I have a 2004 Sorento EX and my EXT fuse along with the stop lamp fuse kept blowing. The ext would blow as soon as I turned the vehicle on. The stop lamp would blow after a couple pushes of the brake pedal causeing me to have no rear lights at all regarding brake and the lights that you turn on at night. After much reading online in forums such as this, I was led on a chase looking for grounding wires, broken wires, dirty battery terminals, faulty altinator, and for a drl module. I could not find a drl module as I now do not believe there is one in sorentos, or at least in mine. I then came to the brake switch that is located on the arm of the brake pedal. I disconnected it, put a couple of new fuses in, started my vehicle and checked my fuses, and at last they did not blow! I reconnected the brake switch and checked the fuses and they had blown. I have a hunch that I am dealing with a faulty brake switch. Hope this helps
If you keep blowing the brake fuse than you have a short in the system. Unplug the brake switch. Install a new fuse. If it did not blow than the problem is after the brake switch. Next unplug the turn signal switch, then plug the stop light switch back in and press the brake pedal. Did the fuse blow. If not than the wiring is good in between the two switches. With the turn signal switch disconnected use a jumper wire in between the light green wire (power from the brake switch) and the orange with light blue wire (power to the right brake lamp). If the fuse blows than there is a short in the right side brake circuit between the plug in and the rear socket assembly. If the fuse does not blow than jump from the light green wire to the Light green with orange wire (power to the left brake lamp). If the fuse blows than the problem is in the left hand brake wiring circuit.
check wiring on shift columb going to turn signal switch it could be the switch it self I had this happen on a new chevy truck hope this helps good luck jerry
The power flow for the brake lights goes like this: Fuse ->Brake switch -> Turn signal switch -> Rear lights. The only difference is, if you have a 3rd brake light in your rear window, that gets its power directly from the brake switch. It does not go thru the signal switch first. So, if you are having a brake light problem, and your fuses are good, check the 3rd light in the rear window, if it lights up (assuming the bulbs are good, no one ever changes them), then the problem is most likely in the turn signal switch, hope this helps!
You most deffinatly have a dead short, thank god for fuses. You will need to chase all realated wires , look for a bare spot in a wire thats touching something metal. Good luck
First let's determine which brake lights are not working. Does the high mounted brake light work? Do both left and right brake light not work? If none of the brake light work, the problem could be the brake light switch at the brake pedal OR fuse #12 in the underhood fuse panel. If only the bake lights at the corner lamp assembly don't work, check fuse #34 in the rear fuse panel. The module your are referring to is the circuit board located in each of the corner lamp assemblies, check on website www.compnine.com for the part number of this item. I don't believe this is your problem though.
there is a short circuit in the brake light wiring it could be in the lamp holders them selfs pull off the wires to the brake lights holders on all the lamps and see if it still blows a fuse if it dose then the short is in the loom not the lights them self's if it dont blow a fuse hook up one light at a time untill it starts to blow fuses again the last light to be hooked up that blows the fuse is the faulty light
