AC condenser drain plugged

When I make a sharp left turn I hear a swishing sound. Dealer service says the drain plug for the ac condenser is plugged and the backed up water is being hit by the fan blade as is sloshes sideways when I turn left. They estimate $900.00 to repair this. Is there anyway to easily clean this drain and where is it?

    I had the same problem, it cost me $500 to fix it then the problem came back. The best thing to do is not park around trees.The leaves plug the drain.

I had that prob with mine. The drain in the engine compartment was blocked. Good luck trying to find it yourself, even my mechanic had a heck of a time getting to it as it's on the firewall.
Cleaned it out, blew it out and all was well......For several weeks then started all over again.

SOURCE: it sounds like water is swishing around when I

You can check your drain plug, but also consider your coolant system. It may have be be bled. The coolant systems are closed and if they get an air pocket it will move around and make that kind of noise at times. If you had it flushed, which at this age you should have by now, they may not have filled it up all the way. It can be tricky.

Hope this helps.

You need to clarify your question. The AC does not use water.

A/C Hose Blockage on 2001 Olds Aurora

It sounds like the AC condensation drain is plugged, a very common problem. The drain tube is at the base of the engine firewall on the passenger side and can only be accessed form under the car. The best thing to do is remove the AC/Heater blower motor and clean out the leaves or mouse nests that are causing this plug in the water condensation drain pipe. If the drain is clear you will see water under the car on most days (high humidity more water) after you stop and have had the AC turned on.

Swish noise when turning with fan on.

The AC condenser is not able to drain the condensate and it is trapped. Locate the condensate tube and clean it out.

Location of ac condensate drain , it's plugged and leaking into the car

The weep drain is located on the left and right sides of the firewall and you may see a rubber tube sometimes, and hear a sloshing of water building up, unless, it's all leaking onto your floor.

The front passenger floor gets sopping wet after I drive and turn off the truck after having had the a/c running. It only does this if I had the a/c running. What's going on? 2003 Dodge Dakota 6 cyl. Aoto...

That sounds like the AC condensation drain tube/hose is plugged up.

The AC evaporator/core condensation drain tube is located on the passenger side of the fire-wall towards the bottom of the fire-wall, (it resembles a heater hose that is coming off from the fire-wall and it connects to nothing, and it is just to drain the AC condensation) and it is easily viewed from under the vehicle. Use long pipe cleaners folded in half to clean out the AC drain, and be very careful that the AC evaporator/core, or the heater core is not damaged from using any hard or sharp objects to clean out the AC drain.

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

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! :)

I I have a 98 plymouth breeze i get a swish sound

The AC Clutch is going and is slipping, thus the swishing sound..sorry. When the Defrost or AC is turned on the Clutch is Engaged. And yes the AC Unit replacement is recommended over trying to have the Clutch replaced. Most mechanics won't even try rebuilding an AC Unit.

Water in the Heater system

Do you have a drain plugged outside under hood on firewall. Looks like a rubber elbow or similar. Gently poke something inside, not too sharp or far to clean out. If all else fails try a little compressed air to dislodge.
