Basically, there is a bi-metal strip, current flows through the bi-metal connection, this becomes hot while the indicator bulb glows, once its becomes hot the bi-metal strip will move apart as the temperature expands the metal, the indicator bulbs now has no current and does not glow. The bi-metal strip become cold and resets to its starting position, and the process starts again.
This flashers speed depends on the amount of current flowing in the circuit, (through the indicating bulbs) if say one bulb blows the flasher relay may start flashing quicker, this is because there is less current now flowing though the flasher and so does not get so hot, it's still gets hot enough to separate the bi-metal strip, but because it's not as hot it resets much quicker.
Some newer type relays still use this technique but have a third pin, which helps when a bulbs blow to keep a regular time interval. And some new relays have been designed to work with low current drawing bulbs (LED lights), these relays are generally electronic.
It has 2 different flashers. One for the turn signals and one for the emergency flashers.
you need to replace blinker can in your vehicle. the flashers and blinkers have separate flasher cans which is why your flashers still work but not your blinkers
Faulty hazard switch.
because there are two diffrent flashers 1 for the flashers and 1 for turn
this car may have separate flashers for the turn signals and the emergency flashers
It is normal for the emergency flashers to work with key on or off. You need to shut the e-flashers off with the e-flasher switch.
what do i try next? i tried a new flasher on the steering column. my flashers work, but turn signals don't.
I CANT GET MY TURN SIGNAL OR 4WAY FLASHERS TO WORK ,FUELS ARE GOOD. I HAVE A 98 LINCOLN NAVIGATOR CANT GET THE TURN SIGNALS OR 4WAY FLASHERS TO WORK. FULSE OR GOOD
No because they need power to work.
There are two different flashers on vehicles. 1 for the turn signals, 1 for the hazard flashers.
I found that it was a burnt out bulb
try turning on the emergence flashers then they will work i have that problem after i do that it seems to work
I think there are two different flashers one for blinkers and one for the flashers.
Replace the bulb- There are 2 filaments in this bulb. The brake and flashers work off the same line and the turn signal works off another. If this isn't it, check your fuse box.
u have two flashers on your car... one for blinkers and one for flashers.
We need more information. Never work? Come on and not blink? Do the 4way flashers work?
I believe the flashers are on a separate fuse than the blinkers, that is where I would first start to look, is the fuse box
Multifunction switch is bad.
i guess wait for a while then it does not turn just go
The signals and the emergency flashers have separate circuits, separate fuses, separate flasher relays. Start with checking the fuses, the bulbs, the signal flasher relay and wiring and if it still doesn't work it may be the signal switch is bad.
There are two relays, one for the emergency flashers, and one for the turn signals. Your turn signal flasher is defective and needs replacing.
bad fuse or there is a short in 1 of the wires under your dash
Replace the bulb on the one that doesn't work.
The turn signals on a 91 caprice do not work, the emergency flashers do.
