1999 Lincoln Town Car OBD2 Fuse: Location, Troubleshooting, and FAQs

The 1999 Lincoln Town Car, like most modern vehicles, relies on the OBD2 system for engine diagnostics. A crucial component of this system is the OBD2 fuse, which protects the circuitry from electrical overloads. Knowing the location of your OBD2 fuse and how to troubleshoot common issues can save you time and money.

Locating the OBD2 Fuse on a 1999 Lincoln Town Car

The OBD2 fuse on a 1999 Lincoln Town Car is typically located in the power distribution box, often referred to as the fuse box. There are two fuse boxes in this vehicle: one under the hood and another under the dashboard on the driver’s side. The OBD2 fuse is most likely in the under-dash fuse box.

To find the fuse box under the dashboard:

1. Open the driver’s side door and locate the fuse panel cover on the side of the dashboard.
2. Consult your owner’s manual for the fuse box diagram, which will indicate the exact location of the OBD2 fuse. The fuse is usually labeled “DLC” or “OBD II“.

Troubleshooting a Blown OBD2 Fuse

If you suspect your OBD2 fuse is blown, these steps can help you troubleshoot the issue:

1. Identify the Symptoms:

• Your OBD2 scanner won’t connect to the vehicle’s computer.
• Other electrical components, like the cigarette lighter or radio, might also malfunction if they share the same fuse.

2. Inspect the Fuse:

• Carefully remove the OBD2 fuse from the fuse box using a fuse puller or pliers.
• Examine the fuse wire. A blown fuse will have a visible break or gap in the wire.

3. Replace the Fuse:

• If the fuse is blown, replace it with a new fuse of the same amperage. The fuse box diagram or your owner’s manual will specify the correct amperage.

4. Address Underlying Issues:

• Don’t ignore a blown fuse! A blown fuse is often a symptom of a larger electrical problem. If the new fuse blows immediately or shortly after replacement, you likely have a short circuit or another electrical fault that needs to be addressed by a qualified mechanic.

“Ignoring a blown OBD2 fuse can lead to more serious electrical damage,” cautions John Miller, a veteran automotive electrician. “It’s vital to diagnose and repair the root cause of the blown fuse to prevent recurring issues.”

Common FAQs about 1999 Lincoln Town Car OBD2 Fuse

Q: What is the purpose of an OBD2 fuse?

A: The OBD2 fuse protects the circuitry of your car’s onboard diagnostic system. It acts as a safety device, breaking the circuit if there’s an electrical overload that could damage sensitive electronic components.

Q: Can I drive my car with a blown OBD2 fuse?

A: While you can technically drive your car with a blown OBD2 fuse, it is not recommended. You won’t be able to use your OBD2 scanner for diagnostics, and the underlying electrical issue could worsen, leading to more serious problems.

Q: What are some common reasons for a blown OBD2 fuse?

A: A blown OBD2 fuse can result from a short circuit in the OBD2 port, a faulty OBD2 scanner, or a problem with the wiring harness. Other potential causes include using an incorrect amperage fuse or improper installation of aftermarket accessories.
