I think I have found the problem. I pulled the trim panel today. I could not find any sign of leakage above the seat belt retractor. Then I pulled the retractor. Under it in the body panel was a large chunk of foam, and it was wet. The foam would rub against the seat belt webbing in the retractor, transfering the water from the foam to the seat belt. Looking under the cab, I found that there were holes in the body panels that were covered with a small square of rubber (looked similar to a tire patch) that were glued in place - and the one that was right where the foam was was loose. It looked like it was allowing road spray to get into the body panel, soaking the foam and then transfering the water to the seat belt. I re-sealed it with some silicone window sealant (and also a few others that I found were loose). I'll post again after the next rain to let you know how it worked.
