The button on your dashboard
Worn brake pads can cause the brake light to blink on the dash in a 1993 GMC Sierra 1500. This can also be caused by a faulty light.
could be a problem with the sesor in the emergency brake. a bad connection there could cause the light to blink with the vibration of the car running On some cars, the brake warning light will blink if the parking brake is set, and you drive... it could be a failed parking brake switch, assuming the brake is not applied. It is supposed to blink to get your attention. One car that does this is the Mitsubishi Starion, there are probably some others, too.
Having too much play in the emergency brake handle in the middle of the console could lead to the brake light flickering. At least this was true for me.
its a ground wire
Defective battery or something is pulling power from the battery. Check the glove box light, interior lights, trunk light, hood light, brake lights, etc.
Yes
Misfire detection.
The flasher unit for the indicators. Pressing and releasing the foot brake for the brake lights. Turning the light switch on and of for the others. If it is not any of these then there is an electrical fault, possibly a loose connection.
ive put in brake fuild oil toped that up checked the battery level all ok still the battery light and hand brake light are still on...
Either the battery has a dead cell and needs replacing, or alternator is defective, loose or corroded battery cables, or something is draining the battery. Look for a courtesy, trunk, under hood, glove box light that is on. Also can be a defective brake light switch which causes the brake lights to stay on.
check the brake fluid level. check all the brake linings for thickness.
brake light and battery light is on
