Replacing the tail light on your 2019 Toyota Highlander XLE can be a straightforward task if you follow these detailed steps. First, ensure you have the correct replacement tail light for your vehicle. You can purchase the part from a Toyota dealership or an authorized auto parts store. Additionally, gather the necessary tools, which typically include a Phillips head screwdriver, a flathead screwdriver, and a small pry tool.

Step 1: Safety First - Before you begin, park your Highlander on a flat surface and turn off the engine. Engage the parking brake and remove the key from the ignition.

If you have a helper, ask them to assist you by holding a flashlight or keeping an eye on the vehicle's stability.

Step 2: Access the Tail Light Assembly - Open the trunk of your 2019 Toyota Highlander XLE. Locate the tail light assembly on the side you need to replace. You will see a plastic cover on the inside of the trunk that needs to be removed to access the tail light. Use a flathead screwdriver to gently pry off the cover.

Tools You Need to Replace the Tail Light on Your 2019 Toyota Highlander XLE

Replacing the tail light on your 2019 Toyota Highlander XLE is a straightforward task, but having the right tools on hand can make the process much smoother. The primary tools you will need include a Phillips head screwdriver and a flathead screwdriver. These screwdrivers will help you remove the screws that secure the tail light assembly to the vehicle. Additionally, a plastic pry tool or a trim removal tool can be useful for gently prying out the tail light without damaging the surrounding plastic.

For safety and precision, consider using work gloves to protect your hands and a flashlight to illuminate the work area, especially if you are working in low light conditions. A socket set or wrench set might also come in handy if you need to remove any additional bolts or brackets. Having a multimeter can be beneficial to test the electrical connections and ensure that the new tail light is functioning correctly before you fully install it.

Lastly, having a new tail light assembly and any necessary wiring harnesses or bulbs is crucial.

Common Issues with 2019 Toyota Highlander XLE Tail Lights and How to Fix Them

One of the most common issues with the 2019 Toyota Highlander XLE tail lights is burned-out bulbs. Over time, the bulbs can wear out and stop functioning, leading to dim or completely non-functional tail lights. To fix this, you will need to replace the faulty bulbs. First, ensure the vehicle is turned off and the key is removed. Open the trunk and locate the access panel for the tail light assembly. Remove the panel and gently pull out the bulb socket. Insert a new, compatible bulb and reassemble the components. It's crucial to use the correct type of bulb to avoid further issues.

Water infiltration is another frequent problem that can cause the tail lights to malfunction. Moisture can enter the tail light assembly, leading to fogging, corrosion, and short circuits. To address this issue, start by checking the seals around the tail light assembly. If the seals are damaged or worn, replace them to prevent water from entering. Additionally, you can apply a silicone sealant around the edges of the assembly to create a watertight seal. If the problem persists, you may need to disassemble the tail light and clean any corroded parts before reassembling.

Electrical issues can also affect the functionality of the 2019 Toyota Highlander XLE tail lights. Loose or corroded wiring connections can lead to intermittent or complete failure of the lights. To diagnose and fix electrical problems, begin by inspecting the wiring harness and connectors for any signs of damage or corrosion. Use a multimeter to test the continuity of the wiring and ensure that power is reaching the tail light assembly. If you find any faulty connections, repair or replace them as needed. In some cases, you may need to consult a professional mechanic to ensure the wiring is correctly installed and functioning.

Lastly, cracked or damaged lenses can impact the performance and appearance of the tail lights. Cracks or chips can allow moisture to enter the assembly and can also affect the light's visibility. To fix a cracked lens, you can either repair it using a specialized kit or replace the entire lens. If you choose to repair the lens, clean the area thoroughly and apply a clear resin or epoxy to seal the crack. For a more permanent solution, replacing the lens is recommended. Ensure you purchase a high-quality, OEM-replacement lens to maintain the original look and functionality of your 2019 Toyota Highlander XLE.
