So I walked out to my truck today and saw water coming out the passenger side door from the bottom and was and out the door and found that that whole side was flooded and water is coming from the floor heater vent I had to cut out the carpet and spend 2hr cleaning water from the truck any idea where it's getting in from the top

 

Been running your AC much? Could be a clogged evaporator drain. It's on the passenger side firewall made of rubber. If your weather is anything like it is here, your not getting much rain.

 

Don't have ac I use the truck for rally so i never bothered to put the ac in it for the added weigh and drags motor down I have a 2.5 so every bit helps and it was flooded after the bad we had here in fl all my dad could do was laugh his *** off then went back in the house it look like the was a water fall in my door
