Usally the triangle is emergency signal lights, or flashers.
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.
It's the turn signal switch which is the culprit.
Could be the bulbs or the fuses or the flashers or the signal switch assembly
AnswerDefective emergency lights flasher relay.I had the same problem and I had to buy a new turn signal switch that you have to take off the steering wheel to get to it
The only thing that will work with key OFF is the brake lights,head lights and emergency flashers. Dome light will also work.
If neither signal light works, the flasher may very likely be the problem. The hazard lights and the signal lights work off different flashers.
Probably a wiring issue between the turn signal and the lights.
There are two flasher relays side by side. One is for the signal lights, the other is for the emergency flashers. They are the same relay so you can swap the two and see if the problem your having changes when you try to operate them.
It depends on the car. Some cars require that you turn on the turn signals to make the 4-way flasher work. If that's the case with your vehicle, make sure the emergency flashers aren't on. Otherwise, it's probably a problem with the turn signal switch.
check the turn signal relay in the steering colum, just before the turn signal switch the plastic receptors may be broke.
The emergency flashers and the signal lights are separate systems. Each has it's own fuse, switch and flasher relay. If your turn signals light up but don't blink I would blame the signal flasher relay.
