My right turning signal is blinking like crazy when I use it. I meant it is in lots faster interval than the left signal. It happen occationally since Saturday but happened 5-6 times this morning. My left signal and emergency stop light (all left-light blinking) are working normally....

What could this be?

One of your 2 turn-signal lamps is out. Replace it. Because it's not drawing as much current as 2 bulbs would, the frequency of its blinking doubles/triples.

Thanks Sesh, but that is not the problem.
When I tried the emergency light, all signal lights are blinking correctly.... none is out.

my truck did that as an early warning to the bulb going out. I let it go a while then it eventually did burn out.

My C class had the same problem. It was an electrical issue. They had to replace a wiring harness and some electronics because it kept happening randomly.

Eventually my key stopped working as well and they had to replace quite a bit more to fix that. I'm not sure if they were related. I don't think so though.

My brand new C class had one electrical problem after another. I lost count on how many bad modules they had to replace before it was totaled.

yeah it's definitely just the bulbs...cmorosco i think you just had really bad luck with the electric system in that c class.

Just swap out all your turn signal bulbs...it's neither expenive nor difficult

DA_SURG,

If it stayed that way I'd agree but he said it keeps happening and then going away. Wouldn't it stay that way until the bulb was replaced if it was just the bulb.

I definetly agree I had major issues with my C class. I'm not sure it was bad luck though as I knew several other people with the same issues in their C classes. I learned my lesson on buying a first year car though.

It's not stay that way every time. This happens occationally only. Says 2-3 out of 10 right turns.
So, is it still the bulb? They all looks fine to me (all 8 of them, 4 left, 4 right, instrument panel, front, rear and side).

cmorosco, sorry to hear about your bad luck on c-class. I used it couple times for loaner car. Seems to be nice but they are some lemons out there!

Tempoct - it's a cheap solution [potential solution]. Could you try it out and let us know. I guess you could swap the signal from the left and see if it happens.

Hi,
I would try that during the weekend when I have time.
BTW, I have noticed that the fast-blinking is related to my steeling wheel position. If the blinking happen, I steer more, it would be gone. If I'm not, it will persist... or until I turn it off myself.
Weird...

New update. Front signal light is more dim...

When this happen, my front signal light is quite dimmer than the left one! When it works normally, both left and right are lit equally....
What could this be? The bulb seems like, but could it be the wire?? Which one should I look at?
Don't really wanna go another trip to the st(d)ealer...

After almost a week of bulb replacement and little contact cleaning, I'd never experienced this problem again.

Nevertheless, judge from physical view of the bad bulb, it looks perfect from inside out. Think we could be fool by this!

Thank you so much for this. Save me a trip to the dealer.
