If the electrical relays malfunction internally, they can cause the hazard lights to act up. The emergency lights are wired through the turn signal and flasher relays. These are usually located in the fuse panel found in the engine bay, in some cases one relay controls both functions.
There are several reasons why the hazards might turn on when you open the door. Typically when you open the door the jamb switch which controls the connection to your radio and interior lights is triggered to turn on and off. This switch is the first place you should look.
The lights flashing when locking the car usually indicate that all doors have been locked. But when it fails to flash, that could mean that your car`s sensors are malfunctioning, one of your doors is still open, or there are problems with the hood`s latch.
Check the switch to the hazard lights and see if the switch got stuck. Sometimes the switch tends to stick and make the hazard lights stay on. If the switch is working, then the contacts in the switch have burned and fused together. Remove the fuse and remove the switch and replace it.
Flashing emergency vehicle lights are most commonly seen on police cars, ambulances, and fire engines. These vehicles, when they are moving in response to an emergency situation, have to be allowed to move faster than the other automobiles on the road.
the 3 flashes means alert, warning, or danger.
Yes! Hazard lights can drain the battery of your car. Any electrical device in your vehicle can become a drain if its left on such as headlights, radios, and even door pins. These things can be problematic if they are left operating when your vehicle`s motor is off.
Hazard lights indicate that a vehicle is stopped, broken down, or needs assistance. When hazard lights are on, it affects the way the turn signal and brake lights work. Therefore, it makes it difficult for drivers around you to tell if you are stopping or turning.
If your turn signals have stopped working, it`ll be doing one of these things: blinking rapidly, coming on without blinking, or nothing at all. The good news is that all of these symptoms point to two possible issues, a bad turn signal relay or a dead bulb.

One of the most common causes of headlight flickering is a dying battery. Your headlights rely on power from the battery to function properly. If the battery is failing, flickering, or dimming headlights may be the result.
Seeing occasional flashing lights in your eyes usually isn`t an issue. But repeated flashes in the forms of bright spots, streaks of lightening, or shooting stars in the corner of your eye can indicate a serious medical condition.

Security light constantly on or flashing, battery light flashes, radio locked, power locks and dome lights don’t work. Please help
ANSWER : Hi there, thanks for writing in. I’d be happy to provide my insight.
I would not replace the BCM without a thorough diagnosis first. GM vehicles such as yours suffer from two small wires that break in the steering column. They attach to the ignition lock cylinder that is part of the security system. But this doesn’t cause all the other power problems and the car will crank every time. If the security system is acting up, you can turn the ignition in the run position for ten minutes. If the car starts after ten minutes, then you most likely have a security issue.
The first thing I would do is to connect a scanner and see if I could communicate with all the computer modules. This will be a good indicator of whether or not the BCM is failing. In addition, any codes that are stored could be retrieved and these are very often excellent guides as to what is the problem.
If I were working on your car, I would look at all the connections that supply power to the fuses. This will require a repair manual or access to a professional level automotive information system. Following this, I would study a wiring diagram to see if there is a common connection that supplies power to all of the systems that are not working.
When it comes to computer modules, they are rare to fail. For this reason, I rule out every other possibility first before I suspect and then begin to directly test the suspected module. I recommend the following inspection to help you diagnose your car: Electrical problems are not working inspection.
Hope this helps, and best of luck.
Good luck!
In my 2006 Porsche Cayenne Turbo (955), after the car is turned off and locked the hazard lights flash on the front and the back for about 40 seconds
ANSWER : Hello. This is a problem within the vehicles control module. The main body control module that controls the lighting either has an internal hardware failure or an issue with the programming. I usually try reprogramming the system first and if that does not solve it then the module needs to be replaced. The dealer is the best place to take this vehicle for this type of repair.
My car stalls at times, yesterday the car shut off at a red light. I turned car off then back on now engine light is on.
ANSWER : This may be a result of a dirty or failing idle air control valve. The idle air control valve reads the air intake as it is mixed with fuel prior to being injected into the engine at low speeds and at idle. Since this valve is controlled by the vehicle’s computer, it will adjust idle speed based upon other measurements such as engine temperature, intake air temperature and electrical system load or voltage. When you accelerate, the engine RPM increases, and as you let off the gas, the RPM slowly returns to the normal idling speed with the help of the idle air control valve making the transition from a higher RPM back down to idle speed. When the engine RPM drops below the normal range of about ~800 RPM, this often times will cause the engine to stall indicating a dirty or faulty idle air control valve. I would recommend having an expert from YourMechanic come to your location to diagnose and replace your idle air control valve.
Replaced alternator on car 2 times each time shows it’s charging 14v let car run for a little bit then test drive and car voltage
ANSWER : There are reports that the replacement alternators will not communicate with the engine computer and will not charge correctly. I recommend using only the manufacturer approved replacement part. It can be new or remanufactured but approved for use in the vehicle. Some lower cost alternators on the aftermarket will have charging problems since they will not communicate with the ECM on the vehicle and will stop charging.
Driving, then engine/oil light turns on, steering locks up, car dies; but just fine after turning off than on.
ANSWER : Any time loss of steering, or power assist to the steering is lost, it can be a safety issue and should be looked into as soon as possible. If the oil light and/or check engine light are flashing before it stalls, it can be a few different issues causing this. Also, a fault code may be stored in the system. Warning lights flashing after the engine stalls is normal. Most engine control units monitor readings from the oil pressure switch as well as the dozens of other sensors. Make sure the engine oil level is correct. If the oil pressure switch is intermittently losing it’s signal, then the ecu may think there is no engine oil pressure and shut down as a safety measure.
Have a certified technician look into the engine stalling as soon as possible. Losing steering and brake assist can be a safety hazard.
Check engine light and oil light comes on before oil change?
ANSWER : Hi There,
As you may know, these lights are designed to come on at specific mileage intervals that are preset by the factory. When your mileage exceeds a certain amount relative to the last oil change, this will trigger the lights to come on. Typically this will include the oil light and the check engine light as there are also other basic service items that are checked during oil changes. I would recommend obtaining an owner’s manual for your car if you do not already have one. This will usually indicate the specific service intervals and recommended maintenance items for your vehicle at the various mileage intervals.
The tire pressure monitor will also come on when the air pressure in the tires has reached a specific threshold relative to the tire design specification. Tire pressure is also impacted by the outside air temperature. For every 10° drop in air temperature outside your tires will lose about 1% in PSI or inflation. As you may know, as the temperature of the air changes the density of the air changes as well causing the tire pressure to be impacted by this. When this happens, the sensors in the wheels will detect this change in tire pressure and cause the tire pressure light to come on. Aside from replacing faulty tire pressure sensors, another way to help prevent this type of fluctuation in tire pressure is by the use of Nitrogen in your tires rather than regular air. As you may know, air is approximately 78% Nitrogen, 21% Oxygen and the rest is water vapor and some other small concentrations of gases. Nitrogen is much less likely to migrate through tire rubber than oxygen. This will maintain your tire pressure much more consistently during large temperature fluctuations.
Battery and oil light come on when trying to start car, take keys out try again car starts no problem and lights go away
ANSWER : Of course, don’t switch gears without being fully stopped, unless your Owner’s Manual or the manufacturer has alternative advice. However, the gear shift issue has no relation to the no-start problem you are describing. Inasmuch as you only have 6,000 miles on the car, the "constant on and off" that you believe has occurred is meaningless in comparison to the expected total vehicle service life. That is, assume what you perceive as "constant on and off", during merely 6,000 miles, might be equivalent to using the car "normally" for three years. A new car should be trouble free for at least 5 years, unless there is a defect, so your "constant on and off" is not a causal factor for any fault on the vehicle. What you might have is a defect in the ignition switch, or perhaps the immobilizer system, but if the problem is not in the switch itself, clearly there is an electrical problem.
If your vehicle is under warranty, by law the dealer MUST repair the issue you are describing within a prescribed time frame and number of "attempts", otherwise the dealer will run afoul of Federal and state Lemon Laws that give you very specific rights, and recourse (contact an Attorney; we are Mechanics, NOT attorneys). Consequently, if the vehicle is still under warranty, to save yourself money do be sure to seek a resolution from the dealer. If the vehicle is not under warranty, obviously a certified Mechanic from YourMechanic could identify the electrical fault and resolve this for you. If you want to go that route, please simply request a no start diagnostic -electrical system and the responding certified mechanic will get this taken care of for you. If you have further questions or concerns, do not hesitate to re-contact YourMechanic as we are always here to help you.
