Turn signal intermittent failure

[deckman]

I have a 03 996 whose front left turn signal sometimes doesn't operate. When I first got the car this summer the bulb was relpaced to pass inspection. It's weird that most of the time it will work but sometimes it doesn't. Any ideas as to the cause?

Likely either a bad socket or corroded wiring.

Thanks Loren, will replace the socket and see if that fixes it.

Got the same thing, whats the socket and how do you tell if its the wiring ?

I have the same problem as well on 03 C4S.   I have swapped the bulb sockets between left and right and the problem is still on the left side, not the socket.   Flashers work except front left.   All other lights work fine.   It was intermitant for a while but now pretty soild fail.   Any ideas?

Time to get the ohm meter out and trace the wires back - both ground and power.

I had a similar problem with my 996TT after swapping bulbs. Turned out I broke the lamp housing when fitting the socket. The socket went back into the bayonet like mount but wasn't making good contact. Ended up replacing the housing with a used one.
