[TR] TR4A - Heater Motor

[G.D. Huggins]

All,

So there I was, head in hand wondering aloud, “How is this effing thing still so slow’?

While doing the prep work to replace a bad wiper wheel assembly, I decided to address my non-functioning heater, you know, since I was under the dash and all.
After getting the heater on the bench, I discovered the problem was one of the very small bolts that hold the motor into the top sheet of the heater body had come free, and the motor was tilted, mechanically binding.  So, I pulled the motor, wired directly to the car’s battery and it spun fine!

However, it produced about as much wind as an old lady blowing on my knees.
So today, I tore it down, cleaned it up, polished the surfaces, and re-insulated the internal wires.
Put it all back together, hooked it to the battery at it spins.. THE SAME LOW SPEED!!
So all that reconditioning had zero effect.

Desperate for advice, I am wondering if hooking it directly to the car battery might be too much power?
I mean, I would expect that raw energy to make the damned thing take flight or something, with zero resistance in the line.

Any sage advice?



Cheers,
