Q: How do you remove the Headlight Switch in a Oldsmobile Cutlass?
A: To remove the lighting switch in a 1974-1977 model, start by disconnecting the negative cable at the battery. Then, remove the steering column cover from the bottom of the dashboard for better access. With the Headlights in the 'full on' position, reach up under the dashboard and depress the lighting switch shaft retainer while pulling gently on the lighting knob. Remove the shaft and knob assembly. Next, remove the nut securing the lighting switch to the carrier. For better access, remove the screws securing the instrument cluster carrier and tilt the cluster. Unplug the electrical connector at the switch and remove the switch. To install, reverse the removal steps, ensuring all ground connections are refastened and the switch shaft is fully seated in the switch, with the shaft retainer locking it into place. For the 1978-1980 model, disconnect the negative battery cable and remove the cluster pad assembly. Then, remove the retaining screws and pull away the switch.
