Blower motor tech, not sexy, but useful
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.

Love to hear about cheap fixes. Nothing beats good old fashioned farm thinking.

Sounds like this access hole could be drilled without removing the blower. Is that true? Could you post a pic of the finished product?
Tips like this are great - thanks for sharing! ![]()

Re: Blower motor tech, not sexy, but useful
Yes, you could definitely drill the hole and lube the motor with it installed.
In my case though, the motor was too seized up to even turn over electrically. I had to remove it to allow me to turn the squirrel cage by hand to free the motor up. I'll get a picture, but it will be Friday till I'm back at work and have internet access tp put it up.

Re: Blower motor tech, not sexy, but useful
Its a good idea to check all the fuses too. I just had one go out and aside from the motor just bein bad in general both my ac and heater fuses were blown.

Re: Blower motor tech, not sexy, but useful
I've done this a few times too... I like graphite powder instead of speay lube, although it wouldn't have helped much with alocked up motor like in this case.

Re: Blower motor tech, not sexy, but useful
I've used this fix for years.It usually works but I have had to replace the motor a couple times even after doing it.I guess they burn up electrically from not running after a while.

Re: Blower motor tech, not sexy, but useful
That's what we used to do before these trucks were classics. We didn't have silicone sealer then, we used a piece of clay to cover the hole. It comes off easy, and can be re-used. One of those things stored in the back of my brain. Now if I could remember them without prompting like this and write them down....

Re: Blower motor tech, not sexy, but useful
Great tip. I had to replace the heater core in my truck and the business with the hood hinge was a pain.

one and pivot the hinge out of the way to remove the motor. In case you do not wish to remove the hinge. Good tip Kevin! ![]()

It really wasn't too bad. I probably spent 15 minutes on the whole job, including cleaning the leaves and crud out of the heater box behind the blower motor.
