Default High beams not working?

I have a 2003 Jetta Wagon and the high beams have quit working, they only work when pulling the lever towards you (Flash maybe?). Fuses are all good but not getting voltage to the left and right high beam fuses. The only relay I can find is the one for the daytime running lights. Is there a relay for the headlamps on this model? Or could my problem be the switch located in the steering column?
Thanks in advance for help or suggestions.....

I had that same problem with my 03 wagon also.

What it turned out to be was one of the headlight bulbs.

Replace them and that will fix your problem.

Thanks, both bulbs seem to be working.......just not getting electricity to the bulbs when the high beams are switched to the on position.....was hoping it might be a relay but can't seem to find one.

One failed bulb will cause both not to work. Also, sometimes the filament will break and then flop around and make a connection, work again, fail again, etc. since they are the cheapest and easiest to rule out I would pull them out and visually inspect the filaments inside. If they check out I think you're probably looking at the high beam/turn signal stalk. I have read here of folks cleaning them and not needing to replace. Somebody will chime in about it. I do not believe our cars use relays in the headlight circuit.

Do you get power to the fuses when you pull back to flash?

Yes, there is power to the fuses when pulling back to flash the high beams.

Every thing points to the switch. The high beam bulbs work when you pull back on the lever, but not when you push forward, so the bulbs are both good. The circuit is good from the fuses to the bulbs. The circuit is good from coming out of the switch to the fuses so it must be losing power inside the switch.

Or am I missing something? I looked at the wiring diagram and I don't see how it would be possible for one bulb being out causing the other to not work.

I agree with you about the bulbs and I'm starting to think it is definitely in the switch. I was just hoping there was a relay so I didn't have to mess with the airbag on the steering wheel..I poured over all the wiring diagrams as well and just don't see anything else that it could be other than the switch........lot of posts here and elsewhere say its the bulbs but they work when you flash them and they work for low beams and the daytime running lights, I just don't see how that is the problem and if there is no voltage at the high beam fuses then it couldn't possibly be down stream from there.

Thanks for the help....

I'm telling you, it's the bulbs. Mine was the same way. I had to hold the high beam switch for them to work. Just try new bulbs

I agree about the switch and no a single head light bulb out has no affect on the other side unless you have botched wiring. They both have their own seperate earth and power.

Doesn't the flash to pass test show the bulbs as good?

With the evidence of people with WAY more experience on these cars than me, I am certainly questioning my thinking, so don't assume that I'm (now) saying that it can't be the bulbs, but I'm just throwing out the way I'm thinking of this, hoping to learn something new.
