Hello, my name is ***** ***** I am a professional here at Just Answer. I have noticed that your question was not getting a response and thought I would see if you still need help with this.I apologize for the delay and I hope I can still assist you with this here.

Your back lighting get its power from the headlamp switch to the instrument panel dimming module through the fuse #24 (7.5 AMP) and then out to the lights. Start first with checking the fuse 24 to to be sure its not blown. See the wiring diagram in the link below for reference in checking the circuit.

Hello Ron, thank you for responding. I checked the fuse and it checked out good so i checked the continuity to the lights on the A/C, the lights are grounded, but when I turn on the head lights the wires are not getting power.

Okay the next step would be to check power in and out of the dimming module shown in the diagram.
