When buying an Airbag Control Module, look for:

• A module that is specifically made for your car's year, make, and model.
• A module that has been tested and inspected to ensure it works properly.
• A seller with a good reputation and a warranty on the part.

Quality indicators to look for:

• For used OEM modules, look for ones that are clean and free of damage.
• Ask if the module has been tested to meet original factory specifications.

Typically, you'll get just the Airbag Control Module itself. You may need to reuse your existing mounting hardware.

Difficulty level: Moderate. Estimated time: 1-2 hours.

Special tools needed:

• Socket set
• Screwdrivers
• Scan tool to clear airbag codes after installation

Critical steps and tips:

1. Disconnect the car battery before starting any work on the airbag system. This is very important for safety!
2. Locate the Airbag Control Module (usually under the center console or under the seats).
3. Disconnect the wiring harness from the old module.
4. Remove the old module and install the new one.
5. Reconnect the wiring harness.
6. Reconnect the car battery.
7. Use a scan tool to clear any airbag codes.

DIY is possible if you're comfortable working on cars and have the right tools. However, because airbags are a crucial safety system, professional installation is recommended if you are not experienced.

You have two main choices when buying an Airbag Control Module: Used OEM and New Aftermarket.

Used OEM: These are genuine factory parts that came from the original manufacturer. They offer excellent value because they are tested, inspected, and available at a lower price than new parts.

New Aftermarket: These are brand new parts made by third-party companies. They are built to meet or exceed the original equipment specifications.

Both options can be good choices, depending on your budget and needs.

Parts that are often replaced or checked at the same time:

• Clock spring (located in the steering wheel)
• Airbag sensors
• Seat belt pre-tensioners

Replacing related parts can prevent repeat failures because a problem with one part can sometimes damage other parts in the system. For example, a faulty clock spring can cause the airbag warning light to come on, even if the Airbag Control Module is working properly.

An Airbag Control Module can last for the life of the car. However, its lifespan can be affected by:

• Accidents
• Water damage
• Electrical problems
• Extreme temperatures

Used OEM: $50 - $150 New Aftermarket: $100 - $300

Labor costs for installation can range from $100 to $300, depending on the shop and the complexity of the job.

Total job cost:

• Used OEM: $150 - $450
• New Aftermarket: $200 - $600

For 2002-2004 Buick, Chevrolet, GMC, Isuzu, and Oldsmobile vehicles, a common issue is water damage to the Airbag Control Module due to leaks in the windshield or sunroof. Check for any signs of water damage before installing a new module. Some owners have reported issues with the module after replacing other airbag system components, so it's important to diagnose the problem correctly before replacing the module.

After installing the new Airbag Control Module:

1. Start the car and check if the airbag warning light turns off after a few seconds.
2. Use a scan tool to check for any new error codes.
3. If the airbag warning light stays on or you get new error codes, there may be another problem with the airbag system.
4. Listen for any unusual noises from the airbag system.
