Turn indicator won't blink
« on: December 16, 2013, 09:06:22 »
Had some repaint done on my car this summer - thus had the side indicator (the one on the side of euro models, not the front one integrated in the head lamp) removed. While all the other indicator lights blink happily on demand, this on just lights up permanently without blinking when the headlights are on (which they have to be also during the day here). I can only see one wire to the offending indicator light and this seems fine - when I remove it, the light just goes out. So I'm a bit confused as to what to do next, any ideas would be greatly appreciated :-)

Have I really stumbled across an issue so puzzling that nobody has any input as to what could be wrong? ;-)

I guess you just have to trace that one wire back, should go to the same place as your working blinker :-\

I am a little confused as to which light you are referring to: you've had the side marker light removed… the indicator lights blink happily on demand. So which one just lights op permanently if your headlights are on?

Anyway, if you've had a repaint done, then chances are:

  • you've developed a bad or intermittent ground connection
  • your painter removed connectors, and wired them up incorrectly.

I've had something similar before… two wires were swapped on one of my headlight connectors. When lights were off, blinker lights appeared to work. When lights were on, they did not. Essentially there was a short between the +ve of the headlight, and the -ve of the blinker. When headlights were on, applying +ve voltage to blinker created no current flow, hence no light.

I would therefore suggest that you have a bad ground connection. To be able to troubleshoot this, there is a useful document on this page of the Wiki: http://www.sl113.org/wiki/Electrical/Connectors (in the green text, the link: Connectors and Leads of the Main Wiring Circuit). Find the correct connector and ensure that all wires are connected where they should be. Make sure you orient the connector correctly when inspecting…

Thanks Peter and Larry - yes, it's the side marker light. Not permanently removed though, but only for the repaint. Will try and trace it backwards although I'm pretty sure nothing further in has been touched, but only the light itself :-)
