Headlights
Headlights is an overview of the pop-up headlight systems used in the Pontiac Fiero.
All Fieros use retractable headlight doors, but there are two main factory headlight systems. The 1984-1986 cars use the first-generation system, while the 1987-1988 cars use the second-generation system.
Overview
The Fiero headlight system includes the headlight switch, motors, linkages, headlight doors, lamps, wiring, relays or control module, and related fuses.
Headlight problems are common because of age, worn motor parts, bad relays, failing control modules, damaged wiring, poor grounds, or mechanical binding in the headlight door mechanism.

Diagnosis
Diagnosis depends on whether the car has the first-generation or second-generation headlight system.
Before replacing parts, check the model year, motor type, fuses, wiring, grounds, relays or module, mechanical binding, and whether the problem affects one headlight or both headlights.
