Question about 2001 Mitsubishi Montero

3 Answers

Water leaks into the floor on the front passenger side under the floor mat. It is not antifreeze. Only when it rains hard. Seems like it is coming in from the front side, toward the door in the corner.

Based on what you are saying I would bet you have a body seam leaking. Remove as many things as you can to get a look at the rf corner inside the car. Close the doors and have someone spray the car down with a hose and see whats leaking if possible. If the hose dosen't produce any results try a high pressure car wash. One other thing you may want to check is the heater box drain tube(this should be a short rubber hose coming out the bottom of the heater box, its what leaves the puddle of water on the ground when your a/c is on) If this is restricted or plugged water will back up in your heater bax and drain onto your floor. This will mostly only happen when using the a/c. Good luck!

Why doi hear water in the dash on a 2004 chevy impala


That's the antifreeze entering and exiting the heater core, which is located behind the glove box of the dashboard. If there is sweet smell or antifreeze on the inside floor on the passenger side, you have a leak in the heater core.

2004 nissan sentra rain leak passenger side


Someone in the car watching for leak, someone outside the car with a hose.. Gently apply water to the door area and person inside looks for the leak... Another possibilty. If the water is comning from under the car it can be a rusted place or a body separaion.. harder to find. It can be comning in from around the windheild seal and running down the interior firewall. This is how a shop would find the leak.. but they would charge you for it..

I would say you have either a bad seal on the windshield or the seal on the passenger door opening.

are you sure it is water, smell it to ensure it is not antifreeze (smells sickly sweet), if it is antifreeze possibly heater core leak, otherwise check for plugged evaporator drip tube (with a/c of course), could also be leaking body panel (cracked chalking etc). hope this helps

Water leak on fwd and back passenger side after every rain storm


pull your carpet up near the leak area and look for muddy body seams. it is possible one of the factory body seams are leaking- possibly in the cowl(under wipers) area, especially if it leaks when the car is sitting. there will be dirt/mud around the seams that are leaking. also you can check door seals by running the car on HIGH DEFROST with all doors and windows closed. spray around with a 50/50 soapy water solution. obviously bubbles will form around your leak.

Wet under driver's side floor mat


Is there a sweet smell inside the car?Heater core leak I beleive would be on passenger side floor.Antifreeze will be sweet to the nose.Are you getting any white smoke out the tailpipe? would likely be head gasket leak.Put a piece of cardboard under the car near the radiator and under the motor to see where its leaking from .One thing Ive learned over the years is that its going somewhere.On the ground? Or out the tailpipe.
As for the floor board leak the 98 s were prone to have the defrost area in front of windshield collect water from being plugged up .Mine was passenger floorboard.Daughter resealed small oval vent (that defrosts /heats hood?) LOL .Its on pass. side under hood on cowl .I think this will take care of my problem but you may need to investigate under the dash/defrost area and drill and then install a drain line to bottom of defroster.Exit drain line to O/Side of car...lol .Also was it raining ? was car outside in rain .if so it could be this issue.Sorry so long ,hope you can make heads or tails of this.

Water leaking into KH laser Hatchback


It could be coming in through the rear door as the rubber might not be sealing properly the easiest way to find the leak is to remove your seats and carpet sit inside get someone to squirt the car round the doors and windscreen air vents.

Wet passenger side


I believe the problem is a leak in your heater core. The water would run down the inside of the firewall or near it thus running under the mat.
