Good evening, the interior lights in my vehicle were working before and now it is not working due to the fact that I was trying to do some wire connection and I got a little sparks and then after that all the lights went out. I checked the small fuses, but I don't how to check the others. Do you know what could cause this problem? Thank you in advance.

Hello,

This sounds to me like you had a short to ground with the interior lighting circuit, which would have blown a fuse. In the diagrams down below I have included the wiring diagram for your vehicle's interior lighting circuits with the fuses and locations highlighted for you as well as the diagrams with locations and callouts for all the of your vehicle's fuse boxes. Here is a link for you to go to below as well:

Hello again,

If you were working on wires with your battery still hooked upped and you saw sparks coming from the wires you were working on and your interior lamps are not working any more, and by looking at the interior lighting wiring diagram, I don't see anything else that could be the cause of this. Please double check the fuses again and get back to us with what you find out.

Thanks,
Alex

Hello again,

That's the one I had highlighted for you in the diagrams I originally sent. Okay, so you obviously have an open in the courtesy lighting circuit. In the original diagrams the last two are the wiring diagram for your courtesy lighting circuit. In the diagrams down below I have included a guide for how to find an open in your vehicle's courtesy lighting circuit. Please go through this guide and find the open in the circuit. Please get back to us with what you find out.

Thanks,
Alex
