So one of my headlights (85 so old style) was having trouble going up and down so I cleaned out the gears, resoldered some frayed wire and cleaned the commutators and brushes, but one of the brushes just fell off in this process. Should I
The easiest option is to secure another limiter switch set from a used motor. It doesn't matter which side the limiter switch comes from.
I've been working for over a year to find a way to attach brushes, and The Fiero Store has been working at reproducing the limiter switch it for over 2 years. Attaching brushes is the big holdup.
A suggestion to help avoid brushes coming off: When reinstalling the limiter switch, rotate the motor shaft so that the brushes aren't catching in the grooves of the armature. You can also use a set of snap ring pliers to open up the spring metal brush mounts so that they don't scrub against the armature as you install them.
