During tail/turn signal lamp replacement always place the headlamp switch in the off position while lowering the endgate or opening the cargo doors. Additionally you should be aware that z-71 tahoes have a rear tail lamp cover which might break while removing it. Detach the body from the tail/turn signal lamp assembly by unscrewing pair of retaining screws before removing the electrical connector. Identify the bulb needing replacement: each bulb has a specific function on the lamp assembly: the top bulb operates as a parking lamp and the central bulb performs back up and indicator functions while the bottom bulb functions as a back up lamp. To replace a bulb simply pull it directly from its base through the built-in tab slots. Begin the installation by inserting the bulb straight into the lamp assembly before tightening the base to the lens assembly with 2 screws alongside reconnecting electrical connectors according to fastener notice in service precautions. Secure the tail/turn signal lamp assembly back onto the vehicle using 2 screws while tightening them to 2 n.m (18 lb in).

To replace the tail/turn signal lamp, first make sure the headlamp switch is in off position and reduce the end gate. Separate the 2 screws on which the tail/turn signal lamp assembly is fixed to the body and locate the bulb that has to be replaced: the top bulb lighting is a parking lamp and stop lamp, the middle bulb lighting is a turn indicator lamp, the lower one is a back up lamp. Turn the socket assembly to take it out of the housing. For the process of installation, torque the socket and tighten in position before reinstalling the tail/turn signal lamp to the vehicle using 2 screws. Lastly, close the end gate and check out the operation.

If you want to replace the tail/turn signal lamp, make sure to get the headlamp switch in off position and the endgate lowered.
