My blower motor is noisy. I'm wondering if I should try to lube it or just go ahead and order a new one and avoid taking it out twice. Is it for sure its on it's way out once it begins to whine?

Try lubing it first, mine was making a very annoying squeaking/whining noise when it was cold out, I took it out, cleaned it off (it was filthy) with parts cleaner, and lubed up the circled part, and under the fan where the arrow is pointing. Good as new, doesn't make any noise at all now. I used Lucas Red and Tacky #2 grease

Thanks, mine started whining with the cold. Its not loud but annoying. I will try cleaning and greasing.

Fixed it. Easy job to remover blower, used compressed air to blow clean, lubed, reinstalled. Now it's quiet.
