Headlights wont turn off

Just as the title says, the headlights on my 2006 F250 Lariat wont turn off. They are on when the switch is at automatic, off, (P), and on. Brights can toggle back and forth like they should and so can the fog lights.

Any ideas?

be an easy fix

Have you washed your engine bay recently?
After I washed mine, I believe water got in the wiring and was causing it to act weird...
they wouldnt turn off also. Then the water dried.

Last week sometime I did wash the bay and last night it rained. I guess I will hold off on buying a switch for a couple days to see if it dries.

Stock bulbs and everything?

LOL
Im running the exact same thing


This happened to me in the summertime. They never really went back to normal.
What I mean is, after I washed the ballasts, I think they went bad.

The headlights wouldnt turn off for days unless I pulled the fuse.
Then wouldn't turn on, NOW, the low beams dont work AT ALL, but when I turn the high beams on, my lows are actually working. which is how i've been driving recently LOL

I have DDM HID's and I firmly KNOW that they are a great kit and I messed them up.
(I have 4 fogs running ddm also and they work great

I was thinking the headlight solenoid was stuck, given the switch was not seeming to work, except for fog lights.

additional information for anyone who knows about HID light kits.. With the headlight switch turned off and the HID headlights on, I disconnected the OEM light harness from the HID light Harness. This breaks any connection from the HID headlights to the headlight switch on the dash. The lights remained on.

With both lights still being on while disconnected from OEM harness tells me that it is not going to be a bulb issue, ballast issue, or relay issue as the probability of both left and right parts failing simultainiously is extremely unlikely.

This leads me to point the finger at the control module in the light kit. I am taking the truck up to our HID light guru this evening when i get off to have him confirm my suspicion. I will let you know the outcome!

Please update this thread if you find anything out. I am still having issues with mine and could use some help.

By the control module... what are you reffering to?
