Tools you'll likely need:
* Phillips head screwdriver (likely a small one)
* New turn signal bulb (match the wattage and type – check your owner's manual or the old bulb)
* Possibly a small pry tool (plastic is best to avoid scratching)
Steps:
1. Open the rear tailgate or door: Access the taillight assembly you need to work on.
2. Remove the taillight assembly: This is usually done by removing screws or by carefully prying the assembly away from the body of the vehicle. Look for screws on the inside edge of the taillight housing. There might be several clips holding the assembly in place. Gently pry these apart starting at the top or bottom, working your way around. Don't force it; use a plastic pry tool to avoid damage.
3. Locate the turn signal bulb: Once the taillight assembly is removed, you should be able to see several bulbs. The turn signal bulb is usually one of the larger ones and may be amber colored. Your owner's manual or a diagram on the back of the taillight assembly might help in identifying it.
4. Remove the old bulb: The bulb is generally held in place by a socket or a retaining clip. Gently twist the bulb counterclockwise to remove it. If it's a bayonet style, carefully push and twist.
5. Install the new bulb: Insert the new bulb, making sure it's seated correctly and making contact with the socket. Turn it clockwise to secure it.
6. Reassemble the taillight assembly: Carefully put the taillight assembly back into place, aligning it correctly and securing all clips or screws.
7. Test the new bulb: Turn on your hazard lights or turn signals to verify the new bulb is working correctly.
Important Considerations:
* Disconnect the battery's negative terminal: This is a good safety precaution to prevent accidental short circuits.
* Be gentle: Avoid excessive force when disassembling and reassembling the taillight assembly.
* Bulb type: Ensure the replacement bulb is the correct type and wattage for your Tahoe. Incorrect wattage bulbs can lead to premature failure or damage to the wiring. The bulb will likely have a number code stamped on its base (e.g., 3157, 1157, etc.).
If you encounter any difficulties or are uncomfortable performing this repair yourself, it's best to take your vehicle to a qualified mechanic. They have the experience and tools to safely and effectively replace the bulb.
