I have a customer that I sold two HID kits to. One for the low beams and the other kit for the high beams. I installed them plug and play and the whole passenger side never would work (brights or low beams). Then I got him a relay and put it on the low beams and now the low beams have been working great. Then I got new bulbs because one of the bulbs blew from the malfunction so I put the new Hi-beam bulbs in and installed another relay for them. The customer then left my house with every bulb working great. He then called me an hour later when he went to show his friend that they were all working and the passenger side hi beam bulb doesn't work again. I realize that this truck has DRL's and I read on this forum on another post that it is as easy as pulling a fuse to disable them so I am going to disable this weekend but I didnt think that would be affecting the brights like that though. ANyone have any ideas? Thanks so much in advance.
