Left turn signal blinks fast (as if a bulb were out)..

Left Blinker fast and dim

I'm having an issue with my left Blinker. When I turn it on the left side blinks fast front and back. Also the front left is very dim. I checked the connections In the front along with the groung on the driver's side fender. Everything seems to be in good condition. The bulbs have been replaced. Also to note it when I tuen my hazards on the fronts are not in sync. They go back and forth with the left still being very dim.... The problem has fixed itself before but it's back again. Please help.

I just ran into this problem myself. My rear passenger side turn signal bulb was dead (and blinking quickly because of it). I went to the auto parts store to get a replacement which worked but the turn signal kept blinking quickly. What fixed it for me was swapping one of the original bulbs (for the brake light) with the new bulb I purchased to replace the turn signal.

Thank you Dave I'm on my second e30 and second fast right blinker three mechanics and no happy ending

I ussually dont look for handjobs from mechanics.

Yeah I figured it out. LOL

The bulb is just sorta lose in the socket. A wiggle and it works

So now my car it works 25% of the time lol

Clean your connector, takes 10 minutes, take off the bumper and clean it. Worked perfectly for me.

Well my front turn signal no longer works.. went to Oreilly today with 3.50 in change to buy the bulb.. but you can only buy a two pack. fml

Your turn signal stalk could have a worn spot too.. Besides being the turn signal bulb housings.

faulty turn signal relay. It is under your steering column. To make sure it is the right relay, turn the signal on and you can hear and feel the square black relay clicking.

So sorry to bump, but I have same problem.

Left turn signal blinks fine

Right turn signal blinks... just twice as fast as left one. Driving me nuts, and just started today.

Any thoughts?

my turn signals no longer work the relay made a buzzin sound and they stopped working and made my check panel cut out

He Searchs He scores!

Would any of this affect spark or fuel? Tonight my left turn signal started blinking fast and then my I had no power above idle. Turned on the hazards and they started flashing fast too.

Got pulled by our local police and while I idled waiting on officer friendly, all returned to normal.

Quick fix for the lazy:

I was having the fast blinking when all bulbs were good. This is on my crap parts car, but i needed to pass inspection. I was in a rush and didn't feel like taking off the bumper to clean/ rewire the ground.

I soldered a wire to the side of the bulb and ran that wire to ground. Works like a charm.
this would be a good tester to find your bad ground as well.

Little more detail- Your turn signal is using your parking lights as a ground. The current is traveling from the turn signal switch, through the turn signal filament in the bulb, then through the parking light filament of the bulb, and through the rest of the parking lights in the car to ground. The reason the parking light filament is the one lighting up is because it is the highest resistance point in that circuit.

To show it another way, put your parking lights on and hit the hazards. What will happen is the light will go dark every time the turn signal is supposed to be on because there is +12v at the parking light side of the bulb instead of the path to ground provided by all of the other bulbs from earlier. +12v on both sides of the bulb results in a net difference of 0v, thus no light.

What is broken on your car is the ground, which is supposed to be connected between those filaments.


Too many people have problems with turn signal issues.... That and if your rear turn signal bulb were to blow, your car would do some stranger stuff, like having the green arrow on the dash light up with the parking lights.

Damn sparky. +1 I would check all the connections in the light housing, if this doesn't work, its possible it could have leaked inside the light and corroded. If its not one of these two than its gonna be a real pain in the ass.
