1967 Ford Galaxie Headlight Switch Repair Guide

A less typical issue faced with a 1967 Ford Galaxie is a faulty headlight switch leading to intermittent or complete loss of headlight functionality. This guide walks you through the repair process, detailing key diagnostic criteria, potential pitfalls and tips for successful repairs.

Diagnostic Steps

Once the car lights are turned on and off intermittently, the most obvious sign of a faulty headlight switch is the headlights dimming or failing completely.
A less obvious diagnostic sign is hearing a sound similar to plastic cracking or snapping when operating the switch.
The final step in diagnosing a faulty headlight switch is to access the back of the switch and utilize a multimeter to check for continuity. If continuity is lacking or irregular, the headlight switch is likely faulty.

Repair Steps

Disconnect the battery as a safety precaution.

Potential Pitfalls
