How to replace the headlight assembly or headlight bulb, as well as the cornering, sidemarker, park, or turn signal bulb on Cadillac CTS?

Before working on the headlamp or signal bulbs you must raise and support the vehicle. Open the hood after removing push-pin retainers from the air deflector to reach the fascia extension retainers. To start adjustment remove a single push-pin retainer from the center to enable flexing of the grille. Rephrase this task first by removing the bolt between the front fascia and fender, followed by unplugging the bolt that fastens the front fascia to the fender. Place the fascia studs into the enlarged slot in the key slot from the fender side before slowly pulling down to separate it. Unbolt the three headlamp holders from the vehicle while disconnecting the headlamp washer pipe (if present) and pulling the lamp toward you to unlatch it from the fender socket. Separate the headlamp electrical connector while moving the front assembly towards the top to take out the headlamps from their position. Unscrew and separate both the lamp cover and bulb from your headlamp unit ensuring halogen bulb safety guidelines. Begin by installing the bulb to the headlamp and adding the headlamp bulb cover later. Pivot the top front fascia and grille to expose the headlamp assembly and remount it to the vehicle. Use both hands to press the headlamp assembly backward after connecting all electrical inserts located at its rear end until it snaps into position with the fender. Connect the headlamp using 3 bolts and tighten them to 6 N.m (53 lb in). Move the top fascia forward then downward to insert the fascia studs into fender keys and move the fascia back into place. Attach the bolts (1, 2) to secure the fascia and tighten them to 9 N.m (80 lb in). Reposition the front fascia extension then push-retainers to secure the grille and upper fascia part into the tie bar. Finally lower the hood and car. Put the air deflector in its proper position and secure it using push-pin retainers when done lowering the car.
