have you check all the bulbs? if one of the bulbs are bad they will light up, but will not blink.
Probably the signal flasher relay, but be sure all the bulbs are okay.
check your bulbs, this happens when a light bulb is burnt out good luck
loose bulbs
Your fuse box cover should have a label inside showing which fuse is for which componet. If you don't see it on the fuse box inside the car, try looking at the one under the hood. I don't think it's under there for the turn signals, but the headlight fuses are under there. If the back signals are working, it's probably not the fuse, but burned out bulbs in the front. You can tell if the front bulbs are burned out just by looking at the turn signal indicator on the dash. If one of the bulbs is burned out, it will blink real fast on the dasn indicator. I hope this helps shed a little light on it for you.
check light bulbs in both lights
it usually means one of the bulbs are bad. replace the front or back one, which ever has broken filament, and should blink fine after.
Some of the older cars would blink fast when one of the signals on the front or back on the same side would burn out but i don't know about both of them blinking fast. You might see if you have a coulple of signals out. It might just be a corroded contact on the bulbs.
If your blinker is blinking at a faster rate than normal, it usually means that one of the bulbs is out. For example, if the left turn signal blinks faster than usual, check either the front or the rear left turn signal. If both turn signals seem okay, check the front left parking light. (this is the front orange light that is on when your headlights are on)
Normally this happens when one of the bulbs is burnt out. Make sure all bulbs are working.
There's a turn signal or running light out on that side, either front or rear. Turn on signal, get out and look. If both turn signals are working, chances are its the running light.
For your front porch light, it is recommended to use LED light bulbs. They are energy-efficient, long-lasting, and provide a bright and clear light for your porch.
