Hey everyone. We had some good rain for a few hours this afternoon and I went to take the car to get dinner. It was still raining out, and I got in the car and the belt pulled out really easily. Of course, I then realized that the belt itself was soaked with water.
There is no problem on the passenger side. This happened once last summer, but it hasn't happened again till tonight. All I can think of is standing water in the body shell by the retractor that may cause rust someday until I fix this issue.
Where should I look first for a leak? Has anyone else had this happen to them? Any help would be great.

Windows are up all the way and the floor doesn't feel wet. Strange stuff. Anyone?
