After cleaning out the insides with electrical cleaner and compressed air and slipping it back together I began bench testing and rediscovered the squeal I'd forgot all about. With a little bumping and repositioning it will go away but that won't be an option when it's installed. So it's clear I need to apply a little grease to the bushings but.... whats the best lube for the job? Heater motor pics

Put a little on the shaft under the blade. Drill a small hole in the rear of the case & put a little oil in the rear bushing.

White Lithium is my guess but thought I'd ask someone who doesn't have to guess.

Fan? bearing? etc. Sometimes loosening the assembly bolts just a little will stop it. Any oil will work. Motor oil, sewing machine oil. Don't use spray oil. Drop very small amount while running motor with a 12V battery charger. See if it stops after a few drops at base of shaft(s). The spinning and gravity will carry it down and in, Not too much!!! It will generally stop making noise while running and you are listening in a quiet place. Once you know where it was making noise you can lube that place a little more/better. If it's the fan just bend a few blades that are touching. White lithium is for mechanisms with little or no RPM's. used on hinges, locks, seat tracks, etc.
