Ran into a situation recently... I have had no problems with my 2006 big horn. I updated to the Brite box from Geno's that allows the fog lights to be used with the highbeams. While driving one night. . With low beams and foglights on. MY driver light flickered then went out. Shortly after my passenger side went out. Then my high beams went out... I drove home with fog lights for 20 more miles. I was disappointed and automatically blamed the bright Box. I disconnected the Brite Box next day and I end up with High beams and funcioning fog lights. . No low beams. Called Genos and customer service was Great. He sent me a new Bright box and said that it may be faulty or it may be the computer on my truck! WHAT?... Any ways. sent back my Old box, installed the new Brite Box and ended up with the same problem. No low beams. Changed bulbs and checked all connections prior to contacting Geno's and everything seemed OK. I contacted the Manufacturer of the Brite Box and he told me that it's the computer. Just take it back to the dealer and they'll upgrade to the new computer that should solve the problem?? How come the day the brite box was installed the problem occured? Anyways. took it too the dealer today and they ran a diagnostic test on it for 100 bucks. they call me 2 hours later and say it's the totally integrated module/ Front control module and it the cost is $830 with labor!!!! WHAT? Any way short story. I pick up my truck and tell him that i'll set up a later appointment to scrape $800 dollars for a working set of low beams... Any ways the rest of the story ends up really Happy! I'm not gonna say how just in case certain people read this... . My brother... thanks for the help and the first class service and installation. . Your Dealership is 2nd to none! thank u for the help. . Enjoy the Pupu's, smoke meat and Heineken!!! u the man!!
