, fairly soon afterwards unfortunately, due to worn brushes.
