H3 Hummer leaking water into cab.


My 06 H3 was leaking when it rained. It turned out to be the sunroof. There are two drain tubes in thefront of the sunroof that run the water down the corners to the groundand two drain tubes that drain water out the back corners. The waterwould seep around the glass, which is expected, but both of the tubeson the front of mine were plugged, and the water would overflow behindthe dash and fill my floorboards. If my H3 was leaning to the leftduring a storm then the drivers side would be full of water. If leaningright, then the passenger side. I had to open sunroof and blowcompressed air into the drain holes to clear them, but be careful, toomuch pressure will separate tubes from sunroof and then you will have toremove the inside paneling around sunroof to get to tubes andreconnect. You may only have one side plugged. you can test it byopening sunroof and pour a little water in the small catch pan in thefront of the sunroof and see if it drains as expected (to the groundunder the firewall2_bing.gifon left AND right side). You can see the holes in each corner of catchpan to drain the water. Plug one with your finger, then the other tofind the plugged side. Good luck!! Hope this helps!!

Sunroof needs adjustment over drivers seat ..leaks


Many fords have some minor adjustments of the roof, the brackets that support the Sunroof or power sunroof have very small Hex nuts you can loosen and shift the sunroof around, if its leaking it could be some other problem such as the drain tubes, there is usually 2 to 4 drains one on each corner that water drains down a tube through each door pillar, check the tube ports in the sunroof catch basin, they could be clogged with old leaves or dirt, run compressed air through each tube and verify at the other end its working.

How does a sunroof drain


It depends on the sunroof (aftermarket or OEM) it also depends on the particular year, make and model of the vehicle we are talking about. Some sunroofs are sealed in such a fashion that they do not need drains. Others have rain channels and tubing that runs down either the "B" pillars or the "C" pillars in the vehicle. On the ones that have plastic drain tubes, you can usually see the ends of the tubes sticking out under the vehicle

I have a 2003 honda civic ex 2 door. I have a rain leak on the drivers side by the gas/trunk lever. I keep reading it most likely is the sunroof drain. Where is the sunroof drain and how do I get to it to...


It may not be clogged. I believe the sunroof drains run down
the roof pillars and then connect to another hose which exits
through the body behind front fender. Unfortunately the hoses
connect inside the car. Then again this might not be the source
of your leak and water leaks are hard to address. Your dealer
might be your best bet. If the sunroof drains are clogged, Honda
knows entry and exit and they have to be unclogged with compressed
air.

Where do the sunroof drain tubes exit this vehicle?


There are a total of four drains, two front, two rear. The front drains empty out inside of each front door jam. The rear drains empty out inside of the rear bumper. If you drain holes are clogged, use an air compressor to unclog not other as you may either break the drain tube or wack it out of place. I believe there is a technical service bulletin for Grand Prix sunroof mdels 1998-2005, In your sunroof leaks, contact your dealer for more info. Take care and hopes this works for you.

How can I unclug my sunroof?


The best item is weedeater (weedwhacker or whatever you call it) nylon. It is thick enough to push blockage out and flexible to handle any bends. Also check the exit of the drain tube (behind a cover near the front wheel on my GTV6) as an accumulation of mud will prevent the gutter from draining out.

2001 Volvo V70 with sun roof...car sitting in heavy rain..return to car both front drivers side and passenger side footwells were full of water. What could cause this..no the windows were not open or the...


Not familiar with the Volvo, but many cars (Toyota, Lexus, Acura, Honda, etc.) have drain holes at the corners of the sun roof assembly. These holes allow water that gets past the sunroof gasket to drain through tubes that carry the water to the bottom of the car, where it exits the car.

These drain holes are prone to clogging. If the Volvo setup is like those cars mentioned, you can see the front drain holes by opening the sunroof and looking closely at the two front corners of the assembly that holds the sunroof. I have used plastic weedeater line to open up these lines. Compressed air can also be used.
