Hi! The problem will be on the brake light switch located underneath the dash at the brake pedal. It is faulty for sure and stuck on the brake mode thats why the brake lights are always on. You will have to have it replaced. Hope this helps and have a good one!

Engine shuts off when brake is released


That's better with spaces.

The engine is not connected to the brakes. The only electrical item on the brakes is the brake light. The brake light is not connected to the engine. When the brake light turns off, why would it stop the engine?

So in my mind, the two are not connected. For weird things like this, you have to visit a dealer who is an expert with your make and model of car.

What would cause engine yo die at a stop light and not start again. The engine almost turns over but doesnt.


engines stopping at lights can sometimes be attributed to a vacuum leak in the brake booster
test by idling the engine with the hand brake on and no foot brake then apply the foot brake and if the engine dies then it is the brake booster
hard to restart may be the vacuum leak if you still have your foot on the brake.

Red spanner warning light


Brake Light. Make sure you are not driving with hand brake on. Check brake-fluid level. Top off brake fluid if low and make appointment to check brakes. Driving with brake light can be dangerous; deal with this soon. Call tow truck or drive carefully and slowly to shop.
ABS (antilock brake system) Light. Indicates either low brake-fluid level, stuck brake caliper or faulty ABS. Check brake fluid and make appointment to get brakes checked. Call tow truck or drive carefully and slowly to shop.
Oil Light. Either engine is very low on oil or there is no oil pressure. Pull over and turn off engine immediately. Check oil level and add oil if low. Turn engine back on to see if light has gone off. If oil light is still on, bad oil pump (no oil pressure) is likely. Call tow truck.
Check Engine Light. Car's computer senses engine problem. Difference in performance may not be noticeable, but make appointment to have car diagnosed. This usually cost around $65-$75 to do. OK to drive. If problem is serious, computer may switch to limp-home (low-power) mode and you won't have option of waiting to bring car into shop.
Air Bag Light. Get air bags checked. Problem could prevent them from activating in accident. OK to drive, but not safe in accident.
Battery Charge Light. Alternator is not charging. OK to drive, but turn off any unneeded electrical devices (radio, heater, defroster) and avoid starting engine more than necessary. Bring car into shop soon to avoid getting stranded. When alternator is not charging, battery loses charge and car stops working.
Emissions Lights (O2 sensor, EGR, check emissions). Depending on car model, these lights may indicate problem with emissions sensor or may light up at certain mileage, usually 60,000 miles (100,000 km). Get sensors checked. OK to drive. If problem exists, car might get poor gas mileage.

Instrument cluster brake and check engine light stay on


The brake light can stay on if the master cylinder is low on brake fluid or if the emergency brake is on. The switch that turns the brake light on could be stuck on by the emergency brake pedal or handle. The check engine light is on because the cars computer senses a fault in the cars system. Have a mechanic shop scope the cars computer

Rear brake lights won't turn off


Check brake light switch (likely faulty). This issue may not be related to the engine issue.
If not the brake switch then check wiring for possible short circuit.

I have a 2000 Jeep Grand Cherokee. My problem is that when the engine is ON my left brake light WILL NOT light up when the brake is applied... BUT when the engine is OFF, and the brake is applied, the...


the only thing that should separate the right and left brake light is the turn signal switch i think if tis vehicle has seperate light bulbs for the turn signals and brake lights it will not involve the turn signal swicth. either way ther is a voltage loss somewhere. test with a voltmeter at the brake light switch with the engine on and off,if it is vastly deferent go back to the fuze and ceck both sides of that,then back to the ignition switch.you should probably locate a wiring diagram.if the brake light and turn signals are the same bulbs you will need to ceck the turn signal switcth.this is removeable after taking off the plastic cover behind the steering wheel and held on by two scews very small torx head scews.it is referd to as a combination switch.
