The main purpose for this is so other drivers can see your turn signal. The LED lights are so intense, they do not allow the oncoming driver to be able to see the turn signal. By turning the LEDs off, it becomes readily apparent.

Yes you can often repair turn signal flashers!
A variety of things can be wrong: here's one of them. Solder joints on the relay printed circuit boards are especially vulnerable to stress cracks, due to the clicking motion day in and day out.
Take the case off the relay and use a jeweler's loupe to inspect for hairline cracks, especially cracks those that ...

I can think of several reasons straight away:
Cheap
Easy to replace
Have a very distinctive click that makes it obvious when they are on, and when a bulb has failed
Are very well understood
Anyone can fit one without needing to understand much about electronics

This is symptomatic of a loose or poor earth on the lamps. It may be either the front or the rear earthing point. The other item to consider is the indicator/hazard unit, it may be starting to fail.

On the Expedition the hazard, lower brake lights, and turn signals all route through the multi-function switch.
Gain access to the multi-function switch connector and back probe the light green wire while pressing the brakes.
Does it have power? If it yes back probe the light green/orange and orange/light blue wires while pressing the brakes.
Does it have ...

Usually the breakage is some small plastic part that you're not going to be able to reasonably repair. Typically a whole replacement unit can be had pretty cheap from a junkyard anyways. Normally not worth a repair effort.

I'd check the ground strap/contact to ground from the blinker to the chassis first. Chances are there's a problem with it an it "grounds" via another bulb when you also apply the brake.
Using a multimeter, check the resistance from the ground on the bulb holder against the chassis first, then check blinker ground against both contacts for the brake light. ...

The front light bulb has failed. Simple fix!

You probably need to change the flasher unit to match the load of the LEDs. If you can't find a custom part specially made for this, I suspect you can do it by replacing a capacitor inside the unit. This should fix the flashing rate, but I'm not sure whether or not it would fix the indicator.
Honestly, since this is just a turn signal, you might just be ...

Some cars have a separate flasher relay for the Hazards - if that's the case then you might have a failure of the primary flasher relay?
The signal initially not turning off suggests a possible failure of the switch though - It might be worth disconnecting the switch (there's usually a connection somewhere under the column) and testing it separately? I'm ...

For the remote entry receiver see number 11 in the diagram below.
The interior key antenna is located under the center console number 13 and inputs to the body control module seen in number 1 of the diagram.

Your BCM receives the signal
Nissan uses what is called a BCM or body control module.
The BCM on your car controls the following
Security (key fob synchronization, door locks)
Turn signals
Wipers
Audio System
Lights (internal/external)
Anti-lock brakes
There are other attributes as well not on my list but to answer your question, it's the BCM.

A multimeter is going to be your best bet as, depending on exactly what the cause is, you may have one of the following:
a partial short circuit
a partial open circuit
a faulty relay
You will need to follow the wires to find the physical problem. The good news is that it is likely to be near the back, as closing the trunk must have jarred something ...

The way most indicators are set up is that the load on them affects the flash rate (those older models used current flowing through a bi-metallic strip: the bulb current heated the strip which then broke the flow of current). Modern indicator circuits are often much more electronic, but the same setup is used to make it obvious to the driver what the ...

There are two filaments inside a turn signal bulb. One of them is dim for the park lights, the other is bright for the turn signal. The bright filament can break on one end and land on the dim filament. Anytime the parking lights are on it makes both filaments light. The turn signal can still function depending on where the break in the filament is. This ...

This sounds most likely to be a fault in the switch in the indicator stalk - normally you have a physical linkage which keeps the turn indicator flashing while you turn a corner, then it releases as the steering wheel straightens.
I can imagine a couple of ways this could fail and allow the spring in that mechanical return to perhaps trigger the right ...

Two things.
First, you can almost guarantee with the blinker going fast one of the bulbs are out. This might include any of the small bulbs which are side markers as well as the main lights which are front/rear. Look around the "good" side of the vehicle with the blinkers on to figure out where the small bulb might be, then look to see if it is flashing on ...

Generally, when looking for harder to find parts such as this signal light my first thought would be to check online retailers like Rockauto, etc. However, this turned out to be a no go as this car has very few parts available probably due to its popularity like you stated. After this I usually hit up eBay just to see what can be found. Interestingly though, ...

Assuming that your Jeep has the same sort of clicky flasher that most cars do then you will need to add the resistor to make the circuit work. The reason is that the flasher is based on a thermal mechanism, it actually heats up a small wire that then twitches to break the circuit. When it cools it relaxes and closes the circuit this then repeats to make ...

The last time (many years ago) I changed out a turn signal switch it was a PITA because of all the anti-theft devices wrapped around the steering column. By the time I got to the switch I was cursing up a streak and I never did get the thing back together right. Never again. With airbag systems on the steering wheel it can only have gotten worse. My advice ...

Check your earth/grounding points for the lights. Lights illuminating when they're not supposed to is a classic symptom of a bad earth.

Since its sporadic it is more annoying to troubleshoot, but you should be able to check for voltage after the combo switch and see if that is consistent. There should be continuous voltage to charge the flasher (from my understanding of how the flashers work) to charge the flasher. If there is stable voltage when the blinker stops blinking, then there's ...

Blowing a fuse is a pretty good indication of a short circuit. If you have a DMM (digital multi-meter) try some basic tests:
With the fuse out, read between the prongs of the fuse socket and ground (a nearby screw or other bare metal) with the meter on a DC Volts scale (20 VDC is common) to identify the hot side of the fuse. Once you know which side is hot,

It sounds like you could have a faulty turn signal relay. A relay is a piece of electronics which flashes the light on demand. They are generally cheap and easy to replace, so I would start there. If that doesn't solve it you could have a connectivity problem in the wiring which would need to be traced.
It could be the relay has some sort of contamination ...

Forgot about this question. Anyway, replacing the bulb fixed the issue, though unlike as Larry suggested, both filaments were intact. Also unlike as Drake suggests, the bulb was of the correct model. Still no idea what the cause was, but it's fixed now anyway.

I have also seen it from putting the wrong bulb in the socket - often done by another shop or parts store even. Of you've had one replaced, pull out the bulb and look at the bottom. Make sure there are the same number of 'nipples' on the bottom of the bulb as there are in the bottom of the socket.
When i worked as a mechanic, it was a very common problem i ...

Your blinker module is broken. This is on the left side behind the steering wheel. There is some mechanical part connected to the steering wheel. If you turn blinker right, some little tooth came out of this module. Then if you turn the wheel back, it touch the tooth of the steering wheel and release to blinker to neutral. Maybe if you build up this module, ...

It seems your multifunction switch is probably bad.
It should be fairly easy to pull this switch to inspect it. I found these instructions to gain access:
The turn signal canceling is part of the function of the 'multifunction switch'. This is a switch mounted on the steering column by 2 screws. Once you take the covers off, you can see the screws, ...

Check what happens when the hazard light is switched on. If hazard works correctly then the problem could be with the combination switch(light). It is better to get it replaced at the workshop is my suggestion

Replaced the socket, it seems to be working now. I ordered a new part from a dealer. The replacement procedure is easy: Pull the wire retaining clip with a screwdriver, remove the old bulb socket from the wiring harness plug, insert the new socket, replace the clip.
