Turn signal problem
A couple weeks ago I noticed that my right turn signal was clicking faster then my left turn signal . To this day it's still doing the same thing then recently my right rear turn signal doesn't flash or blank anymore whenever I use the right turn signal. All of the bulbs is working because when I turn on my headlights I can see the whole tail lights light up . Do you know why my right turn signal isn't flashing or blinking ?
My car has 72700 miles.
My car has an automatic transmission.
Experienced mechanics share their insights in answering this question :
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.

Answer: The most common problem is a shorted light bulb causing trouble, an electrical short in the signal switch, or bad flasher relay.
The good news is that all of these symptoms point to two possible issues, a bad turn signal relay or a dead bulb. If the signal blinks really fast, you have a bulb out on that side. If it doesn`t come on at all or doesn`t blink, you`ll need to replace your turn signal relay.
If both lights are not working, this is likely a sign of a blow fuse or a dysfunctional flasher. This could also be due to a corroded socket or damaged bulbs, which are a slightly more complicated issue.
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.
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.
If the blower and turn signal issues started at the same time its very likely there is a short in the wiring harness somewhere. When shorts occur they will blow the fuse as the circuit is getting too much power.
If the turn signals light up, but do not flash, it is time to replace the flasher. If there are no turn signals on either side, check the fuse as it may be defective. Another problem is both turn signals on one side not working. This could indicate bad bulbs or bad ground in both housings.
There are a few reasons why your hazard lights might be working but your turn signals are not. The most common reason is a blown fuse. Check the fuse box for a blown fuse and replace it if necessary. Another possibility is that the bulbs in your turn signal assembly may have burned out.
Testing the flasher unit
To test the conventional type of flasher unit, use a circuit tester between the terminal marked B on the unit and the earth. Turn on the ignition . If the supply side of the unit is working, the bulb should light. If it does not, look for a break in the wiring between the unit and the fuse box.
Signal relays are essentially electrically operated electromechanical switches that control the flow of current in a circuit. They work by using a magnetic force, produced by a control current running through a coil near the contacts, to move internal moving parts or contacts between open and closed positions.
Green is for the right turn signal. Yellow is for left turn signal. White is ground, and brown is for the trailer`s taillights.
How Your Turn Signals Work. The turn signal circuit is pretty standard within most vehicles. Power for the signal runs through a fuse from the battery to the turn signal relay. The control circuit completes when you move the signal arm up or down to activate your right or left signal.
On most cars, the turn signal lever is located to the left of the steering wheel. Shifting the lever up indicates a right turn and shifting it down indicates a left turn. Your turn signal should turn off after a turn or a lane change, but if it does not, you should turn it off manually, as soon as possible.
If the turn signal stays solid on the dash instead of blinking, that typically indicates a failed bulb. If the bulb is not the issue, check the connector at the turn signal for both power and ground. It looks like both turn signal bulbs share the same ground point, but the ground side wiring could be faulty.
Look at the fuse wire. If there is a visible gap in the wire or a dark or metallic smear inside the glass then the fuse is blown and needs to be replaced.
In the world of DC electronics, the accepted wiring convention is that the red wire carries the positive voltage, and the black is circuit ground. Usually the red is marked as + (plus) and the black is marked as – (minus).
With a three-way switch, three wires connect the pair of switches—two black “traveler” wires and a third “common” wire. When the circuit`s power is turned on, any of these may be “hot,” depending upon how the switches are toggled.
Springs will loose resiliency with time. Relays can also fail due to poor contact alignment and open coils. Selection of the proper relay type for a given application is the most significant factor affecting relay reliability. Many poor design practices are used when designing them into circuits.
The Bulb Is Burnt-Out
One of the biggest causes of a faster-than-usual turn signal might be a burned-out lightbulb for that side. A burned-out lightbulb could be an essential cog of an annoyingly fast blinking turn signal that doesn`t stop since the bulb is sending an irregular current in the indicator system.
A faulty switch can be one of the main reasons why the turn signals don`t work. It is also good to check the parking lights, which usually utilize the turn signal bulbs. If the parking lights and hazards come on, but that side doesn`t illuminate when you hit the switch, then it`s a circuit problem.
Flashers will have two or three pins as opposed to the four or five of a standard relay. With a two pin flasher, the pins would be connected to power and the light circuit. With a three pin flasher the additional pin would connect to an indicator light to let you know your flasher is on.
In most cases, this will be 12 gauge, which will service 25 amps for 10-12 feet in length, which is about the right length for a door window to the power source. The more common smaller gauge wires are what you will likely deal with the most. 22 gauge is only good for signal, like sensors.

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.

Electrical Short/Power dimming when brakes pressed. Turn signal fuse blowing. 1980 Dodge B200
ANSWER : Hello – you have electrical problems for sure, possibly more than one. A short in the steering column wiring seems likely. This problem can be diagnosed by connecting an ammeter to the positive (red) battery cable, observe the current drain (likely less than 1 amp), then, one at a time, remove each fuse, check to see if the current drain has dropped to near 0, then reinsert the fuse. start with the brake/turn signal lighting circuit. This process should identify the faulty circuit in most cases. The specific components on that circuit can then be checked for current drain problems. A professional mechanic, like YourMechanic, can come to your location, and perform this procedure for you, and replace/repair the failing component.

When parking lights activate, left turn signal independently stays on
ANSWER : Hello there, thank you for asking about your car. If the turn signal stays solid on the dash instead of blinking, that typically indicates a failed bulb. If the bulb is not the issue, check the connector at the turn signal for both power and ground. It looks like both turn signal bulbs share the same ground point, but the ground side wiring could be faulty. If power is not getting to the bulb, the problem could be the turn signal switch or wiring. I recommend having a professional, such as one from YourMechanic, look into this problem for you and replace the turn signal bulb or switch.

Engine turned off but inside of car still on, now engine won’t turn back on.
ANSWER : Hi there. The symptoms you’re describing with your boyfriend’s 2002 Grand Cherokee appear to be related to a broken or worn out ignition switch or relay. The ignition switch on the inside of the steering column is attached to multiple electronic connections that send signals to a relay box; which in turn, sends the signal to the individual components. The issue could be related to the ignition switch, the relay, or any of the components in between. If you want to have the fault pinpointed in person, I would have this starting issue inspected by a trained professional to ensure that the correct repair is made.
