Hey all! I just got my vehicross and love it! There is this REALLY annoying buzzing sound which seems to be coming from the passenger side door. I tried messing with the locks and windows but can't seem to stop it. It happens sporatically but mainly when I go 20mph or more. Does anyone have any ideas on how I can troubleshoot this problem? I fixed a nasty rattle where the spare tire is but can't seem to figure this one out. Thanks a lot in advance!
