does your car have DRL option (canada) daylight running lights?)
my answer will be, non export jeep. USA jeep, no one ever says !!!!
the tail lamps are not brake lamps.
they are independant.
there are many parking lamps , and the tails are that.
do all parking lamps fail>? see FSM page 8w50-2
the tails run directly to the park headlight switch pin, marked park.
which gets power from fuse 34
the same switch and pin runs all other park lamps and same fuse 34.
so if the fuse is good, then all lamps are burned out , nah.
or the switch is bad, and can due to so many lights for so long.
if lamps are not dim then here is no short, so must be an open
Fuse 34 tops list , use an ohmeter to test the fuse. or replace it
as , they can get hair line cracks. inside fues
0 ohms = good, infinity = bad fuse.
Hi, the switch runs on fuse 17 inside the car. If the fuse is good, the likely problem is the brake switch above the pedal. You can verify this by pulling the connectors off the switch and connecting the terminals manually with a large paper clip to turn the lights on. If that works, replace the switch.
WITH A GOOD FUSE TESTER, TEST ALL THE FUSES FUSEBOX UNDER THE HOOD & INSIDE THE VEHICLE. IF THE FUSES ARE ALL GOOD WITH THE TESTER YOU MUST HAVE A BAD BRAKE LIGHT SWITCH OR A BAD TURN SIGNAL SWITCH. THE BRAKE LIGHT CIRCUIT GOES UP THROUGH THE TURN SIGNAL SWITCH & THEN TO THE BRAKE LIGHTS. FIRST OF ALL IS THE BRAKE LIGHT SWITCH GOOD ? THE ORANGE WIRE FEEDS THE BRAKE LIGHT SWITCH, THE WHITE WIRE PUTS POWER TO THE TURN SIGNAL SWITCH, SO THE LIGHTS CAN BE USED AS TURN LIGHTS OR BRAKE LIGHTS. , PUT A TESTER IN THE WHITE WIRE & PRESS ON THE BRAKE PEDAL. IF THE TEST LIGHT LIGHTS UP, BRAKE LIGHT SWITCH IS GOOD, BY THE WAY THE BRAKE LIGHT FUSE MAY BE LABELED" STOP", THE FUSE LABELED" BRAKE" IS FOR THE ABS SYSTEM. TO CHECK THE TURN SIGNAL SWITCH FOR BRAKE LIGHTS, REMOVE THE PLASTIC COVER FROM UNDER THE STEERING WHEEL, PRESS ON THE BRAKE PEDAL, PUT THE TESTER IN THE SMALL YELLOW WIRE, THEN THE SMALL GREEN WIRE. IF THERE IS NO POWER IN EITHER WIRE, THE TURN SIGNAL SWITCH IS BAD.
CHECK BRAKE LIGHTS FUSE IF FUSE GOOD CHECK FOR POWER AT BRAKE SWITCH.IF YES BRAKE SWITCH FAULTY.IF NO POWER TO BRAKE SWITCH YOU HAVE A OPEN WIRE FROM THE BRAKE LIGHT FUSE TO THE BRAKE LIGHT SWITCH.
Look at fuse #18, a 15 amp fuse, in the fuse block. This fuse powers both the tail lights and instrument cluster lights. Usually both of these light systems are powered by the same fuse so when your cluster isn't lit up you'll know right away that your tail lights aren't working as it's not safe to drive without tail lights. Your brake, turn, and head lamps are powered by different circuits. Hope this helps and good luck!
I'm not sure about the location of a particular fuse, but it is good practice to check all of the fuses anyway. Once you have checked all of the fuses that are inside, there is a separate set under the hood. There should be a diagram on the inside of the cover. After checking all fuses, there are relays associated with the brake lights. They are located in the same box under the hood. You can not check it, you will have to replace it. Have you replaced the bulbs? If the problem is your brake lights, it might be the switch that is associated with your brake pedal, which activates the lights. If it is the running lights, then it is most likely a fuse or relay. The running lights are the ones that come on when you turn your headlights on.
it is fuse #23 in the fuse panel inside the passenger compartment, not under the hood. it is dead center in the fuses.
fuse #39 is partially used for the brake lights, but many other things also run through it. good luck
the problen is probably the turn signal switch with a test light check for power at brake switch if no power check for power at turn signal switch the brake lights are incorperated through the turn signal switch
