Is there a fuse for the 3rd brake light on 97 Jeep Wrangler and what number is it?

The 1997 Jeep Wrangler doesn't have a dedicated fuse *solely* for the third brake light. The third brake light is part of the larger tail light circuit. Therefore, you'll need to check the fuses related to the tail lights.

To find the correct fuse(s):

1. Consult your owner's manual: This is the best resource. It will show you the fuse box diagrams and indicate which fuse(s) control the tail lights.

2. Locate the fuse box(es): The 1997 Wrangler likely has one or more fuse boxes, potentially one under the hood and one inside the vehicle (often under the dash).

3. Check the fuses: Carefully examine the fuses associated with the tail lights (usually labeled as such). Look for a blown fuse (a broken filament inside the glass).

Important Note: If you find a blown fuse, replace it with a fuse of the same amperage. Replacing it with a higher amperage fuse is a fire hazard. If the fuse blows again immediately after replacement, there's a short circuit in the wiring that needs to be addressed by a qualified mechanic. Don't simply keep replacing the fuse.
