ATF or penetrating oil is used to lube the blower motor bearings in an effort to keep it from squealing. I hope it continues to hold up for you. At about 140,000 miles my blower became intermittent. After I had it apart a few times I finally determined that the brushes were worn and too far gone. I replaced the motor and it's been fine for the last 40,000 and going strong.

Good luck with your repair / dispute.

Experience is something you don't get until just after you need it.
