You can remove the panel inside the back of the car. From there you can access your tail lights and your tag lights.
you need to remove the bumper cover to access the horn. The horns at below to the out side of the head lights
you haft to remove the bumper first to get to the bolts holding in the lights
Yes you just need to change the headlights and bumper lights along with the bumper
first remove the bumper turn lights...two screws on one each light..then remove the lights carefully, so you do not break them.... After that...remove the bumper screws in the wheel wells.... Then, where you have removed the bumper lights...with a socket extension..and a 12 mm socket...remove two bolts on each bumper mounts.....then the bumper should come off in a forward direction.... you now have access to both headlight assemblys.
On my 98 Tahoe under the bumper behind the are where the tag is located you just pull the light assembly out. It has a little pressure clip. replace light and replace assembly the same way.
There are 3 screws located under the front bumper under the light you need to replace take these 3 screws out and you have full access to all the lights in front. do this for each side.
if it is the same as a 2001 one then just unscrew the light cover(there should be two screws on the cover) and you should be able to access the bulb. If the wiring falls inside the bumper just put your hand under the bumper and push it back out. CAUTION: turn off your lights when changing the bulbs as it will be hot if left on.
their are 4 plastic nuts in the trunk that loosen the light assembly that the lights are in. Remove those and pull the assembly out and twist the connector for the license plate light to access the bulb.
To change the side marker lights on this model, remove the screws of under cover that attaches to the bumper. It would be easiest to do if the vehicle was lifted up in some way.
The tail lamps are serviced from underneath the vehicle, between the frame extension and rear bumper.
The rear fog lights are accessable from under the car. You have to reach up and under the rear bumper.
