Can't fix anything till you find out where the leak is

Remove whatever trim you have to,to see the water
entering

I'm assuming the vehicle has a sunroof, if so you'll need to be sure there are no obstructions like leaves or small sticks keeping the sunroof from completely closing. If the sunroof is closing properly it may be time to replace the weather stripping seal around the sunroof to get the leak stopped. Please rate this answer, thanks.

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.

I ad this problem several times. You can take a long flexable piece of plastic. I use a item you can buy at the fabric store for a couple dollars to thread string through garments. In the front of the sunroof with it open there is a small tube like hole that angles toward the windshield (the piese between windshield and front windows). Put the plastic in those tubes and feed it in as far as you can, this will clear the opening and your problem should be fixed.

hopefully is not after market sunroof, if it is, your in trouble. factory sunroof replace rubber seal is the only way to fix the problems

i have a leaking sunroof.so how can i fix it without it costing an arm and a leg

Betta Windsrceens Stockport have been repairing sunroofs for 30 years. What i will tell you is both the mk1 and mk2 clios have a problem with the sunroofs.
The sunroof needs to be taken out cleaned damming seal on frame removed and fitted back with silicone sealer excess sealer clean of with white sprite no need to remove head lineing if fitted with 10 mm bolts use a ratchet spanner. Mk1 clios also leak from the arial remove and reseal. And mk1 & mk2 have a problem with the bulk head filling up with water. Open bonnet on the back of the bulk head is a hose about 6 inches long which gets blocked un block and the water can drain like it did the day the car left the factory. bettabob
