We are having the same issue with the puddle of water in the passenger floor.

I had this same problem with my Tracker. I repaired it with plumbers putty, never wet the carpet again. Look under the hood on the passenger side below the battery. you should see the end of a short rubber hose sticking out of the wall. This is where the A/C condensation drains out. The problem is that the opening through the wall is too large & the hose too short, water drips along the underside of this hose back into the passenger compartment. Use plumbers putty to completely seal around the opening in the wall and around the hose. Be careful not to block the hose. This should fix the problem.

Is ANY water dripping from drain hose when A/C is on? IF not , then maybe drain hose not hooked up properly. Compressed air blown back through it from under truck?

It could be something on the motor side by the firewall is not sealed right I would take a tube of silicone and go around the hoses,wires and anything else in that area and seal them so water can get around them.

Passenger side is wet when it rains...
