How do you replace a Front Turn SIgnal Lamp on 2005 Buick Terraza?
Place vehicle in safe parked position.
Crawl under front bumper.
Reach up and turn lamp housing counter clockwise.
Housing should drop down to about the bottom of the bumper.
Re - Insert Bulb Housing in Lamp and Turn Clockwise to secure.
To change the signal light on a Buick Terazza remove the headlight above the turn signal. Open the hood, there is one bolt/screw on the the top-outside edge of headlight and a 4--5 " L shaped fastner on the other side. Turn the L fastner and pull up and out. Now work the headlight out around the seals. The turn signal is directly below. Turn the light socket counter clockwise to remove bulb.
