hello guys here is my story.
about a month ago i installed some cheap ebay hid kit for the headlights on my 08 maxima. the driver side went out so i went and ordred a ddm tuning kit. well heres my problem the parking light turns on but not the head light when i plugged the the headlight "whole assembly" to the passenger side it turns on. ive checked the fuses under the hood and they seem to be good. im lost any ideas.?

 

You gotta troubleshoot your electrical system. Switch it around and see if both works. If it doesn't try connecting it directly to the battery and see if it works or not. It can be a simple thing like a grounding issue or just a defective ballast of bulbs. Hope you still have warranty
