why is the passenger side floor always flooded everytime it rains. on 2008 Dodge Nitro R/T

floor always wet when it rains could it be the ac drain plug backing up

Asked by for the 2008 Dodge Nitro R/T
It is best to look for water leaks when everything is dry. First is the door seal or door, damaged in anyway? I have seen the seat belt having damaged the door seal on many vehicles. Do the doors close flush with body? Ensure the door seal makes good and uniform contact with the door (particularly important if the vehicle has been involved in an accident. You may need to pull back carpets pull back the carpets and sit inside the car (you may need a flashlight) and get a friend with a garden hose to spray water around the door jams to determine if the water is entering the doorway. Then spray water around the windscreen moving around the circumference of the windscreen. Look around the windscreen area and look up from the floor mat area (as best you can) to determine if water is leaking in around the windscreen seal. Is there any rust around the windscreen area or body work? If you have a sun roof there is a drain tube at each corner of the roof to channel away water. A blocked drain may cause water to fall from the sunroof area Water can also come up through the floor pan as you drive through water on the road, if any rubber bung or “seam sealer” has been disturbed or is missing. Remove any debris present in the panel below the windscreen, and ensure any drains for the cowl area there are free and not clogged up or restricted.

do you have the passenger window shut when it rains? lol sorry i couldn't resist asking. but it could possibly be ac drain plug if you run ac when it is raining. or it could be as simple as passenger door jam seal. check to see if it isn't damaged. if it is not, then check your ac drain by simply turning on ac and give it a lil time maybe 10-20 minutes running, then exit your vehicle to check (on passenger side of course), if it is draining underneath vehicle. also drain should be visible by lifting hood and standing on pass. side. it is close to firewall. email or call for further assistance. 336-712-5285 sam...
