heater blower motor

[Cruiserhead05]

My blower motor wasnt working. just totally died. i ordered and installed a new resistor lik ei was told to do. This still hasnt fixed the problem. any ideas?

Fuse? Maybe a dirty connection - I find that 30 years of dirt on my rig makes things die. also - connection or short on actual switch at dash fan

Sometimes the switches fail to make a good connection after many years. Have you cycled the switch on and off to see if it works at any point?

Could be that the brushes are shot. Don't know if they are still available, but you can probably make a set or have one made. I haven't modified a set of brushes for a heater motor specifically, but I have for other motors.

Good Luck.

I'd look at brushes if the motor has failed completely and the fuse and switch is good (on high speed the resistors do not have any effect). If you are going to do the brushes make sure that the armature is not severely worn where the brushes ride on. When the motor on my '60 went the brushes were bad but the copper wire that is imbedded in the brush had worn out the armature (the brush length was less that 1/8")

try to put power direct to the motor and see if it works, if yes then check what other said, if no.......I dunno, new motor or used unit

I just recently (last 2 weeks) replaced my blower motor, take the cap of the end of the motor and take a look at the brushes. One of mine had completely worn off and the other was just hanging around. The armature was shot so I had to order another. First check to see if you are getting power to the blower.
