Are you having problems with the head lights going out while driving at night? I have a 2007 Chevy Trailblazer LT and just got it out of the shop for the second time because of this problem. The first time this happen is when the vehicle just went out of warrenty (3) years old, the dealer installed a new control board after having the trailblazer for three days trying to find the problem, the $280.00 board was replace free. How the one that was replace only lasted 6 months and they have had it for two days and can not find the problem. While the vehicle was in the shop i googled "trailblazer lowbeam problems" and WOW, the problems that people are having, i printed out 6 pages of complaints that everyone is having, the same issues i have
This has been an issues that started back as far as the 2004 models and i just found this out and GM has no recall. The problem from what i have read is coming from relay #45 and #46....... BEWARE THIS IS DANGEROUS.....This past Saturday night approx 9pm heading home from Wal-Mart with no head lights, i am glad we bought TP while we were there because i had to set on a roll on the way home.
