Leaking system drainage sunroof how can i fixe?

Check to see that front drainage holes in the sunroof track are not clogged. They should be on either side of the sunroof. If clogged the water will back up toward the center and leak inside.

sometimes even when seals look ok,they are not.

If you don't have a sunroof, then your windshield is leaking. There are no other drainage tubes

If your vehicle has a sunroof, then check the sunroof drainage holes for blockage. Use an airline to blow down them and clear them of any debris.

Open up the sunroof and try to unclog the drainage. You will see this from the inside of the ML by opening the whole sunroof and stickin your hear thru. On the drivers side you will see a drainage whole similar to the passenger side. Mine did the same thing and unclogged it with a straw. [email protected]

How to Repair a Leaking Car Sunroof Repairing a leaky sunroof usually leads to discovering that the sunroof is not the culprit of the leak. Instead dirt and debris may be the likely culprits since they obstruct the drainage tubes or the drain channel that are part of the sunroof's water management system. Once these are obstructed, the water backs up and heads for the nearest escape, which may be to the interior of your car. The following instructions are to help you repair a leaking car sun roof.

1. 1)Use a non-abrasive cleaner with a soft cloth to clean the glass panel and the seal on the outside of the car.2)Open the sunroof after opening the vent shade. Allow the sunroof to open to the vent position but do not let it slide backwards.Wipe and clean the trough that is around the opening of the sunroof. 3)Use a wet cloth to remove any debris that may be preventing a tight seal between the trough and the sunroof's seal.Inspect the seal. 4)Look for any cracks in the seal. If you find any, you will need to replace the seal. Contact the car manufacturer or a repair shop to replace the seal.Check the drainage tubes.5) You can use a small cable or even a coat hanger to gently probe around for a few inches to see if there are any clogs or standing water in the tubes.6)Use a thin cable or coat hanger wire again to try to clear the drainage tubes if they are clogged. Make sure whatever you use does not have a sharp end and apply only a little pressure.7)Verify that any of the standing water in the drainage tubes went down by poking a dry thin cable or wire down an inch or and pulling the wire back out.8)Check that the clogs are completely gone in the drainage tubes by pouring a small amount of water into the tubes.

   How to Check a Sunroof for Leaks There's nothing nicer than a sunroof in your car, especially on a spring or summer day. Open the sunroof and enjoy the fresh breeze. But check a sunroof carefully for leaks before you buy a used car. It's just good business. 1)Open the sunroof to check for leaks when you are shopping for a used vehicle. First of all, make sure the sunroof opens smoothly and closes securely. A good, snug fit with no cracks or lop-sided setting is a good indication that it won't leak.2)Look carefully around the inside edges of the roof of the car where the sunroof opens. Check a sunroof for leaks by making sure there are no signs of rust or corroded metal around the opening edges. Of course, examine this area while the sunroof is open so that you see all areas on the sunroof opening's edges.3)Check the ceiling inside the vehicle when you check a sunroof for leaks. Look for signs of water stains around the inside ceiling lining of the car at the sunroof's site. Ceiling fabric at the site of the sunroof or around the area of the sunroof that looks spotted or has slight color variations may indicate a sunroof leak.4)See if the car's headliner (the ceiling fabric) is sagging. A leaking sunroof may cause water to run inside the headliner. Water buildup causes the headliner to sag over time.5)Examine the floor of the vehicle carefully when you check a sunroof for leaks. Damp carpet or a mildew smell may indicate a leaking sunroof. Also, look for water stains on seats where water may drip down from the sunroof. This will help.

If you have a sunroof then the problem is most likely a drainage problem with the sun roof. The drains are blocked and the water is running down into the car.

The under the dash thing is the only thing that worries me. That is usually the location where the heater core will leak to. Are you sure it is water and not coolant? Coolant gives off a sweet smell and when it's hot you know cause it stinks.

But my money is on a sunroof leak and drainage problem if you indeed have a sunroof.

Generally with the sun roof, If you open it and look in from above, If the drainage is blocked you will see excess water that wont go away. If there is no excess water then the chances of it being a blockage are minimal, its more likely to be a gap in the rubber seal allowing the water to seap through to the interior. If it is the seal, which i guess it is as they crack over time, then these are generally quite cheap from your local motor store.

What they meant by "they all leak" is that the sunroof seals around the glass are not meant to keep water from getting down in the sunroof, and tray and drains are there to drain the water that does get down in there. The problem most likely exists with your drainage tubes. They can either be clogged, or in my case with my 06 H3, the tubes were somehow disconnected and I had to drop down the roof panel to reconnect one.

AH! I had this problem. The drain spouts are in the rear of the car. When you open the hatchback, there's the panels, where the helper light is, you have to take this off to access the drain thing. It comes undone a lot in these cars.
