How to Replace Headlights on a Cadillac CTSby Matt Scheer
Cadillac CTS headlights are stacked--that is, the high beams are on top of the low beams. This tall profile gives the CTS a sleek, unique look. Fortunately, the design also allows for rather simple removal and replacement of the headlight. The main difficulty in replacing the headlights of a Cadillac CTS is removing all the bolts and clips that keep the grille, bumper, and the headlight housing in place. As long as none of the bolts are stuck or rusted, the replacement process should take you no more than an hour.
Turn off your Cadillac CTS and look below the front grille for the bottom pins that hold it in place. Push these pins inward to disengage them.
Open the hood. Look for the pins that hold the grille in place on the engine compartment side. Push in these pins. Pull the grille off the front of the Cadillac CTS.
Remove the side pins from the CTS fender on the side that has the headlight you wish to replace. Pull the side fender away from the vehicle to prepare for removing the headlight.
Remove the three bolts on the top and rear of the headlight.
Disconnect the wiring harness from the back of the headlight.
Push or pull the headlight through the front of the Cadillac CTS and set it aside. This part may require a lot of force if the headlight is stuck.
Insert the new headlight along the runners upon which the previous headlight sat, and attach the wiring harness. Reinstall the three bolts you removed earlier, as well as the side finder and the grille.
