Something you may not realise is that the brake light bulb is often one bulb with two elements. One of the elements will be for the brake and the other will be for the tail lighting for example so,when tested, the actual bulb will still light up because the second element is unaffected. Make sure that the 'blown' bulb that you are actually changing is not in fact your fog lamp. This will not automatically light up when you test your lights as you have to operate this light separately (similarly to indicator lights). So the fog lamp bulb will appear to be the only one not lit up when you test your lights. Find the bulb with two elements inside and change that one. Sounds obvious (and may be obvious to many) but it's a common mistake. Hope this helps!.
Adjust or replace the brake light switch.
The same thing happened to me. It's the brake lights switch either under or over the brake pedal. The same thing happened to me. It's the brake lights switch either under or over the brake pedal.
Defective or misaligned brake light switch.
It may be a defective brake light switch. The location of the brake lights fuse is listed in your owner's manual.
The brake light switch is stuck or out of adjustment. If it is a mechanical switch it is located somewhere on the brake pedal swing arm. If it is a pressure switch it is located near the Master Cylinder.
Defective or out of adjustment brake light switch.
if it isn't a fuse or lamp problem, check the brake lamp switch on the brake pedal, if you unplug the switch, and jumper the connection, and you have brake lamps, replace the switch...
Then the brake lights are out but the middle one still lights up. (:
check for blown brake light bulbs and broken wires. also check brake light switch on brake pedal
The brake pedal switch is bad. How do I replace it?
Assuming you have the lights turned off, you are seeing the brake lights. They are more than likely on because the brake light switch is defective or out of adjustment.
check the bulb if not blown wiggle the hazzad switch brakes run through the hazzad switch just try it not positive
