Turn signal symbol will not illuminate in dash

Is there one of those mini bulbs in the dash for that light? Could have burned out.

 

Is the turn signal the same bulb as the hazzards

 

Odd, have a look for the flasher unit. The indicators work so the flasher must be working but there must be a wire on it to the panel bulb. If it is the same bulb for the hazards then it must have a diode in the line as a block to stop it back feeding the hazards. The same would apply for the hazards feeding the turn signals.

 

The hazard/flasher unit should be ok if the external turn lights are flashing. The left and right turn outputs from the flasher unit go to wiring splices which feed the lights and the dash. There are no dedicated outputs from the flasher unit for the dash alone. One of these splices also feeds the hazard pushbutton to make the button flash when you have pushed it. @Some Guy in the sky, does your hazard button flash?

Since the left and right turn wiring to the dash is independent (two wires), it's unlikely you have a wiring problem. Sounds like a dash issue.

To 360 owners... Do the green arrows illuminate independently when you are turning left or right? If they flash at the same time, there is probably a diode or two to prevent the left and right wiring shorting to each other in the dash.

The hazard button is wired up to directly the hazard/turn module on a certain pin to initiate the flashing. The dash is also hooked up to that same pin (on yet another wire from the flasher unit to the dash), but it's not clear from the wiring diagrams what this input does... if it is an input.... it could be an output from the dash?


Sorry, I can't remember if anyone told me if the red triangle on the multifunction display illuminates if you push the hazard button... I've asked this question a few times... or does the red triangle only illuminate if you have an accident? This may provide a clue regarding the internals of the dash to assist with faultfinding.

Neat diagrams but not showing a diode

 

My old e36 bimmer idiot lights are the replaceable mini bulbs. But the reading I did shows the 360 Inst cluster to be much more complicated.

I would call one of the shops that repairs 360 clusters.

 

Interesting. The wiring suggests it should. I know on my F355 which has the same setup, the light didn't flash until I replaced a faulty diode in the switch. Perhaps someone can independently confirm that the button does not flash on the F360?

Thanks for the feedback on the triangle. I'll try to modify my wiring diagram to show this. At least we know your hazard button is sending a signal to the dash. I don't think this signal directly causes the arrows to flash, but rather the button activates the flasher unit and that causes the arrows to flash. Anyway, at this point, it looks like the dash is the main culprit. Hopefully a simple bulb/LED change.

 

I've added a triangle symbol to my wiring diagram:

I'm still not sure if the purple/black wire between the dash and the hazard/turn module is multi-purpose. I understand that in an accident, the hazard lights are turned on. Maybe an earth signal is sent from the dash to the hazard/turn module to turn on the flashers on that purple/black wire? Anyway, that is for another day. Back to your problem...

 

Thanks for the update, Some Guy
