I noticed that my front hand grips on drivers and passenger side are dripping water when it rains out.
I RTV'd the marker lights on roof
I RTV'd the weatehr stripping around the door when it seems to be a little easy to pull at the front top corner
I filled the sunroof reservoir to which I thought I found the problem as it was not draining.
I took some weed whacker cord and jammed it in about 4-5 feet and then the water drained away fast

Now a good thunderstorm hit, I go running out to my H2 and jump in. Same problem

Am I missing something? Is there another weak spot that I need to take care of?

*I guess I need to recheck the reservoir draining speed again but....

 

OK, rain calmed down and I jumped back in. Handles still dripping. I opened sunroof and the reservoir is damp and empty.

 

Ok so this morning I continue my "sealing adventure"
I decided to take some RTV and put some more around the marker lights

Also to note: When I took off marker lights and looked down in the hole, I could see the headliner but it didnt look stained.

Also to note: I inspected the sunroof track (U channel) and I do see 1 hole on each side that show the head liner too. But the reservoir would have to be backed up and over flow in there.

Maybe there is a read reservoir and the rear tubes are clogged and during the rain it floods the U channel and leaks in?
*However my truck is parked on a level ground


Any thoughts/clues/suggestions/spells would be greatly appreciated

 

Today we had a light rain shower. Sure enough - dripping from both of the handles.

I can pretty much rule out the marker lights at this point. I mean they are RTV'd real good

Suspects are: Sunroof, U Channel in sunroof, windshield, roof rack tracks

Unless it is the sunroof seal - not the side where the sliding window is but the side(s) that favor the roof itself.

 

when mine came in the handles like that it was the corner marker lights, did you put a bead around hole that rubber bung fits into that the wires for the light run through? just another idea, sealed mine dry as a bone, I cleaned the area with rubbing alchohol first also followed the track where water flows and drains and removed a ton of crud, if you have to put a hose on one light at a time and or sunroof separate and see which area leaks

 

I did... I removed all marker lights and corner lights - smeared RTV on bottom of lights and in the hole. Placed it back on, ran more RTV around the edged and on the screw in the back too. It holds a puddle of water if I place my hand in front of it

 

Its the light rain that is confusing me now

 

well id wait for a dry day and do the hose test, one spot at a time till u find the leak at least you can eliminate one area at a time that way, stopping water is always a pain

 

ok - I ran the hose over the marker lights for 5 minutes. Which is way more of an amount than a light rain. Figure 4 gallons a minute - so 20 gallons,
Not a drip

Ran water down the roof rack tracks for about 5 minute - nothing
On the door seals too

I ran in on the sunroof then I looked at reservoir and it was holding water, AH HA...
I watched it and it slowly goes down

Now when I tested it I ran a cup of water in a bone dry tube. I am thinking I didnt pour enough in the tubes so it emptied the reservoir quick - like filling a tall thin glass of water

So I filled up reservoir up until it held water - took my weed whaker line and snaked it through until it hit something then I banged at it or chopped at it. I looked at front wheels and seen it dripping to is was draining . So I fired up my air compressor and connected the "rubber tip" option to it, jammed it in the sunroof holes (set it for 45 psi if that makes a diff) and blasted it in there.

Now when I fill up the reservoir, it drains like a toilet

Official test will be this afternoon and the rainstorm that hits us

 

Light rain for about 30 minutes - h2 is bone dry

I think problem is solved

I did order this so I can get to all areas in sunroof - may as well clean all tubes
