I'll preface this by saying the fog lights have not worked since I bought my D2 over 2 years ago. I've been trying to address a list of small issues on the Disco such as this, rear wiper and seat heaters over the coming months. I replaced the bulbs today as something to simply check off the list. Old bulbs looked ok but put new ones in anyway. I'd read possible corrosion issues on the connector can cause the lights to not function however things looked in good shape. Still no luck with the lamps. I still have got no power to the fog lamp switch or atleast the green light isn't coming on. No other electrical issues to speak of. What are some potential culprits here?
