I have a 2011 toyota sienna just out of warranty and the dealership wont do anything for me. Only the driver side low beam/DRL lamp is not working, everything else works fine and the van does not have fog lights. The bulb is good, all of the fuses in the box under the hood have been tested and are good. I put a multimeter on the pig tail and its not getting any power. Does anyone have a wiring diagram for the headlights. The next step backwards from the light is the relay integration circuit and I fear the dealership is the only place i'll be able to get one from. Anyone else have this problem or have a fix for it? I would be greatly appreciated.

Thanks in advance

I have the diagram for 1998 - 2009 sienna. Do you think that would work? Is your car US or Canada? I can email you a pic of it. I am on my mobile device and for some reason i can't upload pics from it to this site. What is your email?

My ford pickup did the same thing. Low beam on one side had no power. Turns out, for it, there are 3 fuses for the headlights. One under the hood for both lights, one under the dash for the left, and one for the right. Another fuse for high beam.

My dealer did not say he won't help me, he just jacks me around until I won't come back.

I have a 2011 Sienna. The H11 low-beam bulbs are burning every 2 weeks. It's the third time in 2 months I replace both bulbs. Anyone know what causes the bulb to burn? Any similar experience and solution would be appreciated.

Thanks

Toyota is not taking ANY responsibility for ANY of these defective headlights. I was T-boned by a 2011 Toyota Sienna WITHOUT headlights....and CHARGED WITH THE ACCIDENT! The owner's son was driving the vehicle and didn't know 'the trick' of how to turn them on...I was not only held responsible but my Honda was totaled and I was hurt badly. Am in the process of finding an attorney to prove my innocence. Insurance dropped me. This Sienna 'problem' has destroyed my life. I am disabled and cannot work. I need a miracle lawyer who will 'go the distance'...if any exists.

I don't have any answers for this very old thread either, but paying attention to what's written would help. Clearly the authors of posts #6 and #7 are having a DIFFERENT problem than the OP. Mryan2011 wrote that his driver side low beam/DRL bulb is not getting power. Is that identification even correct? I have a 2009 and its low beam bulbs are NOT used for DRL - high beam bulbs are used for that function. If the 2011s also use different bulbs for low beam and DRL, but neither of those functions work on the same side of the vehicle, I would suspect either a fuse or a bad ground connection.

Anyway, posters #6 and #7 complained of bulbs failing prematurely, which is a different topic and should have been posted to a new thread.

Hmmmm. Sienna Chat appears to be full of questions, but not a ton of answers.
In this case note all the posters that have a post count of 1. This is an old thread from a few years ago. I am guessing the original poster and some of the follow-on posters would have had their problem resolved by now and could have come back to post the resolution (to provide value to the community).

At times there are isolated instances where the best option is for an individual to take their car to Toyota or a qualified mechanic for diagnosis.
