Blower motor tech, not sexy, but useful

[Tx Firefighter]

I was fixing the heater on my beater this weekend and finally pinpointed it as a bad blower motor.

I removed the motor, which is a pain, as the hood hinge had to come off.

After removing it, I noticed it was stiff to turn.

I put it face down on the bench and drilled an 1/8 hole in the very tip of the housing. This exposed the very tip of the motor shaft and allowed me to lubricate the bushing. Then, I squirted light oil down into the housing using a syringe. After a few minutes of turning the motor by hand, it had noticeably loosened.

After reinstalling the motor, it worked. I put it on low speed and sprayed a few more drops of oil down into the housing as it was running. After a minute or two, the motor was working and sounding just like brand new.

Finish up with a tiny dab of silicone to keep dirt out of your new lube hole.

That's 40 bucks saved, to be put towards more sexy trucks parts.
