98 Toyota 4Runner- Can a faulty towing cable/wires

although I have not experienced this problem in the exact vehicle you have, General Motors has had problems with the turn signal switches in many of their vehicles. The turn signals may still work properly, but the electric signal from the brake light switch passes through the turn signal switch (also called a combination switch) before it goes to the brake lights. I assume you have no problem shifting out of park or you would have mentioned it, which tells me the brake light switch is functioning properly. First thing to do, as always is to check for blown fuses. If it is a blown fuse, you then need to determine what caused the fuse to blow. If you have towed a trailer recently, it could have been faulty wiring in the trailer, or it could be faulty wiring in the trailer lighting harness of the Escalade.

COULD HAVE FAULTY BRAKE LIGHT SWITCH OR BAD GROUND WIRE AT BRAKE LIGHTS AND TURN SIGNAL LIGHTS.

did you replace the wheel bearings, that is themost common problem for the toy!

if your vehicle lights are working all the fuses will be good. follow the cable from the towing socket on your vehicle , it will most likely go behind one of the rear lights to connect into your cars system,
check your tester where the cables join and you should find the problem. hope this helps.

the cables that go to the rear wheels,one or both are damaged try spraying them with some king of lubricant solvent CRC, WD40, SEAFOAM works best. this should help to release cable, the replace cable, DO NOT DISSCONNECT EMERGECY BRAKE!!!!will not pass inspection

all lights must be working in order for the lights to work in some cars...it's possible that you may have a bad ground wire to the light socket or the you may not be getting power to that socket, which means you have a bad wire. Check to see if you're getting power to that socket with an electrical tester first.

I recommend that you tighten the ground wire screw for starters. since the vehicle is ten years old corrosion may be the culprit.

The trailer harness that was installed probably has a short inside the box that distributes power to the trailer pig-tail. Remove the trailer harness. You problem will be cured.

You have a blown brake lamp fuse.
Start the vehicle, depress the brake, and have someone observe to see if you have brake lights. No brake lights = no removal from park W/O pushing the over-ride switch.
FYI: Brake lamp fuse failures are most always created by a faulty trailer wire harness.

i have a 2003 toyota 4-runner my brake and abs vsc are on and it has a beeping loud noise.....what do u think is the problem?
