Update
I recently posted this on a new thread, but forgot that I had this one going. Here's the resolvement of the issue:
So, I decided to check the heater blower on my car (1982 300D) even thought the previous owner said that the brushes had been replaced in the last couple of years.
Well, when I took out the old brushes, they were just tiny stubs with copper wire stuck to them.
....but wait, there's more!
As I was inspecting the unit, turning it around, two more pieces of brush fell out on each side (3 total on each side). Someone had taken the stuby remains of other brushes and packed them in with the stuby brush with the copper wire attached in the back of each "pack." I could tell that they weren't each just one that broke into three pieces because each piece had the grooved and curved end, indicating contact with the center post of the motor.
I'm going to give the previous owner, because he's probably taking his daughter's 124 to the same mechanic who did this "repair."
No wonder the darn thing kept on sputtering out.
Runs like a hurricane now (as long as my "expert" soldering decides to hold out).
Pete.
