Turning light not working

[spadaco]

Hi,

All the problems with the car always happen just before the holiday!!

Since 2 days my front right turn light stopped to work! I said "doesn't matter, I will change the bulb (P21W) and all will be ok!!!"........Surprise!!! I open the front light and I discovered that the bulb was ok, I changed the bulb, to be sure, with a new one.....but the turning light is still not working!!!

What can I do? Any Idea?

Check for corrosion on the socket and/or connectors. A fairly common problem.

Same problem here. I changed both sides to even out, worked for a couple cycles, then off again. Then the other side!... what's going on?

To make sure, I sanded out the metal tabs on the socket, but not yet the metal tabs in the housing (but it looks good though). Are there a "Control Module" for the lights?

It is simple to with a voltmeter - either there is voltage there or not. If one light works and other does not then I doubt it is the control module.

[ManMN]

OK, that makes sense. I'll play with it again after work today.

There have also been faults with the electrical connector that hides in the fender. When you install the light assembly it can cause a misalignment and poor contact within the socket.

I'll try again and I'll report!! let's hope!!!

Hello Loren,

Do you have the pin-out of the socket? Kind of hard to check for the voltage without knowing which pin is what.

Thanks,

You are measuring where the bulb goes so there are only two connections. Brown wire is always ground on Porsches.
