Hello all,
Electrical gremlin on my 2006 Grande Punto Active 1.2 that has me stumped.
When I turn on the rear fog light, the light comes on momentarily and then goes off. The bulb failure warning light then appears on the dashboard.
I understand that this light does not have a dedicated fuse but is served by the BCM. All other lights on the car work fine. However I'm unsure whether there is a dedicated relay (for example in the switch module) and how I would go about testing the system?
To date I have checked the following:
(1) Battery terminals clean and tight. Battery is fairly new and voltage is good (12.2 volts when off, over 14 volts when running)
(2) Earth mounts in the engine bay have been cleaned and greased (2 under ABS modulator, one on chassis leg, gearbox earth strap and ECU earth wire on rocker cover - shout out to Andy Monty for some excellent guides)
(3) Fog light wiring checked - no visible breaks (though previous repair is evident as both wires have been soldered and shrink wrapped; is it possible to get these the wrong way around?)
(4) Contacts cleaned and Bulb changed - same result
(5) Fusebox checked for water ingress (including underneath) - dry as a bone. Bottom half is wrapped in perforated cling film for protection and lid is closed tight.
(6) ABS modulator checked - also dry
(7) Fixed broken wire in the boot concertina hose. I don't think this is related to the fog light but thought I would mention for completeness.
I've read a number of threads related to rear fog lights on this site. They either allude to a non-working light or one that stays on. I've not encountered one that momentarily works like mine.
Thank you in advance for any assistance.
