I bought the car used and noticed the high beams weren't working, and since the highbeams and drl's (canadian car) are the same bulb they were not working either. I did some research on some nissan forums and decided to look at the module for some cracked solder points and sure enough there were about 6 cracks. I soldered over them and plugged it back in and worked like a charm! Search about it on some forums and there are tutorials showing how to take it apart, I broke the casing on mine but it wasnt that big of a deal to me. Cost a total of $30 for the soldering iron and solder and about 30 minutes of my time.
