For my wife's 2002 Honda Civic, it was the AC drainage hose that was clogged. Took forever, but finally located the hose - shot it with some compressed air and it drained out fine. To locate the hose, get yourself way under the car. Directly behind (front to back) the oil pan, about 8-12 inches at the firewall that separates the engine and passenger compartment, close to the exhaust - there is a small hose that comes out, bends to the right and then down. Remove, blow out with compressed air and reinstall. Problem should be fixed.

Was the air conditioning on? Usually water on the floor of the passenger side would mean the AirConditioners drainage hose was either clogged or became disconnected.

Your heater core is probably the culprit, they do this and some of them are a real bear to change out.

there may be a few things causing this, first make sure there no open holes in floor, then check trunk seal and make sure its not coming from trunk, next would be the back window,take a water hose and spray diffrent areas and check for leaks inside,could be also rubber around the back door or rust holes in wheel wells of rear wheels,

Water leak on the passanger side of a 1999 Jeep Cherokee Sport


The first place I would look is the floor board caps. Make sure one or more of them aren't pushed up, allowing water to enter the cabin. Also, because your defroster is probably on while it's raining, make sure the A/C drain plug isn't clogged. It's a small rubber fiting that sticks out from inside the firewall, behind the engine. Simply pull it out and clean it. When you pull it out, you might be surprised to see water coming out of the hole!

Just a couple things to check. I hope this helps! :)

Wet floor passanger side


Air conditioning drain stopped up with debris (leaves,pine straw,sticks). Small tube sticking out from firewall with rubber elbow pointing down behind engine, passenger side. If elbow missing air will cause water to back up into vehicle. Another possibility, if your coolant is low heater core leaking.

Wasn't no problem with untel i replace my water pump. as i finish the water pump job i turn the truck on and feel it up with antifreez and at same time i turn the heat on and smell of entifreez comes out...


You have an antifreeze leak. Probably in the heater core (a small radiator inside of the dashboard that heats the air as it passes through). When the engine is running do you see any steam around the engine? Or smell the sweet antifreeze smell around the engine? If not then it is probably the heater core instead of a hose or somewhere on the engine. Does this truck have the option to switch the heater to recirculate he air inside the cab instead of drawing in outside air? If it does then you can set it to recirculate the air inside and if it still has the smell then its definitely the heater core. Often with a leaking heater core the passenger side floor and firewall area will get wet, but not always.

(unless heater core is leaking but you didn't mention any overheat or coolant loss so likely that's not a problem)
