Water is leaking on inside of cab and the drains in sunroof are clear

Try opening all your doors and look at the bottom of the doors for the slots that allow rain to drain from inside the doors. They are most likely blocked and water will leak over inside the car. Blow compressed air to clear sunroof drains from the top while the sunroof is open.

You may be able to clear debris out by using a long thin rod and pushing it into the openings on the front of the sunroof drain channels the pouring some water in to make sure it drains properly sometimes the drain pipes become disconnected inside the headliner but try clearing the obstruction first and see what happens.

The drain hoses typically run from the 4 corners of the pan around the sunroof. Usually the blockage is from the top side, so open the sunroof and clean from there. Some applications require that you drop the ceiling material for access.

weather stripping around glass, have to keep it soft with Vaseline or protectorate for rubber to keep seal, u may have to replace if its weathered, always a problem on sunroofs t tops etc..

check sunroof drain holes are not blocked.

your going to have to use a waterhose, start on top of truck wetting it down as you watch for leaks inside,thats how to pinpoint your leak. if you have a sunroof check drains, also check around wind sheild start there .good luck.

Carefully check the rubber gasket around the glass. Sometimes some debris (leaf, pine needles, etc) get caught between the seal and glass, allowing water to 'wick' inside. Not sure about the Jetta, but my Honda has a drain that sometimes plugs up with debris and goop, causing water to stay inside, sometimes dripping inside as u go around a corner. Best way to fix is to blow compressed air thru drain hole to clear. Last, check around sunroof and roof itself where they meet. Any damage to seal at roof, or torn rubber? If anything looks like it might leak, u can seal it w/ caulk. Check your home center for caulk that works on windows (exterior), it'll work on the car.

There are 4 drains on the sunroof (2 in each front corner, 2 in each rear corner).
If you want to check to see if they are clear, you can do this.

Get a squeeze bulb (about the size of a turkey baster) and squirt water down each drain, look for water draining out at the bottom of the car. For the rear drains, park the car on a slight uphill, and gently squeeze water down the drain trough on each side, here again, look for water draining out of the car.
If those ar clear, next step is to check the seal of the glass. The drains are only designed to take in a small amount of water, if there is too big of a gap between the panel and the body, it will over run the drain troughs (kind of like when the gutters on a house get stuff in them).

Finding water leaks is kind of a pain, but not if you take it a step at a time.
One thing to remember, water does not run uphill.

So to further water test it. Find a place where you can park it uphill or downhill, grab a flashlight, a friend and a hose.
Start at a low spot, and work your way around the sunroof (one person inside with the light, one outside with the hose). Just let the water run slowly, you don't want to use a nozzle or a spray.
Once you can see when the water starts leaking on the inside, you can narrow down the cause.

be very careful there are plastic clips i belive you must pull them either down or straight out get a putty knife behind there and look with a flashlight,,, also instead of remove the b piller you can buy some 14 Gage solid cooper wire and push it thru the drain to clear the blockage please rate -jeff
