Compare: Used OEM vs. New Aftermarket

• Used OEM: Offers the best value. These are genuine factory parts that have been tested and inspected. They are typically much cheaper than new parts.
• New Aftermarket: These are brand new parts made by third-party manufacturers. They are built to meet or exceed OE specifications.

Used OEM:

• These are original equipment parts that came from the factory.
• They are tested to ensure they are working properly.
• They offer a cost-effective way to repair your vehicle.

New Aftermarket:

• These are brand new parts made by companies other than the original manufacturer.
• They are often more affordable than new OEM parts.
• Ensure the aftermarket part is from a reputable manufacturer.

• USB Ports: If the wireless charging isn't working, the USB ports in the same area might also be affected.
• Center Console Wiring Harness: Damaged wiring can cause issues with the wireless charging system.
• Fuses: Blown fuses are a common cause of electrical problems.

Why Replace Related Parts:

• Replacing related parts can prevent repeat failures. If the original problem was caused by a voltage spike or other electrical issue, other components may have been damaged as well. Replacing these components at the same time can help ensure that the problem is fixed correctly and doesn't recur.

• The Wireless Charging Control Module typically lasts 5-10 years.

Factors That Affect Longevity:

• Operating Temperature: Extreme heat can shorten the lifespan of the module.
