During the day, no brake lights. At night, all lights function properly. Brake lights do not work. Fuse is a 10A but when I replace the fuse, as soon as I apply the brake, it blows out.
----- Three questions-----
Why use the vehicle-resolve the problem
Do not replace any fuse that blows,even once
Get a wiring diagram & trouble shoot the circuit
that blew the fuse
If that has worked for me for 50 years
I think that will help you & point you in the
right direction
Sounds good Peter but I'm not electrical savy and wouldn't know how to read a wiring diagram much less follow one properly. The lights worked perfectly since I bought the jeep and I have not added any aftermarket equipment since purchase so I cannot think of what the problem could be. I won't put another fuse in per your suggestion
All you have to do I guess is what you have done for years Give your money to a repair shop & hope for the best Keep in mind we choose what questions to answer or pass on & have to decide what the person wants & 99% of the time have no vehicle knowledge so feelings get hurt Soory

Hi .. First I would remove the lamps, and try the brakes, then try again with the wiring harness disconnected from the housing, to see if you can isolate the problem to the lamps, the housing, or the wiring. If it is the wiring , then you will have to trace the harness back toward the front of the car looking for any place where the insulation on the wire has been damaged .
The Tail lights and Instrument lights are usually on the same circuit so both will go out if the fuse for the circuit blows. Check for a blown fuse for this circuit and replace if out. If fuse continues to fail, check the tail light or side globes for a faulty globe and replace if necessary. Also check for any chafed wires that could be shorting to the body causing the fuse to blow.
