2021 - 2024 Chevrolet Trailblazer Fog Light - Right (Passenger) (OEM)

Here's what to look for when buying a replacement fog light:

• Lens condition: Make sure the lens is clear and free of cracks or damage.
• Housing condition: Check the housing for any cracks or damage.
• Connector: Ensure the connector is in good condition and matches the connector on your vehicle.
• Bulb included: Some fog lights come with a bulb, while others don't. Check to see if a bulb is included and if it's the correct type for your vehicle.

Quality indicators to consider:

• OEM vs. Aftermarket: OEM parts are made by the original manufacturer and are generally considered to be higher quality.
• Brand reputation: Choose a reputable brand known for producing quality auto parts.
• Warranty: A warranty can protect you against defects in materials or workmanship.

What's typically included with the part:

• The fog light assembly (lens and housing).
• Sometimes a bulb is included, but not always.

Replacing a fog light is generally a medium-difficulty job. Estimated time: 30 minutes to 1 hour per side.

Special tools you might need:

• Screwdrivers (Phillips and flathead)
• Socket set
• Pliers
• Trim removal tool (optional)

Critical steps and tips:

1. Disconnect the battery: This is a safety precaution to prevent electrical shock.
2. Remove the old fog light: This usually involves removing screws or clips that hold the fog light in place.
3. Disconnect the wiring: Disconnect the wiring harness from the old fog light.
4. Install the new fog light: Connect the wiring harness to the new fog light and secure it in place.
5. Test the fog light: Turn on the fog lights to make sure they're working properly.
6. Reinstall any removed panels: Put back any panels or trim pieces that you removed to access the fog light.

DIY or professional installation?

• Replacing a fog light is something many people can do themselves. However, if you're not comfortable working on your car, it's best to have a professional install it.

You have a few options when buying a replacement fog light:

• Used OEM
• Refurbished OEM
• New Aftermarket

Used OEM: These are genuine factory parts that have been removed from vehicles. They offer the best value because they're tested and inspected to ensure they're in good working condition, but cost less than new parts.

Refurbished OEM: These are factory parts that have been professionally restored to like-new condition. They may have new components installed to ensure optimal performance.

New Aftermarket: These are brand new parts made by third-party manufacturers. They're built to meet or exceed OE specifications.

When replacing a fog light, it's a good idea to check these related parts:

• Fog light bulb: If the bulb is burned out, replace it.
• Fog light wiring harness: Check the wiring for any damage or corrosion.
• Fog light switch: Make sure the fog light switch is working properly.
• Headlights: Ensure your headlights are also functioning correctly.

Replacing related parts can prevent repeat failures. For example, a corroded wiring harness can cause the fog light bulb to burn out prematurely.

A fog light typically lasts for 3-5 years, or around 50,000 to 75,000 miles.

Factors that affect longevity:

• Usage: Frequent use will shorten the lifespan of the bulb.
• Environmental conditions: Exposure to moisture, salt, and extreme temperatures can damage the fog light.
• Quality of the bulb: Higher-quality bulbs tend to last longer.

Here's a general idea of price ranges for fog lights:

• Budget: $30 - $60
• Mid-Range: $60 - $100
• Premium: $100 - $200+

Labor cost considerations:

• If you choose to have a professional install the fog light, labor costs can range from $50 to $150, depending on the shop and the complexity of the job.

Total job cost estimates:

• DIY: $30 - $200 (depending on the part chosen)
• Professional Installation: $80 - $350 (part + labor)

Some 2020-2025 Buick, Chevrolet, and GMC vehicles have been known to experience issues with moisture getting inside the fog light housing. This can cause the bulb to burn out prematurely or damage the wiring. Check the seal around the fog light lens and replace it if necessary. Also, ensure the drain hole (if equipped) is clear of debris.

After installing the new fog light, follow these steps to make sure it's working properly:

1. Turn on the fog lights: Check to see if the fog light turns on and shines brightly.
2. Check the alignment: Make sure the fog light is properly aligned.
3. Inspect the lens: Look for any gaps or leaks around the lens.
4. Test the switch: Make sure the fog light switch is working smoothly.

If the fog light isn't working correctly, double-check the wiring connections and the fuse. If you're still having problems, consult a professional mechanic.

Q: How do I know if my fog light bulb is burned out?
A: The fog light won't turn on, or it will be very dim. You can also visually inspect the bulb to see if the filament is broken.

Q: Can I replace just the fog light bulb, or do I have to replace the entire assembly?
A: You can usually replace just the bulb, unless the housing is damaged.

Q: Are aftermarket fog lights as good as OEM fog lights?
A: Some aftermarket fog lights are very good quality and meet or exceed OE specifications. However, it's important to choose a reputable brand.

Q: How do I adjust the aim of my fog lights?
A: Most fog lights have adjustment screws that allow you to aim the light beam up or down. Consult your vehicle's owner's manual for specific instructions.

Q: Will this fog light fit both the left and right sides of my vehicle?
A: No, this fog light is specifically designed for the right (passenger) side of your vehicle.
