my blinkers stopped working today. also the emergency flasher won't flash. I tried changing the flasher. didn't help. I noticed that when I pull out ( turn on) the emergency flasher knob and put the turn indicator in the turn left or right position and step on the brake all at the same time, both blinker indicator lights on the instrument cluster come on and stay on without blinking. the turn signal switch is newly installed. I've been called many things but never an electrician. please help.
Lets get rid of the useless symptoms first.
1) The turn indicators are connected to the front turn lights only. That way they don't come on when you step on the brake.
2) The hazard switch connects all front and rear turn lights together (including turn indicators) along with the output from the hazard flasher when the switch is on.
3) The brake light switch over rides the hazard switch. In other words, the hazard circuit causes the 6 bulbs to flash because the flasher is turning on and off. The brake light current is constant as long as the pedal is pressed. The brake light current will be shared between all 6 bulbs when the hazard switch is on making the turn indicators light up solidly.
There are 2 flashers, turn signal and hazard. Turn flasher has a blue connector. Hazard power comes from fuse #5. Turn signal power comes from fuse #2.
