Hello first time posting and glad to be here.
I have been trying to hunt for the source for a month now and I dont intend to give up. I removed the rear seats and trunk cover but still inconclusive. I listened in the trunk while someone driving as well.
However, today I think I made a small progress. I notice that the rattle goes away when it rains. So today and no rain, I poured small amount of water at the rear windshield to simulate rain and the rattles went away. What can it be? I believe the rear window on this thing is not original too but I dont see any damaged on rubber seals unless its under the window? or can it be something along thebtrunk where the water flows out
?
