JK Water Leak Diagnose & Repair Manual

Here is a manual regarding Jeep Wrangler (JK) water leaks. The diagnostic information is accurate, but the part #'s may not be valid for all model years,

JK Water Leak Diagnose & Repair Manual.pdf


I posted this manual in a few threads but thought it might be easier to find for those interested if it had it's own thread, hope it helps out...

Hmm. Trying to understand why this is not already in our sticky area... Done.

I took these 3 screen shots explaining how to fix the most common leak area. My passenger side leaks in the same area very bad. Seats, carpet, dash, ME. The water bounces off the door latch and soaks everything, I've already mentioned adjusting the door but haven't tried it yet. I do own a 07 so the seals could be worn as well.

I do have some experience with the elusive "under door leak" that seems to leak from under the floor mats. The week before I picked up my 2014 JK it had rained heavily for a week. sure enough, the driver's side floor was wet under the floor mat. Passenger side was completely dry. Now, i ordered my Jeep from the factory, so it wasn't like I could just pick another one off of the lot.
Having gone through this experience on my 2012 without satisfactory resolution, I was concerned. But, I also know the passenger side leak could have many causes, hence the "elusive" part. Driver's side seems to have a straight forward, easier resolution from what I've read over the past two years on these forum pages.

So, those of you with DRIVER'S side leaks, I recommend that you try this. I read about it on the forum and it has worked to COMPLETELY resolve my leak: Door Entry guards. But, you have to install them as illustrated in the picture below:

The trick is to install the entry guards over the front seam. Try it and let me know. Mine is completely bone dry now, even after heavy rain.

BTW some dealers will try to tell you that the entry guards caused your leak, but mine was leaking before guards were ever put on! Good luck!

Mine was bone dry (07) until I cleaned the plastic and rubber in and on my ride. Then we had a gully washer... got in a day later and noticed that water was ON my floor mat... mercy! I'll try the remedies mentioned here and get back with results. In the mean time... caution on what you clean the gaskets with it seems... I used a spray on over the counter cleaner. Wondering if it didn't mix well with the Bestop roof... made it shine though!

That manual is great. Left mine outside with the soft top on during an all night rainstorm this weekend and I think I might have several of these leaks. Both front seats, and all the carpets were soaked. Puddles under all the seats and all floorboards. The corners of the soft top had leaked from time to time in the past, but nothing like this. I do take my doors off a lot, so they may need to be adjusted.

I've also seen people refer to some kind of conditioner you can use on the a-pillar foam gaskets to restore them somewhat. Has anyone had good or bad experiences with those products? Any recommendations?

Question: does front and rear water spray work. There is only one water tank for Jeeps, so the water line for the rear runs thru the Fire Wall, down past the Driver Kick Panel to the rear of Jeep. And there is a disconnect that can come loose at the kick panel.

My problem is with the front passenger side. After any noticeable rain there could be as much as an inch of standing water. It has been to the jeep dealer twice and is going back again today. So far they have replaced the seal, which I assume is the seal where the soft top attaches to the windshield. The water leak diagnosis and repair manual referred to in #1 suggests that the source of the leak might not have anything to do with the seals around the door and windshield, but instead the source of the leak could be either the Rear Wheel Flare Holes or the Cowl Side Panel, particularly since it doesn't appear as if water is coming down the front slope of the passenger side floor.

Any thoughts anyone might have that I could share with the service tech would be greatly appreciated. Thank you.

OBruce

I have the same leak as you. Mine is going to the dealer tomorrow for the 3rd time to repair the same leak. I'll keep you posted what they find.

I just spent $600 at the dealer to repair leaks on my JK, and the drivers side still pours in. Frustrating.

Doesn't rain much where I live, but this issue really bothers me. My Hard Rock will be here soon and I will be spending a lot of money to buy my first Wrangler, it doesn't please me to know there are leak issues with this line of vehicles. I don't understand why after many years of production and apparently leaking, it can't finally be fixed from the factory. This seems insane to me.

I know how you feel. My Wrangler is still leaking after 4 visits to the dealer. They have replaced seals and the gaskets around the doors. What concerns me is that it doesn't appear to me, at least, that they have spent any time looking at the repair manual even though we have brought it to their attention several times. It is back in the shop again and this time it has the attention of the dealership's owner. If it still leaks after this trip I am planning to change out the soft top and put the hard top back on. Will try to keep the forum posted on how I make out.

Regards,
Bruce

Sounds like I'm in a similar same boat. I left my new 2014 JK out in the driveway last night for its first sustained rain exposure. When I went to check this morning, I found about a 1/4 cup of water pooled on the passenger slush mat. I could not get a sense of where the flow came in. None of the carpet in the area (or in the back) felt wet, and the plastic and metal had plenty of time to dry off. The JK is still outside and it's a wet day, so I'll check again later.

On the plus side, the MOPAR slush mats did their job!

An update to my leaking Wrangler. I went and paid about $45 for the seal kit (mentioned above) from the dealer. Reg auto shops had nothing to use. No instructions and weird looking shape on several. But I cleaned off the piece that had "rolled up" some on the leading edge of the driver's door.
I cut ( with a knife) the patch that had some foam look to it.
The leak slowed down a lot yet still leaked.
I then looked at where I thought water was passing at the harder foam next to area I had already addressed. A straight piece this time. In three weeks no leakage!
That second piece of foam was difficult to get the paper tape off to apply. But I did get to a piece that the paper came off quickly and clean. I just applied the new over the area of the larger foam piece.
I carry the rest of the small kit in the glove box. It came with a small baggy to keep the extras secure.
After seeing how much others here have spent on the sealing from dealerships, I'd suggest to everyone to get the kit and try it yourself. It is not complicated and will save a lot of time, frustration and money to try this yourselves. Good luck and stay dry.

Researching door seals I saw more then a few superseding part numbers.
My passenger side leaked bad. A Constant stream of water poured in, bouncing off the door latch and soaking everything. I bought and installed the new seal yesterday, it rained HARD last night, and there was only a drop or two on the door. The new designed door seal did the trick

Good morning. As promised here is an update on my leak situation. This time the Service Manager got personally involved and he assigned one of his best technicians. The tech pulled out the front passenger seat, took up all the carpet (front and back) on the passenger side and then water tested the jeep. The source of the leak was where the door seal/weatherstripping came in contact with the soft cover frame. The water was coming down the frame that separates the front and back doors, along the floor and emptied out into the floor board depression in front of the passenger seat. Although the earlier attempts to fix the leak had included new sealer around the seal/weatherstripping it wasn't enough. New seal/weatherstripping has been installed around the front door and the dealer is waiting for the "part" do do the same around the rear passenger door and then will water test before putting everything back again. The problem area was -when looking at the door from the outside- in the upper left hand corner of the seal where it meets the upper left hand corner of the door frame. Three additional comments. First, the problem is associated with the soft top and the soft top frame. Apparently, we would not have had the leak if the hard top was installed. Second, the dealership said that there has been an increasing number of leak issues in the last 3 years or so. And, lastly, the seal/weatherstripping is not covered under warranty.

Oh, there is one other thing. The technician working on the leak did pull the back bumper per the manual referenced above to confirm that that issue was not the source of the leak.

Regards,
Bruce

Could you please elaborate that? Even if I still had factory warranty ?

Not sure how much more there is to elaborate on. I have an extended bumper to bumper warranty from Chrysler/Jeep. The dealer checked with Jeep and Jeep said that the seals/weatherstripping around the doors is not a warranty item. Put another way, I have to pay for the labor and parts to 1. find the source of the leak, and 2. to replace the seals. And, as suggested on another post, it is an expensive proposition. I hope that helps.

Bruce

I experienced the same. Leaked bad with the soft top from the same area. 0 leaks with the hard top. The front door seal (assuming it's the same 2/4 door ? Cost $100 Depending on the year of your jeep, there maybe a new part number. like said in my previous comment, replacing the seal fixed my leak.
Labor ? 5 minutes. Pull off old/install new. Pretty straightforward.

Weatherstriping/Seals are most definitly included in all 'Manufacturer 3yr/36k' warranties.

'Extended Warranties' are nothing more than 'insurance policies' provided by others (usually Banks/Underwriters, ie-GMAC, etc..), they are NOT issued from vehicle manufacturers themselves.

As such, just like any insurance policy, you only have the protections you both agree to via the contract you sign..

What did you agree to?? (did you even read the contract?)

Water under floor matt

Hi All!
I'm pretty sure I have condition #4 on page 20 "Scuff trim foam missing". Found a broken plastic plug stem and a round piece of foam on the drivers side (where my leak is). How can I take this piece of trim off to inspect it without possibly breaking it more (if that is the case)?

Thanks

Recently bought a 07 jk soft top 4d. Removed doors and top saw flattened foam seals. Replaced all foam seals installed new door hinge bushings. Before all foam was replaced the carpet LF, and all REAR seat carpeting was soaked. Removed drains sun dried all carpet disinfected and dried floor boards. Water tested after foam was replaced and still leaking from b-pillars or the framing between front and rear doors on both sides. Headed to the dealer tomorrow 10-09. Any ideas so I don't get screwed??

I've noticed that if I leave Bottled Soapy Water or Packaged Toilet Paper on the floor or under seat I will find water or condensation. ALOT OF CONDENSATION!
