Those lights are on different circuits. The high and low beam lights are powered thru the headlight switch, the turn signals, brake, and hazards go thru the turn signal switch. I would want to know if each circuit has power at the switch that controls it.
Well usually when the third brake light works and the others don't, the problem is in the turn signal switch. The center brake light is separate from the other two as far as circuits go. The thing that puzzles me is the cruise. It could be something else, because the only way a faulty brake light switch would kill the cruise control is if the switch was stuck on. I think I would check the circuits in and out of the turn signal switch.
need to check the multi-function switch. the brake light signal goes through the turn signal switch on the steering column. the brake lights come on if the turn signal is not being operated. the circuit for the brake light can loose contact in the switch.
As for the brake lights push brake pedal down while pushing on and wiggling the hazard switch.If the brake lights come on then replace the multi-function switch.
Have had this problem many time's here at my shop, if center brake light come's on which you said it does, fuse and relay are good, the problem is your turn signal switch cause the brake light circuit goes through the switch, the switch is bad even though the turn signal's still work's, good luck, hope this was evrey helpful.
brake lights won't work, but the center does ??? u need to change your turn signal switch which is in the steering wheel. i changed mine and it worked great .....
Hello. The symptoms you are describing are likely due to a poor ground. Temporarily install a new ground wire by securing a piece of copper wire to the frame with a self tapping screw. Use this ground wire along with the hot wire to see if each of these lights works. If it does, trace the ground wire back to the frame, unscrew it and clean up the metal with emery cloth so you reestablish a good ground.
It sounds like a wiring fault - an earthing problem. Have a look around the lights/inside the lights themselves.. rear and front lights, brake lights, etc ...check the wires for corrosion/splitting. In particular check any black earth leads where they attach to an earthing point.
The problem is the turn signal/headlight/hazard switch assembly on the steering column which the brake light wiring runs through. The part is easy to change and cost about $50 at most parts stores
