The most likely cause is a bad brake light switch (if none of the brake lights illuminate) but if its only one of the brake lights, try changing the bulb. Even if they still work as running or turn lights because they have a double filament and may still work partially, but not as brake lights.


A blown bulb. Check fuses and then start replacing the bulbs one by one.



Are you sure it is your running lights & not just the brake lights? A bad brake light switch (common problem) will cause your brake lights to stay on all the time because they are not wired to the accessory switch, meaning they will work whether the truck is on or off. Hope this helps!


The BOO (Brake On/Off) Switch may need to be replaced. If it is bad, it would cause the brake lights to NOT illuminate when the brake pedal is applied.


have you tried turning the ouside dial on headlight switch that dims the gages bright or dull had a similar problem with 98 corvette no dash lights or hvac or running lights turned out to be multi function switch (headlights turnsignals)




The most probable cause is that the brake light switch is out of adjustment.


Nonfunctional Brake LightsOne possible cause of this issue is that the brake light switch is not adjusted properly, or the switch could be defective.


More than likely it is the brake light switch that is attached to the brake pedal.



every vehicle must have brake lights to indicate that the vehicle is stopping. with no brake lights the vehicle can cause a rear end collision.



This is usually cause by a stuck brake light switch on the brake pedal. Replace it.


You probably need to replace your brake light switch. It's near the top of the brake assembly, beyond a trim panel. The fact that all three brake lights don't work rules out problems in the multifunction switch (the cause of similar problems affecting only the two rear lights.)


Could be a bad wiring harness, disruption of the circuit somewhere between the brake pedal and the brake lights, a bad switch which fails to actuate the brake lights. See sources and related links below for bulb information.


bad switch on brake pedal? do you have brake lights?


The most common cause for brake lights to be out on a 2001 Mustang GT is a blown bulb. There are some instances where there is faulty wiring.


A loose or corroded ground wire will cause the fuse to blow. Check the ground wires on your brake lights.


I found this on my 1997 Silverado and found the connection from the wiring harness to the back OS the switch itself was loose, I could wigle it arouns and make the lights come back on.


the daytime running lites go out when you put the trans in park. they also go out when you depress the parking brake. i would start looking there.


there is a number of things that could cause this. here are a few easy ones to check. is the e-brake fully disengaged. are the bulbs burnt out. is the wiring harness plugged into the daytime lights bulbs and in good condition. if these check out, you may have a fault in the daytime running light module.


check the brake light switch behind the brake pedal under the dash.
