A/C Blower Motor brushes replaced - now noisy

I replaced the brushes in my climate control blower motor recently with the kit from ************** and now it squeals. The loud squealing comes and goes and is caused by the bushings in motor.

My question is, what should you lube the motor bushings with? I used a R/C car motor bearing oil when i replaced the brushes. This seems to have attracted tiny contaminents and causes noise when motor is spinning.

Should it be a dry lube?

Smile Answer

Any standard SAE 30 or 10W 30 through 50 works.
On rare occasions I have used 90W gear oil to extend the life of very bad bushings (personal cars only).

Remove the squirrel cages to fully access your bushings, it takes time for the thicker oil to penetrate as you are lubing the bushings, (roughly five to seven minutes of exercise to work in).



Have a great day

OK, have heard ATF works best and does not soften the insulation on the commutator

I work on small equipment all the time, and a few years ago I started using 2 cycle synthetic chain saw lube for all the smaller bushings and bearings. It seems to not dry out as fast, and also doesn't make as much black deposit on the bushing. Works for me!
