Crafty_Fish Posted July 3, 2020 Report Share Posted July 3, 2020 (edited) Hey, Any info on this would be great! I've got a 2000 1.4 Lupo that when the dipped beams are switched on the rear fog comes on even with the fogs switch in the off position. I checked the fuses by the steering wheel and all were fine, has anyone else experienced this or know where else I should look? Thanks for any advice in advance!

mk2 Posted July 4, 2020 Report Share Posted July 4, 2020 I'm trying to remember how it's wired. I think the rear fog is powered from the headlight circuit via the main headlight switch, through the dip switch on the steering column, and lastly through the fog light switch that you pull out. So if high beam and dipped beam headlights work ok, the steering column selector is fine, as is the headlight/side light switch (main switch). Which points to the the main lights switch, fog light selector. It's a really unusual fault. Have you had a tracker fitted? They usually bung them in behind the light switch, connected to the always powered circuit. And make a right botch job of the wiring. To remove the light switch, instead of pulling the selector out, like you do to select rear fogs on, you push the switch in firmly to mid position. Then while keeping in mid position, wiggle and pull it straight out. The selector should stay pushed in. The whole switch assembly should come straight out revealing a ton of wiring. Press the retaining clip on the wire connector and disconnect the switch. Then you can swap over the switch or test it. And inspect the wiring leading into the connector. My guess is wiring just behind the connector (a tracker fitted) or the probably the switch itself. Let us know what you find. oh, and welcome to club lupo 1 Quote Link to comment Share on other sites More sharing options...
Crafty_Fish Posted July 4, 2020 Author Report Share Posted July 4, 2020 Hi, Thanks for the incredible answer! No tracker fitted, it was a run around that sat for over a year before I got it. I ran out first thing this morning and pulled the switch unit out, the process was exactly as you described. All the cables looked good and there wasn't any flickering when they were wiggled, what I did notice was the fog light would flicker on and off when the switch itself was wiggled. Going to order a replacement for the sake of £10. The answer and the welcome are greatly appreciated! Quote Link to comment Share on other sites More sharing options...
