2001 Tahoe Leaking Water into Passenger Side with AC on
I need help to determine the next step. Got under the car and blew out the drain hose, but it did not help. Need instructions for the next step of maybe disassemby of the air box, if that is what I have to do.

Re: 2001 Tahoe Leaking Water into Passenger Side with AC...
If indeed you've cleared the AC drainhose than it might take a while to get rid of the water that was built up in the heater box. If it has been a few days since the clearing of the hose it may be antifreeze that is coming from the housing. Check it with a clean dry paper towel, if it is red or green than your heater core is leaking and needs to be replaced. Thank you, Dana

ac drain pipes are on the passenger side front floor area (just about where your feet go) under car when cars heater core gets a hole in it lots of times antifreeze will leak inside car on floor try to get a small sample of fluid thats leaking out with a tissue or something (white In color) see what color fluid is ,see if fluid is slippery like oil or not (rub it between fingers)
Antifreeze= orange or green in color
Transmission oil = red or brown
motor oil = brown to black
washer fluid = Blue or drk orange
ac condesate= clear water (cold)
a couple things to look at if it has a sunroof the sun roof would have drain hoses that run down in each corner next you need to look at the cowl this is the section in front of the windshield that has a drain on it as well if you find nothing there the next step would be to remove the seats and carpet and sit in the car while running water over it either way you should remove the carpet and make sure it is dry all the way threw or mold will start to grow and you will never get ride of it not good for your heath other key spots to look at is if the windshield was ever replaced it could be a poor seal
Your AC condenser drain is clogged up, it is on the firewall in front of the passenger, engine comp, look for a little hose sticking out or a drain, get a piece of wire in there, probably gummed up or got bugs in there. The water should spill out once you get it clear. Hope this helps.
this is normal, water is the condensation leaking out,but if leaking inside the van then the drain is pluged up, the drain is on the pass/side outside the van on the firewall,blow air into drain or stick a coat hanger in to hole until water leaks out,
It may be a heater core. i say "may" only because im not sure if yours is located there. but this is something i have run into. look under the hood passenger side fire wall. look for two water lines going into the firewall. this will tell you where your heater core is located. should be passenger side, under the dash.
hope this helps.
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
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.
The evaporator drain might be clogged. Get under the truck or open the hood and look for a rubber nipple coming out of the firewall on the passengers side. Try sticking something in this hole to release whatever might be stuck in there, usually leaves or sediment. Be careful, don't go crazy pocking something in there. The evaporator core might be near the drain hole, you don't want to poke a hole in it.
Iside the car,in the middle of the console is a shallow tray.Its job is to catch the codensation that drips off the aircon.Same as you see hoses coming off home aircons.this is what is in the car.There is a hose,about as thick as a finger,that drains the codensation out through the firewall of the car and into the rear of the engine bay to the ground.There may be 2 hoses.One either side if its a split catchtray.The hose has either been knocked off or is blocked.Usually blocked.The tray itself gets dirt in it and this is where 'gunk' can buildup over the drain hole.Find the hose and shoot some compressed air up the hose or run some line trimmer cord up there.Hope this helps
Auto ac units have an outside drain for the condensation. If you ever noticed a car running and it looks like it's leaking something on a hot day it's the condensed water from the ac unit draining. What you have is a clogged or disconnected drain hose.
You need to find the hose and drain and reconnect them. Sounds simple, good luck.
