Need to change a turn signal & back brake

Most car like yours require tail lamp removal to acces the bulbs, inside the trunk there will probably be some type of carpet light trim directly behind the lamp. You will either be able to fold it out of the way or there may be some type of clips that hold it. once the trim carpet has been moved you will have either plastic "wing" nuts or regular nuts to remove to pull the lamp away from the body (or you may have direct access to the bulb sockets) once the lamp is away from the body & the sockets are exposed, it is a squeeze and turn to remove the socket from the lamp. be sure to get the correct bulb - besure to re-assemble correctly or water leak may occur. the procedure may be outlined in your owners manual

PLEASE DON'T FORGET TO RATE!!!

Rear Turn Signal, Brake, & Marker Lights

1. Disconnect the negative battery cable.
   
2. Open the trunk.
   
3. Unfasten the nuts or other retainers from the rear trim.
   
4. Unfasten or release the housing cover retainers.
   
5. On some vehicles, you may have to remove the rear fascia/body panel and light assembly to get to the sockets.
   

1. Remove the bulb from the socket using the appropriate method. Bulbs with blade-type bases pull straight out, while those with round bases and protruding pins (bayonet-type bulbs) must be depressed, then rotated counterclockwise (approximaneed to change a turn signal & back brake - 4b5c3aa.gifrn) before pulling out.
   

1. Secure the bulb in the socket using the appropriate method. Bulbs with blade-type bases push straight in, while those with round bases and protruding pins (bayonet-type bulbs) must be inserted, then depressed and rotated clockwise (approximately 1/8 turn).
   
2. Install the lamp socket using the appropriate method. Depending on the type of socket, either engage the plastic tabs, and rotate the socket clockwise (approximately 1/4 turn), or push on the socket until the metal tangs engage.
   
3. Install the housing cover nuts.
   
4. If removed, install the rear fascia and light assembly.
   
5. Install the rear trim.
   
6. Connect the negative battery cable, then check the operation of the rear lights.
