On my 98 ls400, when I switch my headlight to auto it is not working like it suppose to be, i tried it when it's dark/night and my headlight remains off. Anyone have an idea what could it be? Do this year have that feature?

 

If you have the "Auto" position on the stalk switch you will have the feature, the sensor is on the top of the dash close to the windscreen make sure it is not obstructed or covered over.

 

Widescreen??

 

Windshield, just at the bottom near the front end of the dash.

 

Okay I see these two circle one gray one black seem like the gray one can b pop open so I'm thinking that's the sensor? I checked nothing blocking either one

 

I finally pop out the sensor unplug it checked it and reinstall so waiting til night fall and I'll go try it out see if it did anything

 

So I have taken both sensor out unplug and plug back in and yet still not working, guess ill have to replace them. Anyone know what they are exactly call or where I can find some?

 

could be your switchh. you need to ohm out the sensors see if there bad before buying parts you dont need.

 

Sorry I'm a Brit!

 

Haven't resolve this issue yet, kind of forgot about it lol, but do anyone know where the switch is located at?

 

First thing I would do is check your fuse boxes. Could be something as simple as a blown fuse. I went through and found a few blown in mine not long ago. Things started working that I forgot that I had. If this isn't the case, do like SkulCracka said and break out the multi meter.

 

the switch is the stalk itself. you need to make sure the ground it's triggering is still working properly (easier said than done). you need a wiring diagram to show where the harness goes to and what color wires are what. like Taffy said, check the fuses first.

 

The fuses under the dash correct?

 

Did you check the light bulbs? lol

 

Bulb work fine, high beam work low beam work and parking light work
