I already checked the tail light but could not replicate the problem. but maybe my test was just not effective. I will take a look at the small side window trim as well.

Is there anywhere to check around the trunk lid? i feel like it might have seeped in from somewhere in that area. a few months ago i found a significant amount of water in the area i previously described, filling up the bottom with about a half an inch to an inch of water! and it seems there is some sort of drain plug on the bottom, when opened will release the water out of the vehicle. i found it odd there was a drain plug kinda thing there..as if something is expected to leak in that area?
