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

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 ...

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.

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 ...

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 ...

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 ...

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

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 ...

You can ground your test light at any place where there's a good ground. That might be a bare nut/both, off the leaf springs, on a rust spot on the bumper ... anywhere. There are two types of connectors I've seen for smaller trailers (4 way or 7 way). If you are using the 4 way, I've seen if you twist the two connectors together (work them back/forth ...

For cases where the culprit is not the switch, it could be the flasher relay in cars that have separate indicator flasher and hazard flasher relays. (Which is common for example in oldtimer cars and trucks that originally had no hazard flasher at all and then got an aftermarket one added after years.) How to check for a faulty flasher relay. To test if the ...
