Hello all,
I have a 1987 Wolfsburg weekender Vanagon and have just discovered an issue with the headlights. They will turn on when the key is off or with auxiliary power, but once the van is started, they turn off. They will not stay on while running. Does anyone have any idea how I could get this fixed?
Thanks for your time and knowledge, I really appreciate they help. |

Do you lose anything else when the headlights go off? (Fan, wipers, etc.)
This could point to bad ignition switch or the related "load reduction relay".
Check it & report back... _________________ 86 White Wolfsburg Westy Weekender

I am sorry for getting back to you so late, I have been working and helping out around the house and this was the soonest I could get a look at it. I went through everything and all fans wipers and other lights work. The only thing that doesn't work is the driver's side blinker. It only turns on but it doesn't blink when on to signal a left turn. |

djkeev and MURRAYMW1 thank you both for your replies. Speaking to the grounds point I just finished cleaning them all up. To clarify, The headlights are fully functional and on when the key is in auxiliary power, they all work great, but once your turn the van on and it's idling, they turn off. |

Vanagon does not have an auxillary key position.
Off
On
Start
If On powers the headlights and all works well before you turn to start.....
Then once you turn to Start and the return spring pushes you back to On it doesn't work.
And your grounds are known good......
I suspect the ignition switch contacts are burned.

Please do keep in mind that I am 3,000 miles away (unless you're in DC) And guessing on needed repairs via keyboard.
The ignition switch is a known weak electrical link on older VW's.
No harm will come from replacing it and it may actually fix your ussue at hand.

Its a less than $7 part so I figure why not it will probably need to be replaced eventually like you said and at the very least it will be something we can rule out as not the problem. When I get it and put it in if it don't work I will continue to look for help. Regardless, thank you for your assistance I really appreciate it. |

I just got the part today and I tried it without taking the whole steering wheel apart like on of you said (thank you for that by the way it saved a TON of time) After all of that that wasn't the issue.
So to reiterate my problem in case others are just coming in, the headlights will not stay turned on when the van is running. When the key is off the headlights are off, when the key is turned on the headlights are on, after the key has turned to start and the van has started, the headlights turn off. Does anyone have any idea what is going on?
Thank you to all who have submitted comments and proposed solutions thus far I am very grateful to you for sharing your knowledge with me, and grateful for the assistance. |

check the relays for the lights & the grounds
$$ on ign. switch is not wasted as it will surely fail eventually - take it with you as a spare _________________ .... |

Thanks guys, I will have another look at the grounds and check relays. I was also thinking maybe wires go crossed because there is a new stereo in the van that is hooked through the ignition, could that be the problem? |

Do you have the same behavior with high and low beams?
With the engine running, are you able to flash your headlights?
What about the parking lights? Working as expected?
Any recent work on the van? The new stereo - before or after the issue appeared?
Do you know when the issue appeared, or could it have been like that, unnoticed, for a long time?
Has your van been upgraded with headlight relays? |

Not sure if this helps, or if I'm being too simple minded, or perhaps I'm not recalling this correctly, but: is that not the opposite of the normal behavior? iirc, my headlights won't go on when I've flipped the switch until I've started the engine.
To me that says it's a logic problem, like two leads are switched, or something like that.
Just sayin'. |
