Welcome to the forums. Begin with the simple things first. No high or low beams? Do the front and rear parking lamps work?
Does the flash-to-pass work when pulling back on the turnsignal stalk? Does it have DRL (daytime running lamps) and do they work when running and in gear?
If you have no headlamps whatsoever, I have seen both headlamp bulbs blow at the same time. Check both bulbs for open filaments. Other than that, it may be a wiring, switch or module issue.
I have included some headlamp circuit information below. Do some preliminary diagnosis and let us know if we can further assist you. Best of luck to you.
The headlamp system includes the SCM (steering column module), the EMIC (electro-mechanical instrument cluster), the TIPM (totally integrated power module - underhood fuse/relay box), and the left (lighting) multi-function switch on the steering column.
The headlamp bulbs have a path to ground at all times through their connection to the engine compartment wire harness. The engine compartment harness has takeouts with eyelet terminals that are secured to the front end sheet metal within the engine compartment. The TIPM will store a Diagnostic Trouble Code (DTC) for any shorts or opens in the headlamp circuits.
The SCM monitors a hard wired multiplex input to determine the status of the left multi-function switch and whether the headlamp high or low beams are selected. The SCM then sends the appropriate electronic headlamp switch and headlamp beam select switch status messages to the EMIC over the LIN (local interface network) data bus. The EMIC then sends the appropriate electronic headlamp and headlamp beam request messages to the TIPM over the CAN (controller area network) data bus.
On Chrysler models, the TIPM responds to these messages by providing a pulse width modulated voltage output to the headlamp bulbs through high side drivers on the right and left low beam feed circuits to illuminate the headlamps, and controls the high and low beam shutter operation through high side drivers on the right and left high beam feed circuits.
On Dodge models, the TIPM responds to these messages by providing a pulse width modulated voltage output to the headlamps through high side drivers on the right and left low and high beam feed circuits to illuminate the selected headlamp filaments. The TIPM also sends the appropriate electronic messages to the EMIC to control the illumination of the high beam indicator. When the optical horn feature is selected, the low beams will shut OFF about 200 milliseconds after the high beams are activated.
The TIPM also remembers which beams (LOW or HIGH) were selected when the headlamps were last turned OFF, and energizes those beams again the next time the headlamps are turned ON. The TIPM provides a battery saver (load shedding) feature for the headlamps, which will turn these lamps OFF if they are left ON for more than about eight minutes with the ignition switch in the LOCK position. The SCM and the EMIC each provide a fail-safe feature for the headlamps, which will cause the TIPM to turn the low beam headlamps ON automatically if there is no input available from the left multi-function switch. The TIPM also provides a fail-safe feature for the headlamps that will turn the headlamps ON automatically whenever a loss of CAN bus communication is detected with the ignition switch in the ON position.
Each headlamp includes an integral adjustment screw (domestic markets) to be used for static aiming of the headlamps.
