Automatic headlights stay on during the day

[Rockcrawlin]

Hello,

I have a 2007 1500 and I noticed today on the way home from work that the headlights and dash lights were on. The light switch was set to the automatic setting and being 3:00 o'clock in the afternoon I would not have expected them to be on. I was able to turn them off with the knob but when I turn them back to automatic they stay on. Would it be the little sensor on the dash or something else. Anyone else have this problem?

Thanks for the help.

You do have daytime running lights. Could it just be those? And your interior instrument cluster lights are always on.

on my 05 there is a sensor on top of the dash a little black knob thing. and instermint cluster lights on auto only turn on when the sensor kicks in with dim light.

It's called day time running lights and they are always on, unless yo uturn the knob to shut them off.

I guess I should have clarified my question better. I know that my day time running lights are always on. Maybe its that konb thing not dimming my dashlights. is that common? I didn't check to see if it was just my day time running lights or if all of my lights were on. I guess i just figured since my dash lights were on so were the rest of my lights, I will check that tomorrow.

If your lights are se to manual your dash lights will always be one along with your driving lights .

The 900's use the headlights for DRL's not seperate DRL lamps like the 800's. So it's going to appear that your headlights are on, and they are as DRL's. I believe they are dimmer in DRL mode then when they actually turn on at full power.

Ok, that makes sense. What would cause the lights not to dim, other then the sensor on the dash board? Is there a relay or fuse that you are aware of?

Well the sensor is acting as such since it is sensing light, F-16s I work on use the same concept of sensors, but basically its the trigger for the system to turn things on and off or it may tell a system component the hey, its light outside or dark so turn this on and that off etc. Not sure about a relay but its possible if it sends signals to the brain to trigger a switch or diode or relay.

Well, I am almost afraid of posting this but I figured out what the problem was. The truck had a dashmat which had a hole for the sensor but apparently it was still restricting light from hitting it... It works fine without with the stupid dashmat.

Haha! Gotta love those easy fixes!

Cut the hole larger

F 16s awesome

dashmats are for dodges to cover up cracked dashes, and F16s are for badasses

You say that untill your the one working on it. Its def outdated but a workhorse.
