Apparently this is a common problem with Citroen C1 where the indicators work, but the dashboard turn lights either do not work or become intermittent.
Like most people I went onto YouTube and the issue pointed to the steering wheel stalk switch which I duly bought from eBay, and after watching more videos on how to change this, I was very please with my efforts until I tested it and the issue was exactly the same!
How to Diagnoise
- Do both dashboard indicators come on when the Hazard Warning button is pressed and are they both stable when lit.
- If the dashboard lights are OK with the hazards but ‘flakey’ with the indicator switch, the problem is the steering wheel stalk and a replacement is about £18 and you will need a pair of bent long nose pliers.
Their are loads of YouTube videos on how to change the column switch and watched this excellent explanation: https://youtu.be/H3MQ8Ixwxow?si=G4r32EeSE6jmonJg
3. If the dashboard turn lights do not light at all or flicker or go very dim, this means the LED in the display cluster has failed or is failing, this was the case with me.
Instruction on stripping down the dashboard and changing the LED is here: https://youtu.be/vcVhkZm-138?si=Tqc9dxZNZn5V3RX5
Repair
The red circle shows the LED which has failed for the Right Indicator, the LED type is a surface mounted 1210 GREEN colour, (I swopped out the left LED while I was at it).
I bought 10 from eBay for less than £2, in preparation for changing them I also bought a 15w soldering iron with a fine pointed tip as these LEDs are tiny.
I already had a de-soldering suction iron from Aliexpress which worked brilliantly to unsolder the dashboard display to get to this point.
The LED is sat on top of a small screw and I found it a bit of a struggle as I didn’t realize how much my hand shakes, but managed it in the end 🙂
Everything worked fine when I plugged everything back together, BUT I made a mistake when I refitted the speedometer pointer, this meant removing the clear cover and pointer, turning the ignition ON, then pushing the pointer on the spindle at the zero MPH mark, I must have moved the spindle and after putting the pointer on, the servo speed motor couldn’t calibrate as it was hitting the milometer reset button.
This was an easy fix, but still a pain to do after I had though everything was working.
Hoe this helps somebody else.
