Re: Running lights
I just posted in another thread, but felt it was appropriate to repeat it here also. I had the marker lights added to my H3 and went through hell trying to get the wind noise and vibration stopped. Finally, after the GM fix kit did not work, they drilled another set of 6 holes and moved the lights back as far as they would go (AGAINST THE XM ANTENNA)! THAT FIXED IT!!! I have had it up to the rev limiter (99mph) on numerous occasions, in various directions and wind conditions, in clean air and behind 18 wheelers, and not a sound or irregularity. So I guess the answer is to make sure the lights are back against the XM antenna and you should be good to go! If they are not back that far, the wind coming off the windshield is subject to catching the leading edge of the light bar and causing the noise and vibration. The difference I'm referring to is only 3/8 inch, but that little bit seems to allow the wind to pass over the light bar without catching the leading edge of it. Have a great H3 day!
