LeSabre :: Water Leakage In HVAC System
Jan 5, 2013
The water was not actually getting into the HVAC itself, but getting past the air inlet assembly from under the leaf screen directly into the firewall area. I will try a gasket maker that comes in rolls that I can press into place. there is no room for tools there.
Everywhere around the heater and AC module is dry. The foam on the inside firewall immediately under the air inlet assembly is soaked, yet the inside of the assembly is bone dry. I removed the entire to diagnose the leak. A light rain was enough to fill the back foot well with an inch of water.

My son's car overheated yesterday due to a sudden crack in the radiator. He had it towed to me. There was no evidence of a blown head gasket or cracked block, so I replaced the radiator. Since the battery was dead, I put the charger on it. When I did that, the heater/AC fan began to blow. The only way I could get it to stop was to disconnect the battery. Even the ignition switch had no bearing on the fan.
I do not know if the overheating and this problem are related. It may be just a coincidence, but it is odd.
This car has a slide to regulate the blower speed. It is not one of those "Select a temp" automatic ones. It will blow cold air out the AC vents when AC is selected, but when the OFF button is selected ambient air goes to the DEFROST vents.
I suspect a relay is stuck, but what relay, and where is it located?

I have an old 98 Lesabre, and it runs and drives great. When I first got it I had to do the Vacuum line mod on the programmer to get the HVAC to blow out the face vents. That was the best $1.60 and 30 min I spent on a car
That mod still works and was done about 1.5 years ago, the ENTIRE time i have owned the car the temp blinks when I start the car, but the HVAC has always worked fine so I paid no attention to it. That is until 3 weeks ago when I had to replace my intake manifold. I disconnected the battery without turning the system to "off". I have been doing a bunch of reading online, and it seems I may have thrown the system's sync off by doing this.
Right now my problem is this, colder air coming from the pass side then the driver’s side. When I start the car it will seem synched for a few seconds, then it will start blinking and both vents will go FULL COLD, eventually it brings the temp back up the d-side gets hotter than the p-side. I have done the following:
- gone through AT LEAST 50 on/off cycles
- Removed the 9c fuse to try to reset
- Pulled down the glove box door and watched both the upper and lower blend doors go through there whole range of movement (which they do)
- Tried to re-sync by pushing the temp full hot, then full cold a few times in a row.
Besides getting this scanned by a tech 2, which is my last resort, is there anything else I can do?

I have had my Camry for 9 months and unfortunately didnt know that water was going inside my trunk every time it rained, the car was washed, or snow melted! I took it to the dealer to have it looked at only to find out the trunk body seal needed to be replaced. I have had cars over 10 years and water in the trunk was never an issue.
This is my first Camry and I must admit I am not satisfied with the purchase. I hope my experience gets better.

Just noticed something strange. Haven't opened the boot for a few days and We have had some really heavy rain but today, when I did open the boot water, poured out between the carpet on the inside of the boot and the metal. Has water in the actual boot or is there some drain holes I need to check.

Leaking A/C water onto the passenger floor problem. If you’ve gone on a long trip and ended up with a pool of water on your passenger floor, you know what I’m talking about. It seems to be a common problem, especially if you live somewhere hot and have to keep your A/C on the coldest and strongest setting nonstop like I do. This is a very simple job and takes about 20-30 minutes.
All you need is: duct tape, a wire hanger, a few towels, and a wet/dry shop vac. (If you don’t own a shop vac, borrow one or rent one if you must, but it is a good investment if you don’t own one already).
Step 1: Remove the plastic cover under the dashboard. This piece just pops off, there are no screws, so give it a good tug down and outward and it should come off easily.
Step 2: Once you have that piece out of the way, reach up to the left corner of the carpet and pull it back, you don’t have to pull it very far to see the A/C drain tube.
Step 3: Pull the tube out from the hole on the firewall, and look at the end. If there’s water dripping your clog probably isn’t that bad. Take the wire hanger, bend it straight, and stick it as far up the tube as you can, wiggling it around and pulling it out to wipe off any gunk on the wire. Try to reach the metal pipe that the other end of the rubber tube is connected to if you can, but do NOT pull the rubber hose off the pipe, it will be hard to get back on. Also, be sure to have your towels ready because you may have up to a liter of water pour out the end when you unclog it.
Step 4: Turn your A/C on (make sure the car is fully on) and wait a minute. Look at the end of the drain tube. If it is dripping water quickly, and you don’t see much water coming from anywhere else under the dash, then you are done. I would suggest to still continue with the next steps just in case, but it’s up to you. If, like mine, the tube is fairly dry and you still see water dripping from further towards the inside of the dash, then your clog is further up the pipe and not in the tube itself. In this case you’ll need the shop vac.

This morning I went to put some stuff in my hatch to go to a job and looked at the paper towel role I keep wedged in the small little cubby in the front corner and lifted it up and it was SOAKING wet! I literally could squeeze the paper towel and water would come out of it (like you submerged a paper towel in water and immediately squeezed it out). Its rained about 1.5 inches in the past few days and my car had been sitting while it was raining but had been driven between the two storms. I WILL be contacting the dealer very soon.
The funny thing is my Genesis has a recall for the water Leakage through the tail light housing.

I have a concern has any experienced seeking water where the aux battery goes in the hatch compartment.? As well as where the emergency tire goes? I was taking the battery out this weekend to take it home and charge it, and I saw the flood of yellow water, how does this water get in the car?
Another question/concern when reconnecting the battery in reverse the positive terminal connects first and then the negative but I was experiencing some sparks pointing my way, I was wearing my plastic/gummy gloves but is this normal should I worry?
And what would happen if I forgot to reconnect the little black pump (the little hose that connects to the battery)?

My 2003 Passat has a musty smell coming from the HVAC system that just won't go away. Have resealed pollen filter and had airsept treatment (this worked for a while, but now the smell is worse than ever). Two dealers have tried (and failed) to fix this. It's so bad I can't take passengers in the car.

I am getting water at the very front of the trunk, nearest the passenger compartment. Might be the drains in that vicinity that might be plugged causing an overflow there .Rest of the trunk is dry. The only wet area is immediately underneath the pull-out "shade" thing that has to be in place for the top to operate. Some indication that the water is coming from above that, since it is wet also.

We have water leak issues for close to a year now, very frustrating. Not heard much of B7s leaking so I thought I'd stop in here and check it out. Great car to drive, only other issue we've had was the cold weather inactive drivers door lock as seen by many others.

I have a 2013 Camry SE that is, out of the blue, not blowing any air from the HVAC system. I checked the 2 A/C fuses any they are ok. The lights light up on the control panel like normal and the rear window defogger works correctly, so I don't think it's the control panel. I can't find any fuses or relays relayed to the blower motor in either fuse box.
What else should I check? The car is still under warranty (for a month!) but if it's a cheap and easy fix, I'd rather save the hassle of giving it to the dealer for a day and fix it myself.

Our 2002 Camry SE V6 incurs a burning odor through the HVAC system after braking from moderate or higher speeds (at low speeds, this does not happen). It can last for a few seconds or a few minutes and then goes away (it does not happen while in motion). I cannot smell anything outside the car.
The car was inspected & serviced two months ago with no issues found. The front valve cover was replaced about a year ago but the back valve cover was OK to leave as is.
I would want to say it is the brakes or the snow tires causing the odor but it is strange it only smells inside the car.

I drove about 25 mi today, made a brief stop and then continued home. On the return trip, the system would not blow any air in any mode at all. While driving, I cycled it through various modes and it would not do a damn thing. Later in the day I started up and it worked fine... What might cause that to occur?

Clear water comes into car my Corolla 2011 on drivers side and both the passenger and drivers rear floor panels. I checked and not coming from the body. Think it's from A/C but it's a lot of water. Front passenger side is bone dry. Looks like it may be coming from the center console and spreading out. Could the A/C evaporator drain be plugged. If so where do I find the hose?

Discovered a water leak on the A pillar driver's side (note right-hand drive)? We had a down pour today and my car has never exhibited this before. I got in my car today and noticed that there was a wet spot at the top and a wet spot under and to the side of the tweeter. This seemed to be quite soaked as pushing on it you could feel it was wet. I checked around the A-pillar and it goes up a little into the roof lining (about an 1/8th of the way on the top of the door ). Today , I heard a small gush of water, but that was about it. The car was on level ground. How do I take off the A-pillar so I can see if something has jammed up or something?

2003 Hyundai Accent 4 door. Well its been raining here in Portland Oregon non stop and this morning I went to get in my car and smelled a mildew odor so I took out the drivers floor mat and the carpet was soak. Then I laid back the carpet and that grey spongy covering thats under the pedals was soaked to the bone like a sponge.
I did a test with a water by putting the hose on top of the roof of the accent and turning it on full bore and nothing leaked in the car. I sat in their for a good 5 minutes with the hose blaring down the windshield and door sides. I even took a jack and lifted the car up too see if there was any cracks or a rusty hole underneath but nothing. So Im completely stumped on this I do have A/C and the drain hose is clear since I have been using my defrosters and the A/C pump kicks on.

My 08 B6 wagon has a very foul odor emanating from the HVAC system. It started after my wife washed the windshield with vinegar to get rid of some scaling from the bizarre water we have here. She thought the smell was from some of the vinegar running off the windshield. Well, that was several months ago and the smell is no better. Just recently, the temps have been down enough to turn off the AC switch and the smell is even worse.

Two related problems:
1) Our 2008 dodge grand caravan's recycled cabin air/exterior air flipper is broken. You know, makes the clicking clunking sound until it gives up?
2) Unfortunately this has made the exhaust smell that much worse.
Usually when you drive above 35mph you don't catch engine fumes, but when its anything less you fear you're poisoning your family into early cancer. Obviously we have a leak in the HVAC system somewhere and anytime we take it somewhere for service on something else they just shrug their shoulders.
How to locate the leak so I can keep the engine compartment out of our a/c?

I can't seem to figure it out. I've been having a water leak in my gti. Here's the facts
-rear drivers side floor is soaked wet, nowhere else.
-I pulled up the carpet and carpet pad and wiped the floor dry.
- poured water in sunroof drains and didn't see any new moisture, water ran out of the drains on all 4 corners.
