Turn Signal/ Hazard Issues...

[conor]

Okay, so I've read through this thread (and Smokey Eddy's as well as all others I could find), which is somewhat similar:http://www.vwdiesel.net/forum/index.php?topic=18568.0...but it doesn't seem to cover exactly whats going on with mine.

So when I put on the hazards (with ignition off or on) all bulbs work. I had previously replaced all of the bulbs and checked the connections.

But when I put either turn signal on, the green light in the dash goes on but does not blink. The turn signal lights don't go on at all. I went through the Bentley suggested tests, and it seems like the switch is fine (same constant green light on dash when pins are jumped on switch connector) as well as the relay (though I'm not positive how to test the relay individually). I went through and the grounds and connections seem good. It did appear that the positive feed from ignition (pin 15?) was getting power toward the relay...

Anyone have any ideas/suggestions?

Oh, and I checked and saw that the front passenger side does not go on with headlights or parking lights. Driver's side light works for both, and both sides work with hazards...

edit: checked fuses, all appear to be good

I'm not 100% clear from your post, but turn signals are not suppose to work when the key is out.

Both the hazard and turns use the same relay for blinking so if one is working then it's not a problem with the relay

You and I have the same problem. How is your issue different from mine?
I think if the switch in the steering wheel is working then perhaps there is power getting into the circuit from somewhere it's not supposed to (like the headlights or something to that effect)

Also, would it be possible for you to scan or take a picture of the bently tests? I need to test my switch as well but alas, i have not a bentley

I was testing turn signals with ignition on.

If I understand the manual correctly (which I don't have in front of me right now) you're putting power to the relay through 2 different sources for hazards vs. turn signals. I think (and again, I should have the manual in front of me before saying this) it was power from pin 15 from ignition that is the power source for the turn signals...

Maybe its not any different from yours, just didn't want to hijack your thread if it was...yeah, sorry, i guess i didn't read through yours carefully enough, they are very similar issues.

I'll see what I can figure out with the page scans. I don't have a scanner but might be able to get some readable digital pics.

So...if my understanding of the relay is correct, there are 3 pins: 49, 49a, and 30. 30 is ground. 49 is your lead from either ignition or your hazard switch. 49a is your flash output to both the switch (for hazards) and the lights as well as the dash (for turn signals) and the lights.
.....so, if i'm getting any type of signal at the dash, I must be getting 12v to pin 49 when i hit the switch, right? And as you guys mentioned above the relay must work if the hazards work. So I'm guessing the problem must be elsewhere...

(hey thanks for shooting me those pics of the bentley - if my issue isn't the switch it will appear we're chasing the same tail)

It just might be a bad connection at the relay, the hazzards pull more pwer (4 Bulbs) than the turn (2 Bulbs).
Rears are 1156. fronts are 1157, does having your running lights on change anything?

[Smokey Eddy]

not for me no.

[Smokey Eddy]

I'd like to add that one of the turn signals up front has BOTH filaments going at all times...

[Smokey Eddy]

Conor did you figure it out?
im still stumped with mine =(
and its getting very agrivating driving with no turn signals.

[somolovitch3]

If both elements are lighting up, there is a bad ground INSIDE the socket. I have had to cut one open to repair the ground lead between the bulb base and the wire. Check to see if there is any corrosion at the relay, both the base, and on the relay contacts themselfs.

Ok so Conor isn't posting anymore so im hijacking this thread.

Does anyone know a source for the pig tails?
the shop in town can't get just the pig tails so with the lens cover they are $25 a side.

You could try to check the contacts on your switch. I've never had any trouble on the turn signal side of mine but on the wiper side I had some weird things going on and it took me a little while to pin it down. What I eventually discovered was that over time the contacts on the switch had glazed over and the added resistance was giving trouble. I could use the wipers OR the washers independently but they both wouldn't run at the same time. The fix was easy enough though, I just popped the steering column cover and stuck a fingernail file up in there and filed the contacts a bit and it straightened everything out.

[Smokey Eddy]

yeah i replaced the whole switch.
didn't fix anything to the tune of 36$

[Rabbit79]

Don't you just love it when you spend that kind of money on a part and it doesn't fix a thing? 

[Smokey Eddy]

It's just awesome. At least i know that wont break now though. SOME peace of mind.
next im going to try the relay.
Then if that doesn't work i might just have wire my own flasher relay and wiring.
stupid car...
