Hi everyone,
Firstly happy Halloween hope you are all keeping well.
I’ve been having a issue with the gauge cluster that I cannot seem to get to the bottom of! Issue was present when I bought the car but as I bought the car during the day I didn’t notice it and don’t have any information on when it stopped working and if it was as a result of any tampering but my gauge cluster is not illuminating, bulbs have been replaced, fuses have been checked, the dimmer switch has been tested using a multimeter and seems to be working, I’ve cleaned all connections with an electrical contact cleaner, All other lights in the gauge cluster work perfectly fine I.e EML, indicators, headlights on, full beam on, handbrake light, oil lights, all working fine, EXCEPT ABS light, the abs light does not illuminate ever, I changed the bulb with a known to be working bulb and abs light still didn’t illuminate when I turned ignition on and the rest of the dash lights lit up, my heater controls light up perfectly fine, ignition barrel light works perfectly, fog light button illuminates, it’s literally just the speedometer illumination and the abs light that refuse to work.
I’ve had the car seen by my mechanic who’s handy with electronics and from his investigation he felt as if it was an issue with the cluster itself, a new gauge cluster was bought and it’s the exact same story with the new cluster no speedometer illumination and no abs light. I’ve tried searching for wiring diagrams online to see what wires are responsible for speedometer illumination and abs light but haven’t been able to find anything clear that I can understand, don’t know what direction to go with the issue now,
Any help or advice is greatly welcomed!
Thanks in advance!
