Make sure it is leaning just slightly to the rear and that the drain paths are clear. The water you are seeing is condensation from the cooling. You can also reduce this some by making sure you clean the filter every other day or weekly instead of monthly. The water should be draining out of the back of the AC on the outside.

    do i have to remove the unit from the sleeve to clean the drain paths?

  • James Young Jul 12, 2010

    That will depends on what kind of access you have to the rear of the unit. Sometimes you can clean the paths with a garden hose and a sprayer attachment and spraying the trash out of the unit. Sometimes you have to remove them from the sleeve. You have to kind of play that by ear and adjust to what you see when you start cleaning them. sometimes it helps to go ahead and remove the front plastic panel on the unit so you can clean the coils out while your doing it. This can be done easily with a Dog Flea Brush with all the very thin wires in it. The biggest thing is make sure it tilts just slightly to the rear.

Litters of water accumulating in the foot well of the rear passenger side seats which can soak your feet. There is dampness in front and other side. We have no idea of where this water is coming in from....


Depends on where the water is coming from. The 2 most often causes of water buildup is either the heater core is leaking or the AC condensate drain tube is blocked. If the heater core was leaking, you'd smell antifreeze or see steam coming from the vents while driving. The AC condensate drain tube lets condensation water to drip overboard from the housing. This tube is on the bottom of the AC case on the firewall side under the hood. Sometimes you need only pinch it to open it to drain out the water buildup..

AC vents not working


Does this vehicle have one AC unit in the front or two units one in the back and one in the front ?,if two units then the gas content is low as a two unit vehicle should hold at least 1.5 kgs if this drops over time due to leaks then only the front unit will work

Water coming out of front of unit, thru vents leaking on floor


Darlene, if this is a window or thru the wall unit, the leaking is usually caused by two things:

1. The drain pan under the unit has a drain hole (in the rear outside part of the unit) that is clogged.
2. The AC unit is not tilted down at the rear 1/4" to 1/2", so that water will drain to the outside drain hole.

Be prudent when you look for the drain hole in the drain pan. As the clog can blend in with the drain hole, making it difficult to see.

Hope this helped you troubleshoot and solve the problem.

AC not cooling during the day


Your AC cooling efficiency is low when he ambient temperature is high and naturally it cools well when the outside temperature drops.

Please remove the filter on the grill and try to clean it under the tap water and after removing all the dust fix it back to the unit. This would increase the cooling efficiency of the unit.

Your AC is also five years old. Please avoid frequent opening of doors or windows.

Ensure that the exhaust fan and the blower of your unit are functioning normal.

The technician might not have done a proper job in fixing the area where the refrigerant would have leaked out. Please check the refrigerant pressure to ensure that no further refrigerant leak has taken place. Or even servicing your unit he would have punchered the tubes resulting in very slow leak of refrigerant resulting in no cooling or less cooling. It takes around a month to feel the pinch of it and the refrigerant. One fine morning after sometime the unit will run and it would start throwing hot air instead of cool breeze!

Mothers AC unit


That has nothing to do with the water. Sounds to me like it needs cleanning, (the water is not drainning toward the back of the unit) ,,(dirty filter, which its trying to **** air anywhere it can even thru the drain hole, or not enough slope, leanning toward the back so gravity can flow the water to the back of the coil! Thank you-very-much!
