Where is the ac drain hose

If the swooshing sound is up in the dash area..and you have not lost any coolant.. chances are you have a plugged AC/Defroster system drain hose.

On a hot humid summer day when folks are running the AC you may have noticed puddles of water under your car and others. This is the excess moisture being pulled out of the passenger compartment. It collects and drips out of the drain under the car.

You probably don't have that puddle forming anymore.. the drain is clogged. Next time you have it in for an oil change at a decent shop.. have them locate that hose..give it a blast of air.. to unclog it.. and drain that water..

If the sound is coming from somewhere else.. best to locate it and drain it.. or clean the drain holes..doors etc..

Best of luck!

Look under the hood,and look at the ac lines,where they go into the car at the firewall.The drain will be directly bellow the ac lines,look for a hole,possibly on the bottom of the blower box,use air and a blow gun with a air tank to blow into the drain to clear it,watch out,it will come out like a waterfall.If this was at all helpful please rate thank you.

Hello,

The drain hose does not actually exist. The evaporator box (also holds the heater core) is partially in the engine compartment and partially in the cab on the passenger side and excess water from running the AC drains immediately into a frame member. This is a unibody vehicle. There is no way to access the end of the drain tube to clean it out.
The drain hose runs through the firewall and into the frame There is no way to get to it from the outside of the vehicle. The only way to relly reach it, is to remove the housing.
Sounds absurd,but that's the frantic truth about this car..

Good luck.

There is a hose that comes through the firewall on the passenger side, it is the condensate line for the AC unit, it gets clogged up with bugs, dirt, wasps, etc, clear it out, it will flood the floor if it is blocked. It looks like a little bent rubber hose, it doesn't look like one, it is one. Check it out.

You will need to have the heater/ac box drain hole cleaned out,this drain is located on the firewall coming from the heaterbox, you should see a small hose sticking out of firewall on the pass/side,near the bottom, blow air into it and water will pour out or use a coat hanger and slide into drain hole gentle and water will run out.

outside the firewall ,under the internal ac unit ,just above the steering rack ,a rubber hose

Yes, they typicaly about the same size as a pen. Make sure that it is just water comming out, and not coolant. If water, this is normall from condinsation, if coolant, you will need to change the heater core.

You will have to find the location of the condenser, their is drain , to drain the accumulated moisture, which is created when you have the AC at full cold! This drains the moisture outside of the car !

the moisture dripping into your passenger compartment is condensation that is supposed to be dripping out of the a/c box via a tube that runs along the firewall to the bottom of the car(thats where the water on the ground comes from on most rigs that have been running a/c for a while). it sounds like the drain hose, or the base of the a/c box where the hose attatches has gotten clogged. if you can get to where the hose attatches to the box, remove it and blow air through the hose. before reatatching the hose, be sure there is noting blocking the niple on the bottom of the box. you should be able to get a pick or small screwdriver through the hole to clear the debris. if that fails to work you will most likely have to remove the a/c box (very difficult and lengthy process) to clean the drip tray in the bottom of the box. if it comes to that i would recomend modifying the box somehow to create a larver drain hole, and allow for a larger drain hose. if its clogged that bad after just 4 years, you will probably experience this problem again without enlarging the drain hole. hope this helps

-- locate where the air conditioner blower box is attached to the passenger side of the firewall – see photo #1 – look to the immediate right at the top of the gas pedal arm

-- condensation flows toward the front of the vehicle through the firewall at the leftmost edge of the air conditioner blower box – drain channel
-- open the hood and stand next to the front wheel on the driver's side
-- look down at the firewall over the battery and to the passenger side of the brake master cylinder – see photo #2

-- locate the small diameter metal tubes running horizontally and attached to the engine compartment firewall
-- locate the hole in the engine compartment firewall panel behind the small diameter metal tubes
-- this hole leads to the drain opening in the air conditioner blower box mounted in the passenger compartment
-- follow the brake tubes as they run from under the vehicle and turn toward the front wheel on the driver's side
-- locate the hole in the engine compartment panel behind the brake tubes
-- insert a short length of stiff wire into the hole through the engine compartment panel to unblock the drain hole
