DIY: Blower Motor Fix
 

It's an old trick, but, still works.
If your blower motor squeaks or sounds as if it's just all it can do to spin.
Remove it and drill a 1/8" hole in the nipple looking part of it. (center of the back side, where the end of the shaft is).
Add a couple drops of oil, spin it by hand, add a couple more drops.
Then, with it in your hand, connect it back to power and see if that cured it.
If so, seal the drilled hole with a dab of rtv silicone and re-install.

When/IF it acts up again, no need to remove. Just clear the silicone, re-oil, and re-seal.
Use something heavier than wd-40.

Redlinear= Good info. LPS-3 would be a better choice then WD-40.
Thank you.

Correct. Don't use wd-40 or anything thin like that. I've always used simple 3 in 1 houshold oil. (due to always having a little can of it handy. AND, most importantly: Those little cans have a litte nozzle that fits that 1/8" hole just right)
