[Judas Iscariot]

low - 13.7 -- 13.7 - 13.7
hi -- 13.4 -- 13.3 -- .47

No problem. Try pulling just the passenger bulb and then turning on the headlights to see what the driver's side bulb does in the three states with the other removed.

[Judas Iscariot]

gonna do that on my lunch break...

here is the picture

[Judas Iscariot]

oh and the white wire is actually grey

[CTScott]

Hmmmmmm. I am still reallllly thinking that the H-LP/AMT Relay might be the culprit.

With the bulbs both in, the charts should look like the following:

Driver Side
----- Grey Green Brown
off - 12 -- 12 -- 12
low 12 -- 12 -- .4
hi -- 12 -- .7 -- 12

Pass Side

----- Black Blue Brown
off - 12 -- 12 -- 12
low - 12 -- .4 - 12
hi -- 12 -- 12 -- .7


On yours, the low beam power is not being properly switched. On a working car, if you pull the relay, the high beams will work, but the low beams will not turn on at all (which is basically what you are seeing).

One last thing to try before replacing the relay is to unplug the DRL module's connector.

I disconnected the drl box and nothing. If Toyota is open tomorrow I will go get a relay. Or auto zOne. Some place like that hopefully has it

[CTScott]

If you can find a way to jump the two large blade slots together, while the headlights are on, and on low beam, you can do a final check to make sure that that relay is truly bad (since it is a $30+ relay).

Wow. Sparks! Lol I'm ok. But the headlight stalk was in off position and when I connected the two the lights came on. That was suprising! But it didn't fix it. Every time I think it will work It doesnt. Oh well. What's next?

I meant to say ONLY connect the jumper with the headlight stalk on and in low beams. In that state, did the lights come on?

[Judas Iscariot]

Another thing. I went put and pulled the relay. And the high beams do still come on, but the driver side lamp is still turning on both filaments. And they are still dim, really dim.

[Judas Iscariot]

ugly....

No way! There seems to be way too much of that going around lately.

I have exactly the same problem with my car. One minute everything was fine, next minute the low beams no longer work.

May I ask how you fixed it? I don't understand what 'total it' means in your summing up sentence "Thanks CT.... all i had to do was total it" :/ :)

Cheers.

Unfortunately, by "total it" he means that he got in an accident and completely wrecked the car.

With your, have you checked the bulbs? The most common reason for no low beams is that both bulbs have burned out their low beam filament.

Oh wow, sorry to hear it. I am, however, hoping to have a better resolution. :o

I was thinking that the fact they both stopped working at the same time was too much of a coincidence, but the cost of new bulbs makes the most sense to test first.

Cheers.
