How do you Change, Replace, or Install Broken 2003-2007 Cadillac CTS Fog Light / Signal Light Assembly Replacement

Fits years: 2003, 2004, 2005, 2006, 2007

All Cadillac CTS Fog Lights for sale Tools required:
  • Flathead screwdriver

  • 10mm socket/ratchet with extension

  • 7mm socket/ratchet

  • Needle-nose pliers

Step 1: Open the vehicle's hood.

Step 2: Remove 8 retaining pins across the top of the headlight radiator area, 8 across the bottom of the bumper cover, and 3 in each wheel well.

To remove these pins, simply use the flathead screwdriver to pull the center of the pin up, and then pull the entire pin from the vehicle.

Step 3: Pull the wheel well protective panel away from the bumper cover to expose two 10mm retaining bolts. Remove these bolts from each side.

You will need to remove market light completely in order to reach the second bolt on each side!

Step 4: Gently remove the front bumper cover from the vehicle. Be sure to disconnect the wiring harnesses from each side's light assembly!

Step 5: The fog light assembly is attached to the bumper cover, so accessing it now is easy! Loosen and remove the 7mm retaining bolts (one is one the front and the other two are on the back).

Step 6: You can now pull the fog light assembly from the vehicle.

NOTE: If you ordered your replacement fog light from Go-Parts, it likely includes a new bulb/socket, as many of our models do! However, in case it doesn't, turning the socket counter-clockwise will allow you to pull it from the assembly for attachment to the new one.

Step 7: Mount your new fog light assembly to the bumper cover by tightening the three 7mm retaining bolts.

Step 8: Reconnect the wiring harnesses of each side's lighting area, and reattach the front bumper cover.

Step 9: Reattach the side marker light.

Step 10: Tighten the 10mm bumper cover retaining bolts in each wheel well and be sure that all of the retaining pins are solidly in place!
