Turn signals.flash too fast or not at all

What does the rear turn signal do? If one of the signal lights are not working, the other will blink faster. With the headlights off the turn signal bulbs ground through the light holder. With the headlights on the running lights are using the same ground circuit. Make sure all bulbs are good with a good ground.

If the front and rear bulbs flash fast also, replace the hazard switch or you could live with it. As they are working. If one doesn't work, check grounds. I just run a new ground, much easier than cutting open the harness to find the break.

Make sure all the bulbs are working in the turn signal. Some front turn signals will use two or more bulbs per side. If any one of these bulbs are burned out it will cause the turn signal to flash at a fast rate. It also could be a bad control lighting control switch a.k.a. multi-function switch.

Take the bulbs out and see what it does.

Maybe is small one.you miss.

check to see if the front or rear bulb is burned out most of the time one bulb burns out causing a faster flash on that side.

fast flashing signals mean that one of the bulb are not flashing, usually a burnt out signal bulb. just turn on the signals and check for what bulbs don't flash. replace bad bulbs and then chack again.

you said lights are working fine on rear but generally when they flash fast there is a turn signal light out on the side they flash on. Did you look at the turn signal light on the front of the vehicle?
