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 ...

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.

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.

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, ...

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 ...

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 ...

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

How 11-pin flasher relays work internally. See this wiring diagram: It is for the BOSCH 0 335 210 250 flasher relay (same as yours, only for 12V). The diagram shows the internal components of the device logically (physically speaking, there are some more inside). How to connect 11-pin flasher relays. According to the above diagram, this is how you ...

Almost certainly a poor connection within the bulb holder. You might be able to clean up the connections within the holder with a fine bit of sandpaper or "wet and dry", then adjust them with a tiny screwdriver to improve the contact, but it's probably easier to get a new unit...

You can try to look for a battery drain as shown in this video by Scotty Kilmer. If you find any drain in the battery you can fix it and this may solve to whole problem. EDIT: In the video Scotty uses a test light (that you can buy in AutoZone for about $10) or a 1 Ohm resistor rated at 10 Watts and a voltmeter (In case you have one lying around, otherwise ...

This usually means that one of the left bulb indicators has failed. Inspect front, rear and side indicators with the indicator stalk engaged in the left position and replace the offending bulb.

Take a look at the wiring diagram below. The important clue is you said the middle brake light isn't working. The CHMSL (Center High Mounted Stop Light) works only from closing the dedicated relay. This signal provides power to the lamp, and also instructs the engine and transmission control modules that you are braking. Unfortunately, this function is ...

On our '07 Cobalt, (1) I have the same non-canceling turn signal problem. I believe it's a mechanical issue. This guy says he has a fix, and an explanation. (Long, lots of pix, I'm not going to quote it ... so, -1 for me.) (Additional info: Something I read (the owner's manual?) suggested Chevy had tricked up the switch, so it won't cancel on lane ...

There is a separate fuse and a separate relay. You'll need to check both, and I hope the relay panel is a little easier to get to than it is on the MKIII, because that's a real treat. Check the fuses first, but a fuse isn't a wear item. They shouldn't blow unless something else is wrong as well. If it is blown and it blows the replacement fuse as well, ...

The life span of an incandescent light bulb is up to 50 times smaller than the one of an LED (in reality you can expect up to 1500-2000 hours out of an incandescent light bulb, but usually these numbers are highly overrated) However, choosing an incandescent light bulb might be the consequence of the following: Incandescent light bulbs tend to be really ...

Have you checked the bulbs in the turn signal lamps? Depending on the design of the flasher unit, one or more failed bulbs might mean there isn't enough current flowing to make the relay operate, and so it won't flash. (newer solid-state designs will flash much faster when a bulb has failed)


1

This isn't an entire solution, but your test of the hazard lamps leads me to believe the problem is within the following diagram... and most likely, from the view of my sofa, the multifucntion switch "stalk". @rpmerf's comment suggestion is the way to pursue evaluation of this suspect switch. I would stil double-check fuse #20, as a failure here (even ...

If you are lucky, there is a separate flasher for the emergency flashers that uses a similar relay. If so, just swap them and see if the issue is fixed. Or you may swap one from another car, just to test it.

The indicator lever is probably spot on for the issue. There appears to be a triple-square fastener which attaches the steering wheel to the column. The guy in this video on air bag & steering wheel removal says you can get away with using a T55 Torx head to pull the fastener. Other than that, it appears the job requires T20 & T25 Torx drivers. In ...

I've read in this blog that if you place the DRLs away from the turn signal, then you would not need to turn of the DRLs when turning. I agree with this approach. Cars lose a lot of style points when they seem lopsided with one part of the DRLs turned off. In fact there are many cars that do not have this issue. I would go one step further and say that ...
