Check the headlight switch first:
https://www.fierostore.com/.../Detail.aspx?s=514262nd Generation Headlight Motors:
If your headlights fail to rise and the motors keep spinning, check/replace the bushings/dowels/pins in the motor gear.
Both
Rodney Dickman and
The Fiero Store sell kits.
If the motors do not run, it is more likely is the Headlight Control Module.
If you need a Headlight Control Module, I can dig a thread with an aftermarket source which is cheaper than GM's Module which it is
still available but double the cost or more....
