SOURCE: I have a 2000 GMC Yukon. The air conditioner blows

I have a simular problem in a 2002 Tahoe. It turned out being and actuator that controls a flap door that separates the air flow from the heat box. When this part goes bad the control knobs are useless is what they control don't work. According to my Chevy Dealer this is a common part to go bad. This part is located in the rear or the truck behind the passenger side wheel well on the inside of the truck. In this area is a system simular to the system that is in the dash. There is a heater core back there and this is where your rear heat comes from. The same as the front system in your dash. When this actuator fails it will be in the open position on the flap door that goes to the heater box. This more than likely is your problem. I currently have a 2004 Sierra. I have a simular problem again. There is 4 actuator door in my separated climate control system. I can't tell you which one is bad but I can tell you that more than likely this is your problem. You will have to get under the dash and notice which actuators move with your switches and which one does not. It will be a little black box. Maybe 1/2 thick and 3 inch by 2 inch estimated with a little round white piece of plastic that fits the arm that goes to these flap doors that direct the air to wherever your switches are telling it to. Price range from 50 to 150 bucks at your local parts store. Good Luck.

maybe theres a pin hole from rust in your fire wall. On my 1993 gran prix it had a pin hole and right by the pin hole in the fir wall there was a little lip in the metal and it would hold water for sometime.

-- 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 lines running horizontally and attached to the engine compartment firewall
-- locate the hole in the engine compartment firewall panel behind the small diameter metal brake lines
-- this hole leads to the drain opening in the air conditioner blower box mounted in the passenger compartment
-- follow the brake lines 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 lines
-- insert a short length of stiff wire into the hole through the engine compartment panel to unblock the drain hole

Water leaking from under the passenger side dash board. Everything appears wet with condensation. How to correct this problem? This seems to occur when using the air conditioner.

Hi Earl there is a drain hole in the bottom of the the heater box it could be blocked. When the car is running and aircon is on it should leak out on the road through a small pipe. if the ground is dry under the car after running a while it must be blocked. The easiest way to clear it would to blow up it gently with an air line to go downwards would involve a lot of work. Hope this helps. Regards Jim...

1999 isuzu amigo water in passenger and driver floorboard no antifreeze smell at all.

this sounds like a build up of condensation (water) possibly in your ac/heat ducting or possibly in the plastic casings under the dash that house some of the heating and cooling components. cold ac components close to warm or hot heating components will lead to water build up this is why there should be a drain tube for the plastic housing under the dash board that leads to the outside of the vehicle. this drain tube may be clogged or may be disconnected and not draining to the outside but instead its allowing the water to fall into the area under your dash board. FYI you can sometimes see these drain tubes drip water on cars that use their air conditioner a lot, it looks like the car is leaking water from the bottom but it's just the water draining away from cool air conditioner lines on a hot day and draining properly to the outside of the car and not on the floor inside.

2003 Mitsubishi Lancer started to leak water on passenger side under dash.

I am guessing that this occurs after you hae been running the Air conditioner and is COLD water. I ran into the same problem and found that the drain line from the Air conditioner pan was clogged.

If I remember correctly, the drain line comes through the Firewall on the drivers side. I was able to push a small piece of tubing back through the line and loosen the clog. A bunch of junk came out and I have driven last summer and so far this year with no more problems,.

Water on floor passenger side after it rains and after air has been running 2000 grand prix

Ac hose leak?
leaking heater core?

Hint: it leaks when it RAINS

If it were related to the heater core or the AC drain, it would be leaking when it is not raining also, so those diagnoses are not logical.

The grand prix has a long history of floor leaks from seal failures around the air intake under the windshield cowling, where RAIN water runs in.

2009 Mazda 3 found water puddled under floor mat on drivers side, where is it coming from?

Could be condensation from the air conditioner. This normally drains out a tube near the glove box, onto the ground. If this drain tube comes off or is clogged, the water will drain into the interior of the car instead.
Could also be a leak around the windshield, door, or sunroof.
When do you notice it most? Warm humid days, or after a rain or car wash?

Water leaking under the dash

If on the passenger side when the air conditioning has been running, most likely a clogged air conditioning drain hose. You can located it by reaching under the dash in the passenger foot well. I have cleaned mine by removing the end of the hose from the firewall grommet and inserting a wire in the hose to clear the clog, then used a shop vac to **** out the debris through the hose. I did this several times. Take a container to catch the water as once you clear the clog the water will come running out all over your head.

Exact location of A/C drain tube

Open hood, near center on firewall at back of engine, below and about midway between the AC lines and steering column, a small rubber "L" nipple should be visible, if not, line is draining under dash at the firewall, if it is, it may be clogged again. Find a mechanic that you trust and have them them clean it out for you.
