Experienced mechanics share their insights in answering this question :
Hello,
This may suggest you have an internal wiring problem, a short or possibly a faulty flasher relay that may be causing your hazard lights to come on intermittently. The flasher is an electrical component that allows the lights to flash on and off as they are designed to when needed. As electrical current is applied to the relay, it causes it to power on and off producing the clicking noise you hear when it is flashing on and off. When this fails, it may cause it to flash rapidly, slowly or in some cases, not at all. I would recommend having a professional from YourMechanic come to your location to diagnose and replace your flasher.

Master warning light – a warning light with a triangle and exclamation point as well as a buzzing sound. This indicates that a malfunction with the system has been detected.
The key Lexus warning lights are either Red or Amber, typically requiring some sort of action to be taken. Informational warning lights are either green or white and typically indicate a system is in use. Red means stop as soon as it`s safe. Amber means that action is required.
The brake warning light is very serious. When you see it come on, check to make sure your emergency brake is off, then stop driving as soon as you get the chance. If you are running low on brake fluid, your brakes may stop working altogether.

My hazard light came on by itself in my car I have a 98 lexus GS300 all other lights working it went off for a while but came back
ANSWER : Hello,
This may suggest you have an internal wiring problem, a short or possibly a faulty flasher relay that may be causing your hazard lights to come on intermittently. The flasher is an electrical component that allows the lights to flash on and off as they are designed to when needed. As electrical current is applied to the relay, it causes it to power on and off producing the clicking noise you hear when it is flashing on and off.

My dash board don’t work my front light work when I change my light into high beam and my back window won’t go down
ANSWER : As unfortunate as it is, your vehicle would be considered flood damaged. Diagnosing electrical problems in a flood damaged vehicle is nearly impossible. This would take many hours or even days to determine which wiring harnesses and circuits have been affected. Then nearly all of the wiring under the dash would likely require replacement as well as many sensors and switches. On a BMW vehicle, the amount of wires and switches are likely more than that of a lower end vehicle. Due to the inefficiency in cost, you would likely be able to purchase another BMW like yours for less than what it would cost to fix your car. Many insurance companies would consider this type of damage to total out the vehicle unfortuantely.

No dash lights, back right tail light is out, no parking lights. Brake lights work though as does head lights.
ANSWER : Hi there. In many cases, when you have electrical problems like you’re describing, it’s caused by multiple electrical component failure. It’s likely that a few electrical relays are not working; especially if you have systems that utilize the same components (such as your brake light and tail lights). I would recommend having a professional mobile mechanic come to your location to complete an electrical problems inspection first, so they can pinpoint what is damaged and recommend the right repairs.

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.

Okay so when I turn my lights on at night my brake lights do not work, when I don’t have my lights on they work fine.
ANSWER : Hi there. Based on your inquiry, it’s highly probable that you have a damaged light switch or some electrical fault inside the turn signal relay. However, it’s also possible that the brake switch above the brake pedal could also be the source of your problem. Due to the fact that multiple electrical components might be causing this issue, it’s a smart idea to first have a professional mobile mechanic complete a brake lights are not working inspection, so they can determine what’s causing all of these issues and recommend the right repairs.

my check engine light came on a few weeks ago and said it was coolant issue light went out and a few days ago it came back on
ANSWER : Your vehicle has less than 60,000 miles and inasmuch as you mention a possible fault in the engine cooling system, you should check for warranty coverage under Chrysler’s 5 year/60,000 miles powertrain warranty. If you are not covered under the manufacturer warranty, I recommend you request an overheating diagnostic from YourMechanic simply because a car that is overheating is essentially inoperable. You will ruin the engine if it gets hot enough, by warping essential engine components, so overheating has to be resolved before the issue with the electronic throttle is addressed. In your case, inasmuch as the Check Engine Light (CEL) has come on as well, the Mechanic will download the diagnostic trouble codes that always set when the CEL illumuninates and use those trouble codes as clues to resolving the issue you are having.

All dashboard lights and tail lights do not work after driving through a lot of snow. Headlights work. And brake lights work.
ANSWER : Hello. We’ll be happy to help you. There are a few things that I recommend checking to discover why your lighting system is malfunctioning. The headlight dimmer switch should be checked. Along with the wiring harness above the right front tire behind the fender well cover. Also
the main fuse under the hood should be inspected because other people with your particular vehicle have had similar lighting issues if that fuse goes bad. It will be a great idea to check the rest of the fuses in that area too while checking the main fuse. Once the fuses are checked inside of the main fuse box then I would check the fuses inside of their interior fuse box. The interior fuse box should be located on the driver side of the dashboard near where your legs would be.

Battery light goes on when I start car then turns off, if I rev engine light comes back until rpms go down. Abs goes comes on/off
ANSWER : Batteries can die due to faults in the charging system so ideally a suspected "faulty" battery should be load tested before a decision is made to condemn it. The only exception to this rule is if the battery is already clearly "old" (greater than 5 years) but even then once you put a new battery in, as a replacement for a "dead" battery, you have to comprehensively check out the charging system. Diagnostic Trouble Code P0460 will result in disruption of the dashboard fuel gauge’s ability to accurately report your tank’s fuel levels. The fuel gauge readings may be erratic, or read somewhere off scale. Vehicles equipped with a low fuel warning light feature may also suffer from erratic low fuel warnings in the event of a code P0460. Unless the P0460 code has been reported alongside other trouble code, all of the vehicle’s essential systems should otherwise function normally. I would recommend that you request a check engine light diagnostic to first resolve the fault causing the P0460 code to set. The check gas cap light warning light could be due a faulty gas cap and/or small leaks in the EVAP system.
