I wouldn't go that extreme. Maybe reseal the windshield and make sure you apply sealant on the vertical parts of the glass too.

Only glass to rubber. It's been too rainy or frigid when I've been home to do metal to rubber.John, did you do gasket to metal too or just glass to gasket?
I have been led to this, while diagnosing AC/ Heater issues, that led me to leaking from sunroof or windshield.
If you have access to compressed air, here is a great way to find the windshield leak, in my opinion:
I found the leak using soapy water and airhose. It started bubbling where air could find its way through the leak, while I blew air from the inside of the windshield. Planning on sealing the whole thing now, with op's sealant.
If you're looking for info on sunroof leaks, there is a FAQ that goes through the whole process somewhere, you can search for, that was a huge help for me. I have clean drain hoses now, and watched as it poured freely out underneath the rig in all 4 corners (have to move to let gravity help see each one on its own, btw).
I don't know how the Jeeps are done, I just found this useful for actually confirming where a leak really was. I wanted to see if there was a way to confirm it was my windshield and/ or my sunroof. I am confident my sunroof drains are flowing, after a good cleaning, so wasn't sure if windshield seal was necessary. It is in my case, and I saw that it for sure was leaking in top driver side corner, right at the bend.So Cherokees don't have windshield gaskets? Is that a common thing? Looks like it sits in a bed of sealant that gets covered up with fancy chrome. I've never really paid attention to windshields before.
My 80 series Land-cruiser has rotted out the passenger floor due to a leak.
After trying a caulking gun loaded with silicone roof sealant (sikoflex) at least 3 times
- injecting it under the rubber glass side of the rubber seal and the body side it still leaks!
I have still traced water running down the door pillar area
- some at least from under the bottom/end of the roof lining trim that goes down the door pillar.
Since I have no sunroof and the roof gutter joints seem OK it must be the windscreen still ??! ;-/ ???? and some more !!!!
(I already have the dash completely out by the way - the carpet is completely out as are the seats too...)
I have noticed the passenger lower corner of the glass has some white color to it
- seems like the laminate has been discolored/damaged in this area.
- which I read on here is a sure sign of water leaking through the windscreen seal.
There is dampness/wet on the inside in this corner area too.
I really cant see how the silicone has failed to seal the screen - but apparently it has.
- The car is just sitting on the drive outside (not being used) - so that too eliminates some possibilities compared to a car being used.
Each time I wait till its dried out completely in the hot sun - seal it again - then check it the next time it rains.
The last time I shot some silicone round it I went well overboard smearing it over the edge of the rubber to the glass and to the body too.
- NOPE - still leaking!
I already have the scuttle panel off and that's been silicon-ed to the body under its lip and on top too.
Both front wings are completely removed inner and outer wings
- so I have a clear view of everything and there's no holes or anything that could account for water getting in
- and anyhow at least some of it has to be coming in from above the wind mirror level for the door pillar to be wet on the inside at that height.
All I can think is the windscreen is still leaking --- somehow.
So now I will have to clean all that silicone sealant off and try out some of this polyurethane sealant that firetruck41 has used.
Thank you firetruck41
I only just joined this site after finding the thread whilst searching for a remedy for my 80 series leaking each time it rains.
I am so impressed with the detail I have found and excellent pictures people have posted on this topic.
I will report back - when I can bring myself to remove all that silicone mess I have made and followed firetruck41's instructions.
Wish I had thought of masking both sides of the joint with tape as per the correct method ;-/
before smearing everything with silicone in a desperate attempt to just eliminate/trace the potential source of the leak.
Best wishes to all for 2016 from Australia.
Thanks again every one for this site.
I tried Googling the factory alarm location without success. Do you know the location for zlplocking it? Also, is there the possibility that an ECM, which controls the horn and locks, has shorted out when wet from rain? btw, the ceiling cover, A frame and interior windshield areas are dry in the rain. The sunroof, during the rain, is not showing any back-up from the drain holes. The front-passenger-side wet carpet is near the passenger seat. The windshield trim looks pretty tight (unable to lift it up) except for the area around the cowling at the bottom/front of the windshield. This trim piece feels like it is attached to the cowling and is not attached to the windshield at all. There are actually several areas which are gaps in the windshield trim. The trim is not one oval piece which follows the contour of the windshield. Is this normal for USA 100 series (I think everyone else is 80 series on this thread)?If you have an alarm on your car, sometime that can cause the horn to go off. Rain drops fall on it and short it out. Check that one too, maybe ziplock bag it. Reseal the windshield and clear the sunroof drains.
yeah, I keep finding myself on the 80s forums when looking at leaky stuff.You probably want to try the 100 section.
I am sure there are a few people here with both 80 and 100, but is unlikely to come here since this is a hidden issue for a 100 series in the leaky thread for 80's.
