Look in the passanger side at the firewall right under the receiver drier you will see just a pipe probably filled up with dry leaves

I drive a 94 mustang and all of a sudden it started leaking under the driver side dash into the floor board and leaking under the car on the passenger side onto the ground and ideas????


AC removes water while cooling at the same time. The drain is partially plugged in the drain pan that is under the evaporator coil. Now it overflows inside your car and onto the ground at the same time.

Air conditioner causing water inside front and rear of vehicle


on your airconditioning unit on the fire wall under the hood...you have a drain hose to let water out ..if that is plugged it will run inside the vehicle...but what causes this usually is low freon...134A..its the gas inside the lines....when ac is running..if its low it will freeze up in the AC condensors in the dash...turn white which is frost..if it gets frosty then it will melt thus causing water which in turn runs into the inside of the vehicle..that is if the drain tube hose is pluged...suggestions >> get under car and look for a tube..rubber...insert a wire or something up there to see if dirt comes out...do this without car running...someplace on right side glove compartment area under car has to be a tube..tube goes up and down vertically probably two feet long but you will only see the tip of the hose,,maybe a couple inches,,,only way to find it is get under and behind right front wheel and look upward .find it and make sure it isn't kinked or anything as such,,plugged...then try again...the cause is low freon 134A...stop and think,,,on a hot day when AC is running,,,you drive a bit and then park...you come back out and there is water behind the right front wheel ,,,if that is happening..you have an open tube...but if water still inside during the puddling outside....then a loose or cracked housing which contains the unit...shouldn't be too hard to fix

1999 isuzu amigo water in passenger and driver floorboard no antifreeze smell at all.


this sounds like a build up of condensation (water) possibly in your ac/heat ducting or possibly in the plastic casings under the dash that house some of the heating and cooling components. cold ac components close to warm or hot heating components will lead to water build up this is why there should be a drain tube for the plastic housing under the dash board that leads to the outside of the vehicle. this drain tube may be clogged or may be disconnected and not draining to the outside but instead its allowing the water to fall into the area under your dash board. FYI you can sometimes see these drain tubes drip water on cars that use their air conditioner a lot, it looks like the car is leaking water from the bottom but it's just the water draining away from cool air conditioner lines on a hot day and draining properly to the outside of the car and not on the floor inside.

Condensation is leaking inside instead of under the vehicle.


Look for the drain under the hood ,directly below where the ac lines go into the firewall,clear it out with air pressure.When it is unstopped,the drain will allow a bunch of water to come out quickly,and alot of it.

My 2004 isuzu Rodeo Ac drain keeps cloging and I can here water in the duct work on the passenger side. How to I find the drian and how do I un clog it?


You can locate the small hose sticking out from the engine bay, or looking up from under the vehicle. Chances are there are leaves or excess dirt clogging up the hose. The easiest way to locate is to look under the dash on both sides and find the largest box in the duct, it is normally the lowest also. The hose will be on the opposite side of the firewall in the engine bay. you can buy a/c coil cleaners at your local home depot or lowes and try to spray that inside and flush with water. The best way is to remove the box and clean the coil enitrely with the coil cleaner, and flush. It might get a little messy, but if you can do it yourself you will save a whole bunch of money.

Water leaks on passenger floor when air is on


AC drain hose stopped up somewhere, probably under the vehicle. Sorry I don't know where it comes out of the firewall or fender.

2004 Mitsubishi Endeavor ac condensation drain is clogged.


It should be under your hood, on the firewall. Should be a short black hose there somewhere.

Water leak on mitsubishi galant 1999


the probable cause is the drain for the ac coil is stopped up for an a/c leak inside.
if it smells like anti-freeze, the heater coil is leaking and may need to be replaced.
