How about you check it for $0 an hour with a garden hose. Run the water into the hood cowling and check under the dash with a flashlight. The light will reflect off any water leaks.

This is how I found a leak in my 2000 Blazer. There was a leak in the firewall/inner fender seam. The water was running down the seam under the carpet/padding and accumulating under the rear passenger floor.

A clogged AC drain will also cause rain water to puddle on the floor. The drain tube is on the firewall, low on the passenger side.

While we are adding possibilities, check out the drain for the area under the vents in front of the windscreen and drains on the sunroof

mcparadice, are you sure about the rain water? Don’t you think only precipiation from the A/C would drain into the floor?
