Are the brake lights operational? Are you having any battery recharging issues? If not, I'd be looking at circuit issues such as an open/loose ground or relay malfunction. Good Luck! Dub
could be a bad alternator or battery
The brake light switch is located above the brake pedal on a 1993 Nissan Sentra. To reach the switch the driver's door needs to be opened.
this happened with my 94 sentra just before the alternator died... i would take it to a parts store and have them test the battery and alternator.
brake light on dash blinking
the brake light driver side not working
The 1998 Nissan brake light switch is located below the dashboard, on the drivers side of the engine compartment. The brake light switch simply plugs in and out.
brake light and battery light is on
check your bulbs
Your alternator is defective. Could be the internal voltage regulator or one or more bad diodes. Replace as soon as you can to avoid getting stranded on the road.
To reset the check engine light first lift and prop up the hood of the 2002 Nissan Sentra. Then proceed to remove the negative battery cable for five seconds.
Check the fluid level in the master cylinder.
