Replace a fog light bulb or assembly on a 2003–2005 Saturn Ion by disconnecting the lamp, preserving its adjuster position, and testing the beam after installation.
Tools you will need

Parts and supplies

Steps
- Replace the bulb if needed
Rotate the bulb socket counterclockwise and unplug its harness. Handle the replacement bulb by its base, connect it to the harness, and twist the socket back into the lamp if changing only the bulb.
- Remove the fog light assembly
Remove the 10mm retaining bolt and pull the lamp forward from the bumper. Note the adjuster screw position before removing the old assembly.
- Install the replacement fog lamp
Set the new lamp's adjuster near the original position and guide the assembly into its mount. Reinstall the 10mm bolt, reconnect the bulb socket, and ensure the wiring is not pinched.
- Test and aim the lamp
Switch on the fog lights to confirm the bulb illuminates. Adjust the beam as needed using the lamp adjuster and verify the assembly is secure.
