1991 Pontiac Firebird Parts Questions & Experts Answers

• Q: How do electrically operated concealed headlights function and what are the manual opening methods in emergencies on 1991 Pontiac Firebird?

  A: The electrically operated concealed headlights utilize a permanent magnet/actuator motor connector linked to an assembly that raises and lowers the headlights. When activated from the dashboard switch, relays control the motors, which turn off upon reaching the full open position and are reactivated to close the assemblies when the switch is turned off. In emergencies, manual opening methods vary based on the headlight door motor model. For motors with a single-hole knob, a ballpoint pen or similar object can be inserted into the hole and turned clockwise until a click is heard, allowing for manual closure by reversing the action, ensuring no voltage is present at the motor terminals by disconnecting the electrical connections at the isolation relay on the right side of the vehicle's radiator cradle. For motors with a knurled knob featuring two holes, the headlights should be turned on, and the hood opened; turning the knob clockwise until the assembly is fully open will require increased effort and may produce a click when the limit is reached. To close the assembly manually, the headlights must be turned off, and the knob should be rotated counter-clockwise.
