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

Get a new brush and switch assembly

Get a whole new motor

Or do I have any other options?

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.

What parts store are you buying brushes from? I did not know you could buy them separately but I will definitely try that first. The brush came completely off.

If I'm making new brushes I buy acdelco alternator brushes and cut them down
With a dremel, then finish them up using small files and sandpaper to get the right fit
