1996-2000 Pathfinder & QX4 High Mount Stop Lamp: Solving 'Lights Stuck On' & Spoiler Fitment

Vehicle & Part Compatibility

This lamp assembly is a direct fit for the following vehicles, provided they do not have a rear spoiler:

• 1996-2000 Nissan Pathfinder
• 1997-2000 Infiniti QX4

The original part number 26590-0W000 was used on models produced from late 1995 to March 1996. It was then superseded by part number 26590-0W010 for all subsequent models up to 2000. The parts are interchangeable.

Most Common Symptoms of Failure

Diagnosing a problem with the high mount stop lamp is usually straightforward. Here are the most common failure scenarios, from simple to complex.

1. Lamp Does Not Light Up

This is the most frequent issue. When you press the brake pedal, the two main brake lights work, but the center high mount lamp remains off. The cause is almost always one or more burned-out bulbs. Since the lamp contains five bulbs, it may grow progressively dimmer as each one fails before going out completely. Less common causes include a loose electrical connector or a blown fuse, although the fuse often protects all brake lights, not just the center one.

2. Brake Lights Are Stuck On

If your main brake lights and the high mount stop lamp stay on even when your foot is off the pedal, the problem is almost certainly not the lamp assembly itself. This issue is extremely common on older Nissan vehicles and is caused by the failure of a small, inexpensive plastic stopper on the brake pedal arm. This stopper presses a switch that turns the lights off; when it becomes brittle and disintegrates, the switch remains open, and the lights stay on, draining your battery.

3. Visible Moisture or Water Inside the Lens

Over time, the foam or rubber gasket that seals the lamp assembly against the liftgate can degrade. This allows water from rain or car washes to seep into the housing. This moisture can cause corrosion in the bulb sockets and lead to premature bulb failure. If left unaddressed, it can also lead to water stains on the interior liftgate trim panel or rust on the liftgate itself.

4. Cracked or Faded Lens

Years of exposure to sunlight and weather can make the red plastic lens brittle, hazy, or cracked. A faded lens will reduce the light's brightness, making it less effective as a safety device. A cracked lens will allow water to enter the housing, leading to the electrical issues mentioned above.

Buying a Used High Mtd Stop Lamp: What to Look For

A used OEM lamp is often a great value compared to a new dealer part and can be superior in quality to cheap aftermarket alternatives. However, inspect the part carefully before buying.

• Inspect the Lens: Check for any cracks, even hairline fractures. Minor surface scuffs can be polished out, but cracks compromise the seal. Ensure the red color isn't significantly faded.
• Check the Gasket: Look at the condition of the foam gasket on the back of the lamp. If it's compressed, brittle, or crumbling, it will not seal properly and should be replaced to prevent water leaks.
• Examine the Bulb Sockets: If possible, twist out one of the bulb holders and inspect the metal contacts inside the socket and on the holder itself. Look for any white or green corrosion, which indicates past water damage.
• Verify Mounting Points: Ensure that all plastic mounting tabs and screw holes are intact and not cracked or broken. A lamp with broken tabs will not mount securely to the liftgate.
• Confirm Compatibility: Double-check that you are buying the lamp for a non-spoiler model. The shape is distinctly different from the spoiler-integrated version.

Cost of Replacement

The cost to fix a high mount stop lamp issue can vary dramatically, from less than a dollar for a bulb to several hundred for a new assembly from the dealer.

Replacement Guide (Difficulty: 1/5)

Replacing the bulbs or the entire lamp assembly is a very easy DIY job that requires only a Phillips head screwdriver and about 15-30 minutes.

1. Open the Rear Liftgate: Secure the liftgate in the fully open position.
2. Remove the Trim Panel: On the inside of the liftgate, there is a plastic access panel directly behind the stop lamp. Remove the two Phillips head screws holding it in place.
3. Access the Bulb Holders: With the panel removed, you will see the back of the lamp assembly with five round bulb holders.
4. Replace the Bulbs: To replace a bulb, twist the corresponding holder about a quarter-turn to the left and pull it out. The bulb pulls straight out of the holder. Push the new bulb in, re-insert the holder, and twist it to the right to lock it in place.
5. Replace the Assembly: To replace the whole unit, first disconnect the main electrical connector. Then, locate and remove the nuts that secure the lamp assembly to the liftgate. The lamp can then be removed from the outside of the vehicle.
6. Test and Reassemble: Before reattaching the trim panel, have a helper press the brake pedal to ensure all new bulbs and connections are working. Then, reinstall the access panel and its screws.

Recalls and Technical Service Bulletins (TSBs)

As of this writing, there are no specific recalls or TSBs from Nissan or the NHTSA for the high mount stop lamp on the 1996-1997 Nissan Pathfinder. The most significant recalls for this vehicle generation involve potential strut tower corrosion in cold-weather states.
