1. Check the Bulb:
* Access the Bulb: This usually involves removing the taillight assembly. Consult your owner's manual for specific instructions on how to do this for your model year. It generally involves removing screws or clips.
* Inspect the Bulb: Once you have access, carefully remove the brake light bulb and inspect it for damage (broken filament). Even if it *looks* okay, it could be intermittently failing.
* Replace the Bulb: If the bulb is damaged, replace it with a bulb of the correct wattage and type (specified in your owner's manual or on the old bulb). Make sure to insert the new bulb correctly.
2. Check the Fuse:
* Locate the Fuse Box: Your owner's manual will show you where the fuse box is located (usually under the hood or inside the vehicle).
* Identify the Brake Light Fuse: The manual will also show you which fuse is for the brake lights. It may be labeled "Brake," "Stop," or something similar.
* Inspect the Fuse: Remove the fuse and check it for a blown filament (a broken wire inside). A blown fuse will look broken or darkened.
* Replace the Fuse (if necessary): If the fuse is blown, replace it with a fuse of the *same amperage*. Using a higher amperage fuse can be dangerous. If the new fuse blows immediately, there's a more serious short circuit problem.
3. Check the Wiring:
* Inspect Wiring Connectors: Check the wiring connectors at the taillight assembly for corrosion, loose connections, or broken wires. Clean any corrosion with a wire brush and reconnect them securely.
* Trace the Wiring: This is more advanced and requires some electrical knowledge. If you suspect a wiring problem, carefully trace the brake light wiring from the taillight to the brake light switch (located near the brake pedal). Look for any obvious damage or breaks in the wiring.
* Check the Brake Light Switch: The brake light switch is a small switch that activates when you press the brake pedal. If it's faulty, it won't complete the circuit to turn on the brake lights. You can usually test it with a multimeter (measuring continuity) or by visually inspecting it for damage. Replacing the brake light switch is often relatively straightforward.
4. Check the Brake Light Switch (More detail):
* Location: The brake light switch is typically located near the brake pedal, often under the dash or accessible from under the hood. Your owner's manual will have the exact location.
* Testing: With the ignition ON and the brake pedal *not* depressed, check for continuity between the switch terminals using a multimeter. There should be *no* continuity. When you depress the brake pedal, there *should* be continuity. If not, the switch needs replacing.
5. Grounding Issues:
A poor ground connection can also cause brake light problems. Check the grounding points for the taillight assembly – ensuring they're clean and making good contact.
Important Notes:
* Safety First: Disconnect the negative battery terminal before working on any electrical components.
* Owner's Manual: Consult your owner's manual for specific diagrams and instructions for your vehicle.
* Professional Help: If you're not comfortable working on your vehicle's electrical system, it's best to take it to a qualified mechanic. A persistent problem could indicate a more serious electrical fault.
By following these steps, you should be able to identify and fix the problem with your 1995 Jeep Cherokee Laredo's brake light. Remember to replace any faulty parts with the correct replacements.
