Question about 2008 Mazda Cx 9

2 Answers

How do I clear the AC condensate drain on my 2008 CX-9?

I can hear water sloshing under the dash and some drips onto the pasenger side carpet whenever the car is turning left. The AC fan also makes a louder blowing/hissing sound when turning left, like the air is passing over collected water.

The first place I would look is on the firewall from under the hood. Toward the passenger side, (I think) you should see a rubber nozzle coming out of the firewall. This is the condensor drain, and chances are of course, it's clogged up. You should be able to easily remove it. Upon doing so, the condensor should drain the collected water. Then, you'll have a good oportunity to clean the nozzle and put it back in.

I hope this helps you with your problem! :)

Hello... It is possible that the condensation drain tube for the AC could be disconnected. This just happens sometime.This in turn allows condensation to settle in the AC Module and drip into the passenger compartment.

I recommend taking the vehicle to a mechanic for repairs...

Good Luck... Hope this helps...

    Not exactly the "Fix It" solution. The problem is the drain tube is blocked. It will happen again and again until the drain tube is unclogged. Can you help me locate where it exits the vehicle?

WET CARPET ON DRIVER'S SIDE


Could be the drain for the ac is plugged up. Usually when this happens the passenger side floor gets wet, but it could be coming out on the driver's side when you take a right turn.
The drain should be on the bottom of the firewall near the floor, you should see water dripping onto the ground when the ac is on.

Recently every time i drive my 1991 pathfinder and take a corner water just sloshes out onto the passenger side floor. any idea what causes the water?


the most common reason for this is the ac drain is plugged and water is filling up inside the heater box, you will need to locate the drain from under the truck on the pass/side and blow air into it or use a hanger to clear, you will see water pour out, this is a small hole sometimes it will have a rubber end on it with hole in the middle, clear opening and drain box, this is common, when ac is on you should see water dripping out on the ground from pass/side, it comes out through the firewall . good day.

Water under pasenger side carpet not from heater core


Find the drain for the A/C located under the hood, firewall, nearest the bottom of the firewall. It will be a black tube and if plugged, the condensation from use of the A/C (which also turns on when the defrost is used to evaporate moisture) will back up into the blower box and drain onto the floor. Long term effects include; rotted floor board, mildew, shorted blower motor and loss of effective defrosting, heating and cooling. Use a coat hanger or other long thin item to clear the drain and allow the water to drain. The system will be much more efficient. Let me know if you need anything else.

Hi there, My Touareg 2008 with A/C I found that the carpet under my feet is wet and there is some water lakage coming from the right side of the driver's foot well near the petrol pedal. The water is cold...


Find the drain under the car for the ac condensation,and clean it out with air pressure.It will be directly below where the ac lines go into the car.

I have a 2003 Volvo S60 that ends up with a wet carpet in front of the passenger seat whenever it rains (Seattle). Also, when I am driving and turning left or right at corners, I can hear water sloshing...


The drain for your A/C may be clogged causing the water to accumulate. You should be able to locate the drain from under the vehicle on the pasenger side, perhaps there is an accumulation of debri such as leaves for example. Also, sunroof drain may also be blocked. I can say I have seen this problem before, and its a good place to start. Good luck

Water dripping onto the floor on passenger side below the dash broad


Under the passenger side of the vehicle, near where your feet are, should be a drain tube. This get clogged from time to time by road grime and usually insects, so carefully use a small screwdriver to clean it out. If this clogs, the A/C system cannot remove its own condensation and it backs up into the car.
