I have a humming vibration coming from the passenger side windshield pillar at freeway speeds. does anyone know how to eliminate the vibration? seems to be secure whenever i inspect it but i can't find any other possible causes?

Have you had the windshield replaced as mine does that since replacement. I have tried to locate vibration but cannot find it. The fitters have obviously bent the trim somewhere causing the vibration.

 

If you have the roof lights it could be a good place to look. That's where my "Vibration noise at speed" is. Just can't seem to eliminate all of it yet.

 

I had it also, It turned out to be a plastic insert above the door that fits into the roof rack channel system, A dab of silicon fixed it,

 

I looked at mine last night and that plastic insert is cracked. I can't seem to find that part or an exploded view anywhere online.

 

went and looked the plastic moulding where it meets the roof trim. peeled it back a bit and found a broken tab attached to the mounting screw for the trim. removed the tab and sound is gone.... should get new trim pieces but thats another project
