Where can I find the light control module in a 2004 Volvo VNL truck?

The 2004 Volvo VNL, a commercial vehicle made by Volvo, could have issues with its external lights. Some drivers have reported that their headlights stay on even after removing the key from the ignition. This problem is related to the truck's light control module (LCM), which is situated in the middle of the dashboard under the VNL's fuses. While owners can swap out the LCM themselves, they will need a Volvo dealership to program it. The module can be customized to support LED lights, fog lamps, and alerts for light failures. Headlight problems may also be caused by wiring that isn't properly grounded. To address this, check under the hood, including the battery, to ensure the wiring connections are correctly grounded. Replacing the LCM in a Volvo truck typically costs between $250 and $300 just for the parts.
