Question about 2004 GMC Envoy

Leak to the passenger side floor board.

When the air conditioner is run and its hot and muggy I get water on the floor board. It is not anti freeze, so I take it that its water from condensate. I would like to know if there is a weep hole that is plugged and how to clear it.

There idef. a drain for the water and is located below heater box on pass. side under vehicle. usually rubbertype hose with sort of closed off end maybe 2" long. (sometimes they are hidden, look carefully) i use shop comp. air to clear but a straight piece of wre may be just as good. also consider replacing cabin air filter behind glove box. probably restricted as well

Yes there is a weep hole. it should be located under the cooling coil near the firewall. it may look like a small hose and probably has dirt/mud/trash covering it.

Why does my Buick Rendevous, 2005, leak water into both front floorboards?


Is it leaking water or Anti Freeze?
If it's Anti Freeze you can pull down the rug or floor mat to check, you should also smell the Anti Freeze. This means your heater core is leaking & has to be replaced, if it's not leaking bad you can try a sealer called Aluma seal (my spelling could be wrong),looks about the size of a roll of dimes, most auto stores have it.
If it's water, my guess is the AC condensation hose is blocked. Does it leak only when the AC is on? this hose runs outside, usually on the
passenger side behind the front wheel, when the AC is on & condensation builds up, you will see water coming out on the ground, this is normal, but if that hose is pinched or blocked the water could end up running onto your floor. Hope this helps.

Honeywell troubleshooting


First.... are you sure it is "water"??? If it is, the likely source is condensation dumping out of your air conditioner system.... which is normal. Also, you need to remember that the air conditioner operates for other reasons than just cooling the passenger compartment in the heat of the summer. In many vehicles, the air conditioner also runs during the operation of your windshield defroster. Therefore, some water dripping on the floor of your garage is normal. BUT, if it's engine anti-freeze (or some other fluid) we're talking about, that's a whole horse of a different color..

Air conditioner leaks on floor


Sounds like the outside drain is stopped up.
There should be a tube coming out of the firewall near the passenger floor.

Floor board on passenger side wet after running a/c unit 2005 ford taurus


Could be the drain tube is partially clogged. It is usually located on the fire-wall or down towards the floor pan under the car. It is usually close to where the A/C lines go thru the fire-wall. About 1/2 inch diameter sticking straight out but may have a 90 degree elbow pointing down.
Also, its been extra hot and humid all over and moisture could be freezing inside the unit when on MAX A/C, then suddenly melting when switched to normal. This opens the outside air door and allows warm/hot air into the unit instead of recirculating the cold air inside the car. The drain may not be able to handle a large, sudden quantity of water.
Perform a "driveway" test. Open the hood, start engine and run the A/C on normal with the windows or doors open. Locate the drain tube by looking for water dripping. Once located twist 2 or 3 pipe cleaners together and verify the tube is clean. Then close the doors/windows and switch to MAX A/C. Check for water dripping. If it stops dripping, water is freezing inside and now you know why!

H3 hummer 2006 model.....hot floor board, passenger side


The hot floor is the catalitic converter. It may be bad, but you need to find out why it got hot. usually lean codes will be present with this problem. could be a bad vacuum leak. mass air flow sensor could be bad. as far as the water being a 2006 I do not think it is the windshield, probably the drain is plugged up for your a/c look under the hood, passenger side, there should be a tube that hangs down around where the a/c lines go in to cabin. you can try to back flush it or run something up in it to free it up. good luck

Water leaks on floor board of passenger and driver side


Most cars have the air conditioner drain on the passenger side just in front of the fire wall , if this becomes clogged it will back up and run out in the area you indicated. Look for the drain hose and make sure it is not kinked or plugged!

The problem you describe could be from condensation. On very humid days, I have seen some condensation from auto air conditioners blow through the ducts. If you run your A/C in the heat/defrost mode (it probably comes on by itself when you run the defroster), that could happen, and the water could be leaking down through the heater vent. It could be a sign that you're A/C unit is low on refrigerant, in which case, you'd need to get the system serviced.

A leaking door seal on the passenger's side could also cause that, but only if it was raining. If I assume that this is happening when it is not raining, the A/C is the only place water could be coming from. The only other, remote, possibility is windshield washer fluid, but you would probably notice that by its odor.

Hope helped (remember rated this help).

Water on Drivers side Saturn SC2


Is it antifreeeze from heater core or heater core hose leak?  Is the leak pure water, or maybe something else?
Put it in the garage again overnight with an old white towel in the drivers foot well, best if you can find a way to stretch it from drivers seat forwar to firewall and keep it off of floor mat.  Check it before you go to bed,  then in the morning if no leak found yet.  see if the color/location of the spot helps you identify the source.  I think the heater core is under the dash center.  Anti freeze is green/yellow or orange.
good luck
