Welcome to the forum firechick1435. :wave:
Sorry it is under these circumstances.
First, Do you have aftermarket light bulbs in your Nitro (HID)?
If not, Then there could be many different causes. It could be an issue with any one or more, of the following, as they all communicate with each other to illuminate the headlights.
The TIPM (Totally Integrated Power Module [fancy fuse box]), the EMIC (Electro Mechanical Instrument Cluster), the SCM (Steering Control Module [Switch]), the LIN (Local Interface Network) or the CAN (Controller Area Network) data buses.
There could also be an overload happening on the headlight circuit.
Do you have any codes?
Do the running lights still work?
The Nitro has a built in safety feature that will automatically turn off the headlights when they draw too much power. On first detection of too much draw, the system will cut the power, and they will go off temporally.
This will repeat a couple of times, then the TIPM will shut off all power to them, to prevent overloading the wires, and causing a possible fire. This is by design.
Before you mess too much with the TIPM read this
thread (
Read my posts carefully! There are a couple of warnings you need to know!).
What you can do is;
Back trace the wires from the headlights to check for shorts.
Check the TIPM connections for corrosion/shorting.
If you don't find anything, then it is dealer time, as they have the diagnostic scan tool needed for further testing.
