    Weird that both will come on at the same time.

    So, let's check one light problem at a time.

    Brake light.

    How is the brake fluid level?



    Charge/battery light.

    When you start the truck, and the charge light is on; leave the truck running. Disconnect the negative terminal to the battery.

    If the truck stalls out, then the alternator is bad.

    If the truck does not stall, then there might be a bad connection to the battery or the battery might be going bad.

The charge and the brake lights are designed to illuminate when the voltage regulator in the alternator fails.

Repce the alternator, and you will be fine.

How do I repair a brake booster motor


You should be able to get a "rebuild kit" for the booster. There are rubber seals and diaphragms in the booster that can go bad.

After replacing air filter, car did not start. After jumping the car, it started, but dash lights and headlights flickered softly. Ran for 45+ min. Afterward, car fails to start again.


The battery is either flat or faulty , charge or replace. not a good idea to jump start with out special leads . this can cause a spike and damage ECU. and alternator .

Battery light and brake light were on, card wont


Nissan truns the brake and battery light on when there is a charging issue. When you say it wont start does that means it craks or no? If it does not crank I would attempt to charge the battery then try to start it and check the charging system.
