I have 2000 Jeep Wrangler with No Brake lights. Replaced Fuse and both brake light bulbs. Still no brake lights. Tail lights Blinkers and Back up lights work. Any Ideas Thank you very much.?

Answer 1

Although there could be other causes, I suspect that the problem is related to the brake light electrical circuit since you replaced the lamps and fuse [assuming they were all good]. The most common cause of symptoms that you describe suggest that the brake light switch may be involved, either not adjusted properly, or defective. Though not familiar with your vehicle, MOST brake light switches are mounted on or near the steering column, and above the brake pedal arm, in contact with and depressing the switch's plunger [thus holding the switch OPEN], and when the pedal is depressed, allows the switch plunger to extend, closing the switch, allowing electrical current to the circuit and thus the brake lights. This type of switch is genrally mounted by screwing a threaded nipple on the switch into a threaded hole in a mounting bracket. This switch is adjusted by screwing the switch further out or in. A small percentage of vehicles use a hydraulic type switch mounted into a hole on the brake master cylinder on the firewall in the engine compartment. To my knowledge, these switches are not adjustable. Good luck.
