So I had a windshield installed awhile back and it cracked due to the windshield being bad. Once they replaced it after a few weeks I noticed water on the inside of the Jeep on the dash along with water coming from the passenger side A Pillar. I also noticed the headliner between the windshield and the front of the sunroof would get wet as well. I tested the drain tubes and they seem to be working. I took the Jeep back to the place that installed it and he put sealant around the windshield and tried to figure out where it was coming from but said he couldn't find it.

I have no idea whats the problem. I poured cups of water on the windshield and sunroof to see if I could make it leak but I couldn't. It seems to only happen when I drive (from what I can tell atm) like the water collects then it gets wet wherever the momentum takes the water. No other spots on the interior are wet either so I dont think it would be coming from anywhere further back on the Jeep like the skylights in the rear .

Water coming from the PS A pillar and wet on the front of the headliner are generally the sign of clogged sunroof drains. You said that they seem to be fine. I would clean them out anyway, might just be a slower then needed drain. I have to clean mine twice a year, I live in a conifer forest, and we get 54" of rain fall a year. Lots of needles and debris. I've rigged up an air nozzle with a tube, and put my compressor's pressure regulator down to about 10 psi.

I will give it a shot, but like I said. I have poured a full cup of water into the tray directly over the hole and I didn't see any kind of back up other than the fact I'm pouring lots of water in a small area. Also like happened today. there was lots of water on the dash right in the center of the Jeep. It rained but I don't think it rained enough to cause water to reach all the way to the center of the tray and spill over into the headliner, especially if I just poured lots of water and didn't notice any issues.

If it was me, I'd take it back to the guys who replaced your windshield and say "Hey, WTF?" I didn't have this problem before you replaced the windshield.....

That's what I have been doing. This will be the 2nd time Ive had it in there. Its about to the point Im gonna say look if you cant fix it then I need to take it to someone else, BUT if they tell me its the windshield I am having the bill sent to you.

Do you know if they sealed the top of the the windshield? If not you may get a whistle at high speeds and also water leaks

Also check the cowl screen seal around the lower portion of the windshield. The previous owner had the one on my vehicle replaced and they destroyed this seal and had uneven sealant in this area that I had to fix. I also ran another bead at the top of the windshield just to be sure.

I am still trying to find the problem. They used a hose on the windshield and did not get any leaks. I took it to another shop to look at the sunroof and they cleaned the seals and adjusted the sunroof along with look at the drain hoses and also let water pour across it and they said no leaks.

Last night is rained hard and when I got in the Jeep there was a big puddle on the dash and the headliner from the front of the sunroof to the windshield was wet as well. There is also no wet headliner anywhere else inside the Jeep. Considering the Jeep was sitting and not moving yet the wet headliner reach as far back as the sunroof I am pretty sure that takes the windshield out of the equation. I have no idea where the hell the leak is coming from. It makes 0 sense.

@Dyson350;

If it was my XK, I'd just have the entire sunroof and seals replaced just to take that possibility 100% out of the equation as a possible cause; Short of that, assuming that your front windshield & sunroof seals & drains are good, your next most likely cause is your factory roof rails; That is assuming you have nothing else mounted on the roof or bolted to the roof. I'm guessing each roof rail has 4 or 5 bolts mounting it to the roof.

When the screws/bolts in the roofs rails start to rust the seal they have against the roof will eventually lose it's water-tight integrity and allow water to seep in; this water will typically travel toward your front windshield in between headliner & the roof ; Gravity along with the curvature of the roof always seems to have it travel that way, and eventually it funnels into your A-pillars and you'll see little drops coming out from where the screw hole covers on the grab handle; Or the water could just pool up right there, where your headliner meets the front windshield; Usually it eventually finds its way into the A-Pillars though. It could be on the driver's side or the passengers side, depending on which roof rail has the rusted/corroded bolt or bolts.

Visually inspect your factory roof rails thoroughly for rust & corrosion; if you see any screws/bolts that are rusted or corroded, pull the roof-rail off and replace those screws/bolts and seal the holes with outdoor/all-weather silicone when you tighten them down.

I would also take a good look at your doors, and doors seals and make sure your doors are properly aligned and that your door seals are in tact and in good shape, bad door seals and/or doors that are out of alignment can also allow water to leak in a travel along the roof toward your front windshield.

Yeah the rails were something I was wondering about, that or the skylights in the back.. But if this were the case and gravity was causing the water to travel towards the windshield I don't understand how the liner in the front of the sunroof would be wet. The water would have to wrap around the sunroof and travel back to the center of the vehicle to get the liner wet were its at atm.

The first thing I said was, I'd replace the sunroof and the seals if it was me.

Also you failed to mention that this is not the first water leak issue that you've had;

Since you've had prior sunroof/water leak issues before, it's probably time that you bite the bullet and replace the sunroof and the seals.

First leak was nothing more than a drain hose issue. And I would think if the seals were bad, when the shop ran water from a hose over it there would be a leak for sure. I'll just have to call them Monday and see. Hopefully its just the seals needing replaced but at this point I don't know. None of it really adds up.

I had similar sorts of issues on my 2007. I cleaned and cleared the drain tubes and did the modification of trimming the restrictive bottom end. After some advice on here (when nothing else had worked...) I had the sunroof seal replaced. I had already had a local body shop seal it up completely with silicon sealant and that stopped it so I was pretty sure of my source. What they said was that water was getting in in such a way that although the drain tubes were working, they were being overwhelmed and not coping. My headlining was wet all around the offside of the car (passenger side in the US I guess).

They replaced the seals and lined everything back up and since then, no more leaks. I kept it covered for a while but it has now been parked and driven in pretty torrential rain with no issues at all.

Well, you'll just have to systematically address ALL of the possibilities until you find the cause.

I wouldn't overlook the factory roof rails either. Just because in your mind's eye, it doesn't make sense to you - doesn't mean it can't be the cause. Water leaks can be tricky.

This is what I suspect is happening with him; sunroof seals/gaskets and the like don't last forever; If they are 11 or 12 years old, there is a real good chance it's time to replace them no matter how things may look from the outside.

The fact that he's had sunroof leaks before less than a year ago (clogged drain tubes or otherwise) makes me believe that's the case even moreso.

Hoping its just the seals. I took it back in today and will wait on what they say. I covered the sunroof with a tarp after I found there to be a leak and I didnt get any more water in it from what I noticed. Still so confused how if this is the case how could water from a hose not cause the seals to fail.

The volume of water coming from a hose does not come anywhere close to the volume of water that a good rain fall will produce.

When your common sense fails you, you have to start thinking outside of the box. Meaning you have to start looking at obscure, less obvious causes - not just what makes sense to you.

Like I said before, water leaks can be tricky - and deceiving.

Took the Jeep back to the shop and they were able to find the leak. Was coming from the back of the sunroof, running down the valley of the sunroof to the front of the vehicle which is why we only saw water between the windshield and front of the sunroof. Going to replace the seals and should be good to go.

That sounds like pretty good news; Glad they were able to track it down for you.
