Peugeot 307 Left Indicator not working after bulb changes

Have a 307 a year and a half old and the left indicator went off last week.
On the dashboard upon signalling the indicator is flashing very fast. (The side and rear work fine).

I have changed the bulbs twice and at the beginning seem to work but then the same thing happens. I thought it might be the fuse but looking at the manual the nearest i can find to indicators is the hazard lights. These all work fine except for the left front one.

If the fuse had gone wouldn't they all go out.

Any help or advice please

Thanks

If the indicator bulb is failing this often it would seem that you have a fault in the car. Possibly vibration of the bulb, or an electrical fault.

Your car should still be under warranty, normally 3 years? If so take it back to the dealer and get them to fix it.

i have this problem on my 307. it's the bulb holder that if faulty. one of the metal connectors has burnt away. a trip to the breakers yard for a replacement.
