Chrysler Pacifica Forum : “Wet carpet on the passenger side. Any idea what could be leaking?”

Certainly sounds like the door seals are leaking.  You don't have a sunroof, do you?  Sometimes those get clogged and leak into the interior.  You may need to call someone like Rain Doctor and have it leak-proofed.

I am having the same problem I've had it back to the dealer 4 times and they still have not fixed it's driving me crazy because now it smells like mold. and I had my door seal replaced and it was not that and some black box under dash resealed. It rained today and again I have a puddle on the floor. I'm going to get out the hose and start from the bottom and work my way up to try to figure it out. why the dealer couldn't I don't know. I will post back if I figure it out just to help anyone else cause this is driving me crazy.    

Hi, since no one posted back, I will let you know that I had a similar problem in my used 2004 Pacifica at about 61,000 miles the passenger side floor was wet. I took it in and the service dept. found that on of the plastic drain tubes from the A/C that runs under the floor on the passenger side had become brittle over time and started cracking. This allowed condensation from the A/C to back up into the car and appeared as a leak on the floor. They had to replace the drain tube to stop the leak.
