Automatic Headlights not working

Hi!! I am a newbe to this forum, but not to Jeeps.
I just purchased a 2013 JK Unlimited Rubicon. It has every option that I know of.

When I turn the head lights to On, they work fine. When I set it to AUTO the lights turn off. I am trying this at night (when the head lights should be on).

So basically if it is dark out and I set the control to On, the head lights will turn on, but when I move it to AUTO the lights will turn off.

I have owned a Grand Cherokee, Liberty, and a Suburban and that setting always worked the same way.


Am I missing something here?

Thanks for your help! Jill

do they come on when your wipers are turned on?

Is the ambient light sensor unplugged, blocked, or broken?

The light sensor is in top of the dash, center of the windshield. Is it covered/blocked by anything?

I had the same issue with my 2013. You just turn the key off when you're done driving AND then turn the light switch to off. Make sure you go to "Personal Settings" on the menu and make sure you set it to 30 seconds on light settings. The best thing you can do is read the internet site on "personal setting" because the Jeep manual is hard to understand. Just punch in " how do you set your use personal preference " on a Jeep wrangler. The internet will answer all your questions.

That is not the feature they are referring to.

Nothing is blocking the sensor. Plus if something were blocking the sensor, wouldn't I be getting the reverse of what is happening? When set on Auto they never turn on.

Not sure about the wipers. I think I have that setup in the Settings that you go thru on the dash. I'll check that out tonight.

Thanks!

Ok, after more testing it appears that the sensor is just bad and not unplugged.

The lights do come on if I turn the wipers on. Headlight switch set to off when that happened. (Someone asked that)

I drove down our lane which is about 1/2 mile in the dark when the switch set to AUTO in the dark and they never turned on.

This morning my husband started my Jeep for me and the switch was set to Auto, The lights were on!!! Turned off Jeep and turned back on, no lights.

I will call dealer and make an appointment!

Thanks guys!

Jill

Good luck - I'm sure you'll find a bad sensor to be the issue.

Just got the Jeep back from the dealership. Great first time (with this Jeep) at the dealership!! They tested the sensor and found that it was bad. Replace the sensor!! They say it is fixed. We will find out when it is dark!

They also did the recall on the transmission cooler line. That was a shocker since I was on a waiting list and told it would be fall before I would get it. Sorry to the person next in line that has to wait another 2 weeks. : (
