Correct Car HVAC Blower Motor Lubricant?

I'm about to tear apart my car for the 2nd time to install a new (used) blower motor.  I want to give this one the best chance of living a long (and hopefully quiet) life.  What's the correct lubricant to use in this type of application?  White Lithium, gun cleaning oil, silicone spray, 3 in 1, etc.?

They likely have Oilite or equivalent bushings.  Here's an articile that describes how to re-oil them. https://www.nationalbronze.com/News/tips-for-using-oil-impregnated-bronze-bearings/

Thank you!

The trick is that blower motors aren't usually designed to be disassembled and serviced, so removing the bushings and soaking them in hot oil may be a process.  Let us know how it turns out.

FWIW, a few months ago the blower motor on my daily (2019 CX-3) started making terrifying noises and then seized up completely a few weeks later.

I ordered a replacement from Rock Auto for $48 all up including tax and shipping and three days later I received a nice unit that was a perfect fit and even had been balanced.

I've heard horror stories about how difficult blower fan R&R jobs can be so I timed myself...28 minutes later I was good-to-go; thanks Mazda!

Given how inexpensive the blowers are and how much of a hassle the job can be, you might be better off just getting a new unit.

Good luck.

I was assuming that they weren't available new for whatever the OPs application is.  If they are then I agree that spending the coin for a new one is probably the way to go.

Good point, I didn't consider that.

I attended my local Cars & Coffee this morning and one of my best friends there is notorious for throwing massive amounts of time at a problem in an effort to save a few dollars and I think my prospective was affected by that.
