Sunroof leak where to start?

[bucko89]

I got in my truck the morning and found the passengers seat was wet the trim round the sunroof on that side felt damp. What would be the first place to look. I was thinking about wiping the seal and checking the condition is there any other things I should check?

Above the headliner, the moonroof assembly is pretty big (3' x 4' maybe?) and there's a gutter that surrounds the moonroof itself. At the corners of the gutters are drainholes with tubes attached. The drains often get clogged with dust that has gotten damp and turned to mud. leaves, or other debris.

As an aside, ALL moonroofs leak at least a little and that's why the gutter is there. While you're fixing this issue, I'd recommend servicing the entire assembly -- cleaning the tracks, gutter, drainholes, and lubricating the gears/cable/motor.

So this morning I got in the pass seat was dry but the floor under the dash was wet could this be the sunroof still?

It's possible. I believe the front two drain hoses run down through the A-pillars. If the passenger side isn't exiting in the correct location, you could see a wet spot there.

I have got the truck on level ground and it looks like the drain is blocked there is fine dust around it and if I put water in the drip tray it doesn't run out what is the best way to clean the line I have though about blowing it out but I don't want to damage the line as I'm sure it's only thin. I was thinking maybe try like 20psi and see if it removes anything. Also do any of you know where this drain exits' the truck?

So fare this seams to work.
I filled the gutter and let the water soak for 20min as ther was lots of dust and mud around the blocked hole then got a length of 14ga wire slide that threw the tube sevral times and it got easier but still did not drain as fast as the other side so I got some 1/4 Flexible hose slid that down and blew in to It then it got less restrictive. It took along time but is now free flows I went around the out side of the seal with some silicone grease to help it seal hopefully it works in the rain

Did you drop the headliner to do this or were you able to do it from the top of the vehicle?

[bucko89]

I was Abe to do it from the top with the sunroof open the cleaning I's probably quicker if you can remove the tube buy I'm Shute that is outweighed by the tine to remove the headliner

If you have a good air compressor you can blow air down the drain tubes. That usually clears them out as long as they aren't plugged solid.

I am having this same problem. My glove box is getting wet & staining the edge of my headliner. I opened my sunroof & looked from the top for the drain holes to blow them out but I couldn't find the drain holes. Are there 2 drain holes on each side? Can these drain holes be blown out from the bottom side? Any help would be appreciated!
