The likelihood is the switch needs replacing, the contacts burnout on them after a while unless you use an aftermarket headlight loom, the other circuits you mention are associated but it’s the headlights which draw the load.
I would imagine, unless there is a short the fuse is not blown and it’s the switch itself as it is common. No Guts, No Glory. 🇬🇧🏴🏴🏴🇮🇪🇺🇸⛽️🛢️⚙️🧰💪 |

Hi,
Ok, so does that mean this unit does not have any relay or fuse? Thank you for the information. |

There is no relay on this switch I believe. The power runs direct from battery through this switch and burns the contacts out. I bought a boomslang red bison after market to use two waterproof relays. I didn’t think much to it as was so I modified it to suit my liking 😊.
Long and short if it’s not the main fuse above the tunnel, a dodgy connection or earth then it is more than likely the stalk switch. |

The main fuses are above the gearbox tunnel, as said. If I remember the brake light, indicators and blower motor are on one fuse, there’s fuses for the side lights, possibly each one, then main and dip, one for each side. I had a fault with a switch, but it was the dim dip and it had burnt contacts/ melted plastic.
I also had repeated problems with the new rear lights blowing fuses due to poor contacts, but this was solved by fitting led units. The wiring looms chaff through inside the chassis rails, causing all sorts of odd things, such as flashing brake lights and indicators coming on with the brakes. |

Hi Blue Blood, Thank you for the information! Please see the attached photo with the red circle. I opened it last month and noticed that the switch is loose and doesn't stay in place when I turn on the light. So I found a way to temporarily keep it in place. Hahahaha...Just using it for a while before it stops working completely. hahahaha Click image to enlarge Click image to enlarge |

The contacts look quite clean from that photo like they have barely any wearing on them, may sound silly are they making proper contact?
It may be worth getting the old multimeter and check the switch and also the wiring itself for continuity? Past that it’s got me stumped 🤔

Yes Blue Blood.
The contacts look fine, and I suspect it's just loose in that area. Haha... maybe I'll double-check all the wiring and see. |

Hi there
I've had this problem over the years with the light switch not lasting long and not being genuine, so i paid the extra to have a genuine one and so far so good. There is a difference in the switches and you can see this on page 58 in " My 110 Millie " 1996 Golf Blue 300Tdi 110 Pick up. Keeper. Clayton. |

Definitely agree with that. Genuine all the way for switches but also just add a slight modification in the way of a headlight loom containing a relay. It’ll protect those more expensive genuine switches too 😉.
They are dead simple to install and can be made up fairly easily if you didn’t want to buy one off the shelf. |

Or can get rid of the sealed beams (they are hard to come by anyhow) and replace with LED headlamps. They consume much less current so the switch will not melt down. 1988 90 Hard Top, 19J Diesel Turbo, Shire Blue - Restoration ongoing 2012 90 CSW, 2.2TDCI, Santorini Black |
