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.
The directional signals and the emergency flasher each have their own flasher unit. They are the same type of flasher and should be beside each other under the dash.
There is two flashers involved, one for the signals and one for the emergency flashers. Perhaps you changed the wrong one.
Some cars have two flashers, one for the signals and the other for the emergency flashers. Be sure you replaced the right one. Also check the fuse the bulbs and lastly the signal switch.
turn signals and emerg flashers work off a flasher can. go to any auto store and buy a new one they are cheap and easy to replace
4 way flashers and turn signals both have a "flasher can" in the system to make the lights flash the turn signal and 4 way flashers are controlled independantly of each other try replacing the flasher can for the 4 way flashers it is obvious that the bulbs are ok because they work on turn signals
Not sure what vehicle you have but with most vehicles the signals and emergency flashers are separate circuits. Each have there own fuse and flasher. Check fuses, bulbs and flashers. If all checks okay it may be the signal switch at fault.
The bulb is bad. Turn signals and flashers use different bulbs.
The turn signal switch in the colum could be bad COULD B the TurnSignal switch OR the Flasher 4 the Emergency FLASHERS (because there is 2(two) Flashers & the Brake light Switch on the Brake pedal could B Bad.(turnsignals Have there OWN Flasher) the emergency flasher switch has 3 electrical contacts.sometimes they overheat and melt into the red flasher switch deforming the whole switch.unfortunatly the whole blinker and flasher needs to be replaced.
You probably replaced the emergency flasher, so remove it & try your flashers; if they don't work, reposition the flasher & try your flashers. If they work now, then try to locate the turn signal flasher (ref. repair manual). Or...heaven forbid, you have a short or ground in your turn signal wiring harness (somewhere), where only an ohm meter and knowing how to use it will locate it. Good Luck!
Most likely you have a short in the system. If you have a trailer connection that is the first place I check,then I would check the turn signal bulbs for a corrosion bridge. Remove bulbs one at a time and operate the turn signals to eliminate the culprit. I ended up taking the car to the dealer. It was a faulty emergency flasher switch......$101.00!
Check under the hood near the battery, there should be a black rectangular box with a lid that flips open. This is the power distrobution box. Your relays will be in there.
