Turn signals not working, Relay OK, Fuses not blown 1994 Golf Mk3 1.9SDI

[radiant dirge]

Does the fuse have any power being sent to it at all?

If theres no power being sent than thats one problem, people often check for fuse blowout without checking for nothing going to it at all

This is a take out a shit ton of wires and run a multimeter for a while kind of deal

[unborn stream]

Not sure gotta check that sometime next week

[unborn stream]

Fuckkk

How do I test if its the switch?

[radiant dirge]

I would see how much power is going to the bulb and go backwards from there

[unborn stream]

Next thing is planning is to put WD40 on the switch internals to make sure its not corroded

[radiant dirge]

It sounds like theres a fluctuation there

[unborn stream]

Could you please please please explain how Im not familiar with the Multimeters even though I got two

[radiant dirge]

Theres some amount of voltage in the system that allows it to start but it all goes away so power could be delivered too slowly

[unborn stream]

Like what do I do, where do I begin all that

[unborn stream]

Mhm I see

[unborn stream]

Could corrosion/dust/etc cause this? Or no?

Maybe dirty contacts

[radiant dirge]

Maybe corrosion on the wiring, contact points, or any conductor that would cause it to lose charge

[unborn stream]

Could I try spraying WD40 on the switch contacts, fuse contacts and relay contacts maybe?

[radiant dirge]

I dont think its too too likely but that being said, if something is enough to draw power like that you will certainly see it through a visual inspection

[radiant dirge]

To get them loose or what

Oh nevermind im stupid

I get pb and wd40 confused all the time

[unborn stream]

What should I try testing first in your opinion?

[unborn stream]

Nah its all good

[radiant dirge]

Well first have an understanding of how the power flow for this particular system travels. You can either start at the end point, the start point, or somewhere in between. Just use process of elimination to work yourself backward or forward to zero into a possible trouble area

[unborn stream]

Oh and just to see if the contacts might be the problem

[unborn stream]

What would be those points

This is ig the wiring for the turn signals

[radiant dirge]

And the hazards work?

If the hazards work normally i would start there and work my way up to the bulb itself

[unborn stream]

Ye

[radiant dirge]

Nothing a diagram and some youtube tutorials for location cant fix

[unborn stream]

Hazards work fine, all bulbs light up

And work normally

[radiant dirge]

Start at the hazard switch then

Because if power goes there and it works normally it and everything before it is clearly ok

[unborn stream]

Okk

The hazard switch and turn signals should have separate wires

I think, but they work from the same relay

[radiant dirge]

I believe so yes

Check the system from there and up and let us know how it goes

[unborn stream]

So hazard switch from top to bottom testing

[unborn stream]

Alright

[unborn stream]

@radiant dirge Fixed

Sprayed some contact spray at the side into the turn signal switch contacts and it started working like a charm

Ended up being dirty and/or dusty contacts, I would have tried cleaning it more but

For that I need to take off the steering wheel and last time I did that to another Golf I ended up not fitting the steering wheel back properly so it was crooked

[worn ferry]

Nice!
