How to Replace a Headlight Bulb on a Cadillac CTS

Model: Cadillac Cts MK 3 - Years 2014-2019
Part: Headlight bulb

If you need to replace the headlight bulb on this vehicle, you can find general instructions below and also use the tutorial video for assistance. The first step is to open the hood and remove the clips securing the upper part of the front grille and the bumper. Next, remove the clips securing the wheel well. Above the front grille, there are screws that need to be removed to detach and take off the bumper. This will give you access to the screws securing the headlight assembly, which you will need to unscrew. At this point, you can pull the headlight out towards yourself and proceed to replace the burnt bulb by removing the rear cover of the housing and then disconnecting the power connector. Replace the bulb, reconnect the connector, and then reverse the steps to reassemble all components.
