Another big one is where the air enters the cowl through that almost square box on the top passenger side. That foam is a gasket which mates with a riser that protrudes through into the cowl. That foam deteriorates and water that enters the drivers end of the cowl, and washes over to the passenger side, can drop down into that opening. Actually, it's probably getting sucked in if your blower fan is on. (I have to wonder if the blower motor getting water in it isn't part of the cause of my melting ignition harness accessory wires and blower switch plugs.) If you've ever seen little pieces of foam coming out of your vents, this "gasket" is one of the places it is coming from. There are a couple of decent fix videos here on UA-cam, where they cut into the cowl under the plastic cover on top and caulk around that riser. Seems to work. I'm going to do a THOR cowl induction and try to seal mine up through the hole I have to cut for the air filter. Good video.
OUTstanding video! Great break down of the entire heating and cooling unit, with the take apart and demonstration. I just bought a '97 wrangler and the passenger side footwell was soppy wet this morning. My engine bay is plenty dirty and the water is clean, so not the heater core but likely blocked condensation opening. Great work. Thanks!
I had clear water dripping from underneath the dash. I did as you suggested and stuck a screwdriver in the drain hose to clear it. Eureka!!! There had to be a half gallon of water come out. Your suggestion worked perfectly!Thank you for this video!
This was super helpful. I was able to find a little heater hose elbow at autozone that’s just a fit. Part#70646
LOVE this guy. Any Jeep problems his videos always pop up
Fantastic explanation. Thank-you for sharing your expertise and knowledge. You are AWESOME!
This is a really good video, covering a lot of different problems. I would get a puddle of water where the passenger in the backseat would put their feet, every time it would rain. Apparently it was coming through the vent that was under the passenger front seat.
Mine was due to missing the radio antenna grommet! Hard to find but relieved it wasn't much work to replace.
this video just reminded me i need to fix one of my jeeps, we took off for fla in july, got about half way there and the passengers side floor started looking like lake erie, pulled over, couldnt find the hose anywhere, talk about a long hot ride through fla, georgia and sc in the midst of summer.
Congrats on 100,000 BleepinJeep.
A lot of people uses an air hose to blow the lines out also. I've had to do it on a ladies 2014 camry, it kept soaking her passenger floorboard. Sprayer seemed to clear the lines out and it fixed her issues. I tried the coat hanger as well but couldn't get a real good angle with it under her car.
Very easy to understand. Awesome video!
Will be checking this at the weekend, thanks. My water is on the drivers side but guess that's because I'm in the UK with RHD.
outstandingly informative video. thanks.
if you could make a video about how to unclog a Heater Core that would help a ton! i have to do it to my WJ.. but i havent gotten to it yet. You the best Bleepin Jeep!!
Thank you guys for all your videos, great help. I now suspect the wet passenger side floor is a leak from the windshield or something else.
Great video and explanation 👍 thanks a bunch
Excellent video! Thank you!
Great video mate
You should do vid on rusted out floorboards.
no clue why jeep thought it would be a good idea to put the ZJ's a/c drain in the frame rail... pain right in the ass. fixed now, thanks to RTV and the top of a water bottle 😂🤘
Thank you bro big help have a 97 jeep wrangler tj .....looks like I have to replace the heater core lol....
I have a 2000 Cherokee. The passenger floorboard would fill up in a good rain over night. Found it was coming in around the heater blower. Water ran down the windshield past the hood seal along a drip edge and dripped onto the blower motor, ran down the inside of the firewall and would fill the floorboard up. I did some water division tricks. Seems to have taken care of it. If I ever have to pull the air box I'll reseal it.
Mine does the same thing
jayless1022 useless comments like these I despise.
Awesome. Thanks.
i am going to look at my ac drain. dirt dobbers are a problem out here!
In depth informative video. Thank you. Could you advise if the water is dripping from blower motor after hard rain or car wash? I can see sudsy water in the area of the cabin air filter with the recirc door open.
That would make a nice coffee table ornament.
Great vid as always. How do you know if you have to remove the heater box? My sons 2001 WJ is leaking from the passenger side pretty bad.
on my 2000 JGC, it's the door seal leaking. It would be a big mess if I were to take this big box out. Before doing this, look else where first.
ZJs have a problem like this but the tube on the Condesation drain either falls off or the factory doesn't put one on. There is a video or forums available on cutting a hole into the wheel well because unlike the XJs that have an easy access the ZJs is between the wheel well and the firewall. A 1inch by 2 inch cut or 2x3 for easier work is needed. Then you place a new hose over the end and/or seal up the hole in the firewall so it can't run back into the cab.
Huge fan of your videos, very helpful. I have 97 jeep cherokee and for years the passenger side leaks when it rains. I want to replace the whole hvac unit for a new one with new gaskets but I can't find the unit for 97 -01. All I see is the units from 84 -96 . Do you know where I can buy a new 97 hvac box?
Not every scenario although I thought mine was windshield. Front floors are rusty with pin holes in it and a large hole I found when I pulled the carpet. So here in Florida it rains torrentially. I went out twice in the spring to two inches of standing water in the floor. Well finally took the hose and on the drivers side, let it run in the vent where the wipers are. Water started coming in and I was able to locate the issue. Some of the water was running inside the engine bay on the firewall and into the grommet where the hood latch is. RTV Silicone on the inside, let it cure for 10 min and plugged it back in, and on the outside a ring of silicone RTV around the hole and good to go... a 12 hour rain later and no more water... now fixing floorboard.
I got a tube from lowes and strung it down so the water could not come back onto the passenger side from the dry rotted seal that went through the fire wall. That prolly would have fixed it. But I also cut out the foam seal and used a silicon adhesive sealant to seal up the firewall. Hopefully cutting out that old seal was a good idea because I feel like I could have just left it and used less sealant to make it a good seal
i have 2 97's and they leak under the heater box from where theres sum foam strip when it rains or carwash it must come in the cowl then the box
Also check sunroof drain tubes
Matt do you have a video on how to delete the AC on the 2000 XJ?
I like how you explain things do you have any videos on parasitic loss my battery keeps going dead and I'm not sure where it's coming from
yes i do, google "bleepinjeep parasitic draw"
my jeep leaks on passenger side and drivers side, however; i noticed when it was parked overnight in the rain went into it there was a lot on drivers side i already found that the window seal leaks... still searching for other shit
if I bring my 1999 xj to you can you do a heater core and evaporator change? Im in NY but travel to PA often. cash on hand !
water will get into the cowl and drips through the fresh air blower area under the dash and puddle on your passenger floor
Man...!🤔
That's the best video of my problem thank you so much, I love you...♡♡♡😙 keep it secret...😂😉
Great video, I have a heater core replacement in my future. BTW Radiator Express has copper heater cores for 1994-1996 XJs.
What happened to the t-shirt model?
Another potential 5:01 reason for a clogged condensation drain hole is … off-roading in deep mud. Ask me how I know 🤔
Hmm well sure does seem to be my heater core is leaking, as i'm having green coolant on my passenger floorboard, which in the long run shouldn't had surprised me as I had to replace the radiator in the jeep the first 2 months
If Im leaking from the AC drain because the seal is ruined, could I use something like silicone to reseal around the drain without removing the HVAC box?
Hi! I hear a gurgling noise of water under my dashboard on my 2014 ram 1500
when I turn on my A/C and also when I Have the heater on. I hear like a small
water rushing or boiling BUT no water anywhere showing leaking.
What do you think it is?
What's the rubber tube that runs under the passenger side carpet? My last two XJ's all leaked at the windshield on passenger side.
I do have a question I couldnt find an answer to. I know on my 97 xj the AC humidity vent hose runs in the frame and I may need to clean mine out. Is there a place to drill a hole to stick wire in there? or know another way of fixing short of taking out the heater core unit?
I have had TWO different types of leaks. 1-was the heater core and replacing it SUCKS! Luckily I didn't have to take the whole box out just part way out and it still is super annoying and then I had to get the line vacuumed to get the air bubbles. 2- was the AC condensation drain which water would run out the straight tube and right back into the cab because some idiot decided that open cell foam was good choice to seal it. That was an easy fix and super cheap fix once you drill out a little hole in the wheel well to get to the drain.
Mine are at on both front drives and passengers keep getting wet. No reason in pass week. I have floor mats down. I went to clean my jeep lifted the mats and rugs are wet. Not soaked.
Ive witnessed my jeep leaking when it was raining but under the glove compartment, what do you think it would be? I drive a 1998 jeep cherokee unlimited 4x4 4.0L
I just brought in my 2000 Jeep Cherokee Sport for horrible leaking from there and it turns out that the HEATER CORE BOX WHICH IS PLASTIC IS CRACKED and they can't find another one so I am basically screwed. They wanted to "patch" it but how long is that going to last and it would cost almost $400 just to patch!!! It only has 103,000 and now I can't drive it b/c my floorboard was soaked under the rug and I'm not putting up with it no more....too many problems and I don't drive it but maybe 10 miles a week!!! Sick of it. So it's sitting covered until I can fix my garage door and store it until I can get rid of it!!!
Hey man love your vids. I have a ac ? On my 98 zj the ac will blow cold for a while but then all the sudden it starts blowing warm. Any help is much appreciated.
maybe the compressor is shutting off
I see a leak from heater boiler combination area and wet driver side (left side) I clean AC drain hole engine side.. ? any solve?
What year was the XJ you pulled that out of? 97-01? I'd like to find what a '96 will look like, and a fun added bonus, it's factory RHD.
Okay so what I’m hearing here & from other videos is that if it is the drain that’s the problem then the water will be on the passengers side correct?!!? My water is on the driverside. I thought it may be this very problem but after watching a few vids I’m thinking it might be something else. It’s been raining a lot the past couple of weeks here in NYC. My carpet insert isn’t wet, but under it on the floorboard is wet like someone spilled a cup of water.
Check out my video on how to diagnose a leaky windshield!
Drive to a touchless car wash with your rug pulled back. easy to find leaks, and track them.
Hey matt, my passenger side is soaked but no antifreeze smell or seeet smell, but i do have a buzzing noise coming from under the dash never delt with a heater/ hvac leak before any ideas? Thanks man
buzzing? maybe you have a beehive in there! No, I've never heard that one before, check out this video: ua-cam.com/video/Hd-DFhOAlKk/v-deo.html
thank you i found this my jeeps been driving me nuts ,,,i need to get the tube
My Kia Sportage 2009 driver side floor is wet . How to identify and resolve the problem .
What year is that heater/ac box?
I have a ZJ and it is indeed from when AC is on. I have a ZJ unfortunately and so the tube through the firewall is blocked. Is there way to just create a better seal on the passenger side floorboard?
Do you know what year's the H-Box doesn't have to be removed or what year's is easiest to repair???
Mine leaks when it rains and when I have my ac on. Mine is a 96
can my evaporation core be leaking freon? I have an 02 wrangler tj and I can't find the freon leak. I added dye to the ac system and I can't find the leak. I was told the leak can be the evaporation core or the heater core. what do you think?
yes it can. not the heater core though, thats full of antifreeze.
Still tracking this problem on my 2001 xj. After hours of trying to locate the leak I’ve determined a few things: it’s obviously from rain, it leaks down the heater box onto the passenger floor, and I’m almost fucking certain its leaking thru the seal around air intake under the cowl, but that is unreachable. I’m replacing my wiper bushings soon so while that is out I’m going to see if I can reach the air intake under the cowl and silicone seal around that, and if that doesn’t work I might just say fuck it lol...
Hey, not sure if you got my last comment; I was logged into the wrong account when I originally posted. I was wondering if you knew what the name for the door/vent that you described to function as a recirculation door/vent of some sort. I accidentally broke the plastic lever that hooks up the small motor to it, & I haven't found anything on what it is called or where to get a new one. I'm starting to think I may have to try my luck at a junk yard, which means pulling some more HVAC boxes lol yaayyyyy 🤯
I forgot to add, it is the door/vent that is located in front of the fan
hey man
My drain didn't have a tube on it could that be the issue
Never mind I asked while watching and you eventually answered my question right on the head
My passenger footwell is filling up during intense rain. Has shorted my radio. Would love to know where it's coming from!!!!??? How to figure it out?
Probably the windshield, try searching a bit more, I have a video on that.
if i dont care about A/C could i totally get rid of that thing infront of you ? or would i run in to problems without it ?
+Alexander Barrera if you don't care about heat either then yes.
you could put some heavy shit under the dash with that thing gone...hell ya
thank you
I have a 2003 wrangler. Every time it rained water would leak into the passenger side. It would be one to two inches deep.
I found that the problem was caused by a clogged drain under the cowl (the panel below the windshield). There is a drain in the tray below the cowl that drains water from the tray to the outside under the car behind the motor. Also under the cowl is the air inlet box for the fan. So when that drain gets plugged, water fills up in the tray and enters the fan air inlet and drains onto the passenger side floor. The fix is to remove the cowl (about seven screws) and clean the tray and drain with a shopvac. Flush with water. If the drain is still plugged, run a stiff wire down the drain line while flushing with a garden hose. Easy. Remove the rubber hood seal in order to reseat the cowl back in place. Then push the seal back in place.
Did you ever find out what was going on?
all my glass is out, its real wet when I was it...lol
Great video but that hiss from the audio is driving me insane!
+John & Christina not sure what that is, I didn't change anything other than the location.
Wet floor? Hell... I thought it was just from all the spilt beer...
+Dwayne
Willing to bet that the only thing this guy drinks, comes with an umbrella in the glass.
From wiper motor to passenger fender clear the passage yall talk about it like its not a problem xjs had consistently
Shit. Antifreeze comes out of that drain on my cherokee😂😂
Antifreeze really stinks. If you can't tell see a Doctor...
cus my fucking windshields leaking!
Mine's wet from the homeless guy who slept in my seat and pee'd himself.
I will NEVER BUY another shit Mopar product again!!!!!!!!
