Experienced mechanics share their insights in answering this question :
Hello there, installing aftermarket components like the stereo do not always work out properly on your 1998 Mitsubishi Galant. When installing aftermarket radios with the adapter harness all of the wires should have a place to go and all components should function after the installation. Likely problems is a damaged wiring harness, improper adapter, or a shorted wire. At this point this is a job best left to the professionals who will be able to repair the wiring. A qualified technician such as one from YourMechanic will be able to diagnose your electronic issues and make any repairs required to resolve them.

How to Identify and Fix Common car Problems ?

Sometimes when a taillight lens cracks or breaks, it can allow moisture to enter the lens and cause a short circuit, blowing the fuse. Burned Out Bulbs: In the case where only one of your rear lights appears to be out, the cause is most likely a burned out bulb.
If you have a malfunctioning tail light, it could be a matter of a blown fuse. The fuses work with your car`s electrical panel and if they`re blown, it can cause several lights to stop working. Replace the fuse and see if this helps. Another issue may be related to your wiring.
Chances are, if your brake and turn signals have all gone down, your fuse is as good as gone. You can find your car`s fuses in the fuse box, often underneath the hook or on the kick panel inside the passenger compartment. Your car manual should tell you which fuse is for your brake circuit.
Bad Socket. If you have a single brake light out and the bulb is good, then the next step is to check the light socket itself. Brake light problems can include a socket whose connections are dirty or corroded or one whose wiring has become worn to the point where it`s only making an intermittent connection.
Check the fuse.

A blown fuse usually causes both lights to go out. On newer cars, the tail lamps can be fused separately and/or each bulb or shared circuit can be fused. A fuse can be blown due to other problems, so you`ll need to check more than just the fuse, but it`s the right place to start.

It is a 15amp fuse that powers the stop light switch on the brake pedal. The brake light switch sends power to rear brake lights.
Like all of the lights on and in a vehicle, turn signals rely on a fuse. When the fuse blows, electric power to the turn signals will be shut off entirely. Burnt out bulbs: As with all light bulbs, turn signal lights can burn out and die.
It is usually located under the driver`s side of the dash, and is wired in-line with the turn signal lever and hazard switch buttons.
If half a strand is working and the other half is not, you probably have a loose or broken bulb. Start with the first unlit bulb and work your way down, wiggling them to check for looseness. If it flickers, that`s your cue to replace it.
This could be on the switch itself, at the circuit breaker panel, or in a pass-through wire connection in the wall box or ceiling box. By far the most common problem is a loose wire connection at the switch itself, which is subject to constant on-off usage. Less commonly, a light bulb socket may go bad.
No. Fuse is a conductor in normal circuit. So it`s without any direction or polarity and orentation. The fuse will cut off the current path due to the high temperature melting point of the fuse, regardless of the current direction.
It is also wise to replace both headlamp capsules, as well as brake light and taillight bulbs in pairs simultaneously, as both have the same age and deterioration. In all likelihood, the opposite lamp capsule has degenerated considerably and will burn out fairly soon, as well.
Color Codes for Trailer Wiring

A good place to start is by getting to know the industry-standard color codes for trailer wires. Green is for the right turn signal. Yellow is for left turn signal. White is ground, and brown is for the trailer`s taillights.

Tail lights are wired to the same switch that turns on the head lights, making them function easily. If you have automatic lights, the tail lights will turn on when your vehicle is on. If you use a switch to turn your vehicle`s lights on, the tail lights will illuminate once your head lights are on.
Like all fuses, the brake light system fuse can be found in the power distribution center, which is under the dashboard or tucked away underneath the hood. Never heard of the power distribution center? It`s just the technical name for a fuse box.
In North America, since 1986, all vehicles feature a third brake light. Legally, this is called the Center High Mount Stop Lamp, CHMSL for short, but informally called center brake lamp, high-level or eye-level brake lamp, cyclops brake light, or safety brake lamp.
Ship Switchgears is a manufacturer of Fuse Holder and Carrier to suit the bolted type HRC Fuses. Housing made of electrical grade Bakelite powder material having High Electrical and Mechanical Properties, Non Inflammable, Fire Retardant and Self Extinguishing.
Diode Dynamics Tail as Turn® modules are plug-and-play units, that illuminate your main taillamp as both a brake and turn signal. By doing this, you can put your modern LED tail lamps to full use, and eliminate the older incandescent turn signals.
A fuse is always connected in the live wire of the circuit.
A turn signal relay (also known as a flasher relay) is the electronic device that controls your car`s turn signal lights. The clicking sound when you activate your turn signals usually comes from the turn signal relay.
The indicator flasher relay is a traditional car component and has been in use since decades, precisely regulating the turn indicator`s signalling system. The typical flashing enhances the signalling effect of the yellow lights on both sides of the car.
Push the point of the tester through the wire insulation behind the socket to make contact with the wire. The tester should light for two of the three wires (the ground wire won`t light). If it lights for two wires, the wiring is good. Simply replace the socket.
The brake light system is a simple on and off exterior lighting system which is controlled by a brake light switch located near the top of the brake pedal. A simple wiring circuit is connected to the car`s BCM and then onto the rear brake lamps (older cars do not use a BCM – body control module).
A damaged circuit breaker is one of the notorious causes of a partial power outage in many homes. The damage is commonplace during an overloaded electrical circuit or a short-circuiting from a faulty appliance or wiring. Diagnosing the problem isn`t difficult since a blown fuse or a discolored switch is enough clue.

the most relevant questions and answers related to your specific issue

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.

Right, Rear Turn Signal Not Working but its a New Bulb
ANSWER : It only takes a small amount of corrosion to interrupt the flow of current. You probably just have a dirty light socket. If you get a small strip of 400 grit sandpaper and rub it on the contact surfaces in the bulb socket, that will probably get you working. If that doesn’t do the trick, you have to get a test light or a meter and go hunting for the interruption. If you would like to have a technician do this for you, you can contact Your Mechanic and have one come to your home or office and check out your turn signals for you.

Turn signal problem
ANSWER : When you turn on the turn signal on the right side do you get a light in front and rear come on but not blink? Do not have headlights on at this time. Replace the right front turn signal bulb if it does not light. Then replace the left rear bulb with correct bulb for vehicle since using wrong bulb will cause fast blinking and a bad bulb will can cause no blinking at all.

Side markers will not turn off, turn signals not working
ANSWER : There may have been unknown damage caused when the previous service was done. It may be necessary to replace the circuit board as every copper track is important for proper operation. Failed switches or relays can cause devices to activate and stay on if there is an internal fault. This concern may require some extensive hands on work so consider hiring one of our mobile experts to come by and check this electrical issue out.

My rear left turn signal will not work and I have replaced the bulb and checked the fuse.
ANSWER : Hey there. The most likely problem is the bulb holder / socket itself. It may look fine but probably has a crack or break internally. Also possible (but rare) is the circuit board within the tail lamp housing itself. I recommend having a qualified professional, like one from YourMechanic, inspect the lights in person in order to have this corrected properly.

Chrysler car, replaced turn signal switch and flasher relay and turn signals still do not come on either right or left, no turn si
ANSWER : Hello, thank you for writing in. If the electrical components are all working individually, then the issue is likely relating to the wiring between them. The best way to trace the issue is with a voltmeter. In doing so you start with the power supply starting at the fuse box and work your way down the circuit. When you find where the voltage cuts off, you will have found the wire or component that has failed. You will want a wiring circuit to help you through this process. Often when after market components have been installed around the wiring it can become damaged. Double check any of these areas. The switch and steering column will both need to be tested as well. For more help with this type of electrical testing, contact our service department.

My car shuts off when I turn on the light or even the turn signals please help need this car to get to work
ANSWER : Hi there. This type of electrical glitch can be very difficult to pinpoint or diagnose without a physical inspection. However, in general, the most common causes of this issue is an exposed electrical wire within the ignition system. It is best to have a professional mechanic complete an electrical problems inspection first in order to correctly diagnose and resolve this issue.

How can I fix my front right turn signal?
ANSWER : A fast flashing turn signal indicator, is a sign that you have a turn signal bulb not functioning. In your case, I would double check the right front bulb to ensure it is a good bulb, and that the connector has no signs of corrosion that could prevent proper operation. It can also be a broken wire or bad connector. A certified technician, like one from YourMechanic, will be able to pinpoint the cause of your turn signal problem and perform any repairs needed.
