Downsides - you can’t open the sunroof; kind of a half assed fixed
Upside - no leaks

I would suggest using a black sealant. I used clear on my D2 and it started to get discolored so I ultimately resealed in black

If you like using the sunroofs (as I do), it's worth it to fix. Though tedious and a little time consuming cause you gotta all but remove the headliner, repairing the leak is not hard.

99% chance you just have to re-seal or replace the drain pieces. If broken, you can get them on eBay or I'm sure Will T has a bunch.

I sealed mine up with black 3M windshield sealant. I pulled the headliner and sealed them from both sides. But...make sure it’s your roofs leaking. The roof rails like to leak as well. It’s hard to tell which is the problem because they both fill the headliner with water when they leak.

I also sealed mine with black windshield sealant, which seems to work well. But I just noticed, as I drove through the car wash (now that the winter muck is mostly gone), that I have a big leak past the top seal of my tailgate door.

I sealed mine up after fighting with them forever. I also added the extra upper rear door seal from a d2.

Good Luck. Spent so much time and r&r on these sunroofs. Would really like to hear how someone keeps these working and not leaking in a super wet area like I live in.

In the 10 years ive owned this truck, ive never used them anyway. The only time id want to is when im off road but that will destroy them. So.....

Now, my floor boards are starting to rust and i just dont have the time to fix the sunroofs properly.

has anyone actually sealed theirs shut and stopped the leaks forever?

i used black silicone on my '96. front and back sunroofs and have had no leaks since. did this about six years ago.

I assume cleaning it with alcohol is a good idea

I was thinking about using stupid amounts of it so that it spills out after i close them shut. Then I can just use a razor to cut the excess

If the roofs work it's worth the fix IMO. Otherwise two words...Flex Seal (As Seen on TV!)

I know., but I just dont have the time to tear it all apart. I have a long to-do list on the rover before off road season starts and I never open them anyway.

If there is a less perminant quick fix, i would be open to it

I'd go w/ the spray or the brush on. You can tape off a nice strip all the way around the seam and do several coats. I did this to my cracked & weathered seals on my D90 and it came out rather nice. Also sealed up a leaking roof seam on a D2 with the same stuff. The tape is a bitch and doesn't hold up well to direct sunlight.

that would certainly do the trick.

i did not clean it with anything. just ran a nice, consistent bead all the way around, tooled it with my finger and called it a day.

I just pulled my headliner. It's the hardest part in this fix. My front sunroof would spill water into the headliner and then it would come out everywhere. Here's what I did and so far it's working great and my sunroofs work too.
1-pull head liner
2-cut the drain tube about halfway
3-drop the sunroof PAN (it's like 14 t-20 bolts plus the motor bolts (the motor will come too))
4-clean out the pan and all the junk
5-Silicone the inside joint between the pan and the drain thingy on the inside
6-silicone the outside joint of the drain and pan
7-reinstall the pan
8-silicone the pan
9-attach the motor
10-use a 10mm hose barb attachment thingy and zip tie the hoses to it
11-test
12-reinstall head liner
