Headlight Guide: 1998-03 Windstar, 04-07 Freestar & 05 Thunderbird

Headlight Assemblies for Windstar, Freestar, and Thunderbird

1998-2003 Ford Windstar Headlight Assembly

The second-generation Ford Windstar uses a large, one-piece composite headlight assembly. These are known for becoming hazy or yellowed with age, which significantly reduces light output and can be a safety hazard.

Bulb Type and Technology

The Windstar uses a single 9007 (HB5) dual-filament halogen bulb for both the low and high beams. This bulb has two filaments inside: one that illuminates for low beams and another, brighter one for high beams. The assembly is designed exclusively for halogen bulbs and does not have factory HID or LED options. It does not require any external ballasts or driver modules.

Known Issues, TSBs, and Recalls

• Lighting Control Module (LCM) Failure: A critical issue for Windstar owners is Ford Recall 15S39 (NHTSA 15V861). This recall addresses a faulty relay inside the Lighting Control Module, which can cause the headlights to fail intermittently or completely while driving. Symptoms include headlights turning off unexpectedly. This is not a failure of the headlight assembly itself, but of the module that powers it. Ford dealers can install a bypass kit to remedy the issue.
• Hazy / Yellowed Lenses: Like most polycarbonate lenses from this era, the Windstar's headlights are prone to UV damage, causing the clear outer lens to become foggy and yellow. This severely restricts light output.
• Melted Connector: Some owners have reported the electrical connector for the 9007 bulb showing signs of melting or heat damage, which can indicate a poor connection or failing bulb.

Replacement Information

Replacing the entire assembly on a Windstar requires basic tools. The assembly is typically held in by several screws or bolts accessible from under the hood. The most challenging part of the job is often on the driver's side of 1999-2003 models, where the battery's location makes accessing the back of the headlight difficult. Many DIY mechanics find it necessary to remove the battery to gain enough clearance to change the bulb or disconnect the assembly.

2004-2007 Ford Freestar Headlight Assembly

The Ford Freestar, which replaced the Windstar, features a completely different headlight design and a much simpler replacement procedure. Like its predecessor, its primary weak point is lens hazing over time.

Bulb Type and Technology

The Freestar uses a single H13 (9008) dual-filament halogen bulb for both low and high beams. This is a different bulb type than the Windstar and they are not interchangeable. The assembly is a standard halogen setup with no ballasts or external modules.

Replacement Information

Ford significantly improved the serviceability of the headlights on the Freestar. The entire assembly is held in place by two long retaining clips or rods at the top. To remove the assembly, simply lift these two clips straight up, and the entire housing can be pulled forward and out of the vehicle. This tool-free design makes bulb changes or assembly replacement exceptionally easy and fast.

2005 Ford Thunderbird Headlight Assembly

The retro-styled 2002-2005 Thunderbird has distinctive round headlights set into a larger assembly. A key issue for owners is the availability of original parts.

Bulb Type and Technology

Despite its premium market position, the Thunderbird uses a standard 9007 (HB5) dual-filament halogen bulb, the same type used in the Windstar. There were no factory-equipped HID/Xenon options. The system is a simple halogen design without ballasts.

Known Issues

• Discontinued OEM Parts: According to specialist retailers, original Ford OEM headlight assemblies for the 2002-2005 Thunderbird are out of production and no longer available from Ford. This makes used OEM and new aftermarket assemblies the only viable replacement options.
• Difficult Retaining Clips: While the replacement process is tool-free like the Freestar's, some owners report that the retaining clips holding the assembly can be very stiff and difficult to pull up. Applying a spray lubricant to the clips can make removal much easier.

Replacement Information

Similar to the Freestar, the Thunderbird headlight assembly is held in by two retaining clips that are pulled upward to release the housing. Once the clips are removed, the assembly can be pulled forward to access the wiring and bulbs.

Symptoms of a Failing Headlight Assembly

• Dim or Yellow Light: This is most often caused by an aging halogen bulb or a hazed, oxidized outer lens that blocks light.
• Moisture or Condensation Inside: Water droplets or fog inside the lens indicate a failed seal. This can short out bulbs and corrode the reflective surfaces, permanently damaging the assembly.
• Flickering or Intermittent Operation: While this can be a sign of a failing bulb, it could also point to a loose connection, a corroded socket, or a more serious electrical issue like the Windstar's LCM problem.
• Cracks or Physical Damage: Damage from road debris or minor impacts can break the lens or mounting tabs, compromising the seal and the assembly's structural integrity.

Buying a Used Headlight Assembly: What to Look For

A used OEM headlight is often a better choice than a cheap new aftermarket part due to superior materials, fit, and reflector quality. Here’s what to inspect:

1. Check the Part Number: Double-check that the part number matches your vehicle's specific year and model. As shown in this guide, parts from a Windstar will not fit a Freestar.
2. Lens Clarity: Look for a clear, un-hazed lens. Minor hazing can sometimes be polished out, but heavy yellowing or internal cloudiness cannot be fixed.
3. Mounting Tabs: Carefully inspect all plastic mounting tabs and clip points. These are often brittle and can be broken during removal from the donor vehicle. A single broken tab can cause the headlight to vibrate or be misaligned.
4. Seals and Housing Integrity: Check the housing for any cracks, especially around the seams where the lens is bonded to the back case. Ensure the rubber seals for the bulb access ports are present and pliable.
5. Reflector Condition: The chrome reflector inside should be bright and shiny. Any flaking, discoloration, or burnt spots will severely degrade performance.
6. Connectors: Look at the electrical connector pins to ensure they are clean and free of corrosion.

Cost Comparison

Prices can vary based on condition and supplier. These are typical estimates.
