Need help with water leak on driver side from Sun Roof.

Saw some water leaking out of the screw covers on the driver side handle. So I figured it was due to the bad design of the sun roof drain with the blue hose. I took out the plug from the floorboard to do the quick fix I saw on Youtube (cutting the opening at the bottom for easier drainage) but whoever owned the Jeep before me has already done this. So I am not sure why it is leaking. Only thing I can think of is whoever did the fix maybe pulled the blue hose causing it to pull from its position up by the sun roof...but wouldn't this cause water to leak onto the dash? Because its not doing that. Other than that only thing I can think of is a hole in the hose.

@Dyson350 ; Your water leak is not necessarily the result of a clogged sunroof drain tube.

Do you have anything mounted on the roof that was not installed by the factory?

A light bar or anything of that nature?

It could also be your factory roof rail bolts/screws are rusting out, allowing water to get in - or you could have a bad door seal or a door out of alignment.

You have to figure out definitively where the origin of your leak is - and it can be a real PIA trying to isolate the cause.

Commanders - particularly those with sunroofs are pretty notorious for having water leaks - the sunroof drains are a common cause, but my point is, they are not the only cause. Could also be that the sunroof seal/gasket itself, needs to be replaced.

Until you definitively isolate the cause, you can only speculate - but you can't just assume it's the sunroof drain tubes, particularly in your case - where it seems like that issue has already been addressed.

There can be other causes as I mentioned above - any of which would produce the same, or very similar symptoms, with water leaking out of the driver's side front interior grab handle over the dashboard.

You may have to go out in your driveway with a hose and just run water on the roof continuously and try to track the source of the leak down that way.

What makes me think its not something in the roof like a seal or bolt is there is no signs of water on the ceiling of the interior. I'm going to take it to a shop and also does windshields and have them check it out. I am not convinced its not a seal problem on the corner of the windshield. Whatever it is, I hope it is a easy fix.

Will do, this problem really have me stressed out and want it fixed asap. So many potential issues can stem from this, damaged electronic, water damage on floorboard, rust, ect...no idea how I am going to wet the water out of the foam under the carpet.

That's totally understandable and I'd have the same exact sense of urgency if I was in your position.

Assuming it doesnt leak more, all it was was the drain hose came loose at the top. $45 fix

Yeah, main thing now is the water on the floorboard. Its all cleaned up but the foam is ever so slightly damp. I am hoping it will be dry enough to not be an issue at this point.

This might sound silly, but, I would try just blowing it dry with a hair dryer for a little while.
