The 1999 Lincoln Town Car, like many vehicles, utilizes fuses to protect its electrical circuits from overloads. Understanding the fuse box locations and diagrams is crucial for diagnosing and resolving electrical issues. This model actually incorporates two distinct fuse boxes: the passenger compartment fuse panel and the power distribution box located in the engine compartment. Knowing the function of each fuse can save you time and money when troubleshooting electrical problems, including issues that might affect your OBD2 diagnostic port.

Notably, Fuse #23, a 20A MINI fuse, is designated for the “Datalink Connector” and the interior cigar lighter. The Datalink Connector is better known as the OBD2 port, which is essential for vehicle diagnostics. If you are experiencing issues connecting your OBD2 scanner to your 1999 Lincoln Town Car, checking this fuse should be one of your first steps. A blown fuse here will prevent communication with the car’s computer system, hindering any diagnostic efforts.

While this power distribution box may not directly house a fuse labeled “OBD2”, it contains fuses crucial for the Powertrain Control Module (PCM), such as Fuse #4 (30A MAXI – PCM Power Relay). Issues with PCM power can indirectly affect OBD2 functionality, as the PCM is the main computer that the OBD2 port communicates with. Therefore, if you’re facing broader diagnostic communication problems, it’s wise to check fuses in both the passenger compartment and the power distribution box.
By understanding these fuse box diagrams and the function of each fuse, you can effectively troubleshoot electrical problems in your 1999 Lincoln Town Car, including issues related to your OBD2 port and diagnostic capabilities. Always refer to your vehicle’s owner’s manual for the most accurate and up-to-date information.
