Volkswagen Jetta GLS 2003

I am getting water when it rains. It seems to be only on the drivers side front and back floor. I see several comments or complaints in regards to this problem. I am Costa Rican we have lot of rain falling every day as a tropical forest country and I would like to know if you can help me with this kind of issue.

Best Regards,

    Thanks in advance. What do you think about sunroof?

    I have the same problem but on the passengers side. Last rainy season it did it also. I tore my car apart to dry everything and found there are plugs on the bottom of the floor boards which have popped up in the inside of the car leaving a hole about 2 inches wide for water to come in. I thought the water would drain through these. But i replaced them and now i have the same problem. I hope it is the sun roof this time?>

    I've just experienced the same problem with the passenger side of my Jetta (some water also collected on the center console right by where the stickshift is!). Not wanting to exacerbate the issue, I've not yet tried to run anything down through the sun roof drains other than some air (rather ineffectually, I suspect). If anyone has additional suggestions on how to ensure that the water drains externally rather than internally, I'd be much obliged! Thanks!

There are drains that go from the factory sunroof down the frame and come out in the door frame. If you open your front driver's door and look at the forward part of the door frame you will see what I am talking about. Make sure these drains aren't clogged. If you can find something stiff enough to force down the drain, but still flexible enough to go through all the turns and not poke through the tubing you can push out any gunk. With the sunroof open you should be able to see the holes around the edge of the sunroof frame. These drains are why there are fewer problems with the factory sunroof versus an aftermarket one. Even if some water gets through the seals it has a place to go. Other than that the door seals are really the only other place prone to leaking unless there is some hole in the floorboard. But that would be strange.

There is one more longshot place. In the front drivers side under the dash there are some holes to pass through wires to the engine bay. These holes have grommets that keep water out but if someone did some aftermarket work on the car they may have added wires here and not sealed everything up tight.

Since the water is on the drivers side only I'd start by taking a quick look at the door seals on that side. The driver's door is a good candidate for problems since it is used the most. Also, if the seals are bad you might be able to notice more road noise when driving. Goodluck.

The problem is most likely either the door seals or weather stripping. over time they become brittle because of heat and humidity. i would have that checked out chances are they need replacing.

    the weather stripping around sun roofs are notorious for leaking over time.

2003 jetta gls rumble in the front end

sounds like a gearbox bearing ,,,this sounds like a growling noise usually when accelerating although as the problem gets worse it can happen constantly ,,, wheel bearings can growl too but will give a constant noise regardless of acceleration ,,, you need to see to this quickly as the more you drive you will cause more damage and cost to you ,,,,bearings will fix it in the early stages but if more damage is done you could have to pay for new gears and shafts which is expensive
