Has anyone experienced water under the pass. side rear seat? I replaced the front buckle which required taking apart my 96 interior in the rear. I found that the inner wheel well flange had rotted away and I could see daylight from inside the vehicle. Then I inspected from outside and saw the caulk coming out. The car was repaired on that side when it was a year old, but I think that, the part that has rotted was original. Has anyone else experienced this in their vehicle?
