Air conditioning drainage tube blockage

Check behind the glove box if u fold down door and look in it should be there

open glove box (some models have little shock on right side to allow for box to open farther) once removed ac filter is directly behind glove box

Does the air blows through the dash board vents. Does the selector is functional, that means you can force the air stream through wind shield, or vents or down to the legs. If these things are OKthen check CONTROL PANEL.
Remove the trim plate surrounding the center instrument panel. Detach the electrical connectors and remove the control panel.

Probably Air conditioning condensation (normal) or rain water build up in wiper motor area due to leaves or other debris clogging the drain tubes. If its leaking in car the drain tube into the engine compartment is plugged up. Just needs unplugged with compressed air or a piece of wire.

There is a condensation drainage tube that runs from the condenser to the bottom of the vehicle. I would assume this tube was clogged by somthing and the excess water was building up and decreasing the efficiency of the a/c. I would remove the drainage line at the bottom of the ac condenser and make sure nothing is blocking the drainage. Hope this helps!

The drainage tube for the evaporator case is plugged causing the the condensation to drain inside instead of outside the car. The car will probably need to be lifted to find the drainage tube. Use a pick to gently remove the debris blocking the tube. You must be very careful as not to puncture the evaporator core.

you have one of two things, either a build up in your evaporator box, (which is caused by blockage in the drain tube, or you have an air picket in your coolant system, which means it will have to be bleed.

Hope this helps

water dripping from under the glove box area is usally a sign of water in the heating ducts. water runs down the windshield and goes under the cowel, then instead of draining, it some how enters the air intake for your heating system. Take off your wipers, and remove your cowel, you will be able to see the air intake (on the passangers side) and the reason why the water is being directed into it.

If your car has a sunroof, there are drains from the front corners of the sunroof, and they drain down the sides of the windshield pillars, and then empty out on the ground.

What I would do is open the surnroof, and pour water into the front corners, and then oobserve where the water drains out. If you have a difference in water drainage between the left and the right sides, I would think that you may have loose sunroof drain. They commonly come loose at the sunroof corners. This will allow the water to pass down the windshield pillar, and onto the floor.

Also, I would check the condensate drain tube for blockage. Pull back the carpet, under the glove box, and fins a black hose that pokes thru the firewall. Pull it out, and see if it is blocked internally. If this tube is clogged, water will build up in the heater box, as the black tube is the drain for the heater box.

One of the two above solutions will cure your problem. I see both quite often.

There should be a cabin filter. Call the parts store to see if they stock one for your car in particular.

Cabin filters are located in stream of the outside air flowing in. I know on a '99 Galant, you just had to take out the glove box, loosen two screws, and out she slid.

It'll be right near the blower motor, above the passenger's foot rest, behind the glove box. Simple hand tools will do it.

Be careful when pulling it out, as it may have leaves and acorns or fur all over it. Simply slide in the new filter and you're done.

You'll be surprised at how much better it'll smell, and how much harder your A/C and heat will blow without the constriction of a dirty filter.

Most cars have the cabin filters behind the glove box, but if not there, then they'll have them under the hood, on the firewall, on the passenger side. Usually inside a small black plastic box.

If your car DOESN"T have a cabin filter, then the musty smell is stuff that is sitting in the heat/ AC system. You can try spraying pine sol or Febreeze down the air intake hole for the system. Mind you, this is not the same as the air intake for your cars engine!

The air intake for the cabin filter will be on the passenger side, under the hood, most likely under a plastic cowling of sorts.

Good luck!
