1999-04 WJ Jeep Grand Cherokee Brake Light Bulb Fix

This is a Revit Auto Quick Fix for a 99-04 Jeep Grand Cherokee inoperable brake light. It applies to many other Mopar vehicles.

Parts Needed:

  • New brake light bulb-#3157

Tools Needed:

  • Flat Head Screwdriver
  • Phillips Head Screwdriver


Using your Phillips head screwdriver remove the two screws on the inside of the taillight assembly. Gently move the light assembly away from the vehicle and locate the brake light. It is the top light bulb. Twist the bulb housing and remove. With the bulb removed inspect the three contact locations on the bulb and the plastic piece that holds the bulb to the lamp assembly. Clean and lightly bend the tabs up to ensure that proper contact occurs. Once you have verified your brake light is functioning reverse the procedure.

Helpful tip:

Make sure the lamp assembly's 1/4 panel mount is in place before you install the two screws.
