When i turn left water comes pouring into my front passenger floorboard under the glove box. what does this mean?

its most likely a sunroof drain. either its clogged or broken

You need to find the conduits for rain - one of them has a leak in it probably from corrosion. Try to locate just where the water is getting in and see if you can use a sealer to stop the water from getting in.

I would remove the glove box and anything else in the way and look for the source when hosing down the car.

This is a simple fix for water leaking from sunroof causing water buildup on your front floorboards. Most important thing is do not take your vehicle to a GM dealership or anywhere else and spend $400!!!!

This fix is easy and permanent and you can easily do it yourself!!

STEPS:

THE TWO DRAINS ON THE FRONT LEFT SIDE OF YOUR SUNROOF AND THE FRONT RIGHT SIDE ARE WHAT CARRY WATER DOWN THROUGH YOUR A&B PILLARS BEHIND THE DASH AND THEN OUT THROUGH THE FIREWALL. THESE STRAINS BECOME STUCK WITH LEAVES AND WHATEVER ELSE CAN FIT IN THE HOLE. FORGET ABOUT COMPRESSED AIR BLOWN DOWN THROUGH THE HOLES FROM THE SUNROOF THIS WILL ONLY CAUSE WHATEVER ELSE GUNK TO GET BLOCKED!!

THIS IS A VERY VERY EASY FIX AND SHOULD HAVE BEEN A RECALL ON GM PRODUCTS. IT CERTAINLY HAPPENED TO MY 2008 H3.


Okay the first step is to grab a flashlight lean backwards on your floorboard and look up behind the brake and acceleration pedals about 1 and 1/2 to 2 ft at your firewall. You can easily reach this with your arm. Look carefully and you will see a drain hose which is attached to a black rubber grommet that goes through the firewall. It is this grommet that is causing the problem!!

Detach the hose from The grommet by simply pulling it away from it. Don't worry about any water that drains from it.

Next, wiggle that black grommet back and forth while pulling and it will easily detach from the firewall. Now grab that sucker and get out from that awkward position so you can do this simple fix.

If you look through it you will see that there are three four or five rubber flaps which are inside of the grommet. I guess GM decided that it needed some filter for other ridiculous way to block debris in a hose that should be wide open, don't ask me why.

Now the easy part is to grab a drill and drill bit or whatever device you can come up with and get a drill that will fit rather tightly into the grommet and proceed to drill back and forth making sure to only clear out those rubber flaps. Remember, the rubber flaps are your enemy and the sole cause of your problem.

Once you have done this you will now get down on your back in your floorboard in that contorted position with your flashlight. You need to reinsert that grommet the same way you pulled it out. Just wiggle it back and forth while putting pressure until it pops into the firewall. Next, attached the hose and press it firmly into the grommet.

You have now fixed your drain issue, at least for the driver side drain sunroof. To test open sunroof and get a glass of water and proceed to pour it into the metal pan which is meant to hold water before draining. Get out of the car and you will see the water easily draining out from the side of the front left tire!

As a side note, just clearing this front left drain will drain 90% of the water from your sunroof or at least prevent any water from ending up in your car and covering your floorboard.

Now if you need to do the right side it is exactly the same as the left however, you cannot lay on the passenger side floorboard and access the grommet easily. This grommet for the passenger drain is located just behind the glove box. If you are comfortable removing the right side panel of the glove box then you will see that grommet and pull that sucker out and do the previous steps.

Personally, I was not comfortable removing the part necessary at the glove box to access the grommet so I took my car over to the friendly guys at my lube and tire shop who were more than happy to remove the glove box. I had brought my drill and bit with me and simply pulled The grommet out drilled it out and stuck it back in. The guys popped the piece back onto the glove box and I was good to go. I think I paid 10 bucks.

It is terrible that some people have been absolutely ripped off at the dealership and sometimes charge $300 to $400 or even more to do exactly what I just discussed..

I know this post is old but I hope that I can help at least one person that runs across this post. Good luck on that drain and have a wonderful day!

Your drain hose is clogged. If you park under trees, debris can get in there. Once the hose is clogged, the water has to go somewhere, so it goes onto the passenger-side floorboard because that's where the evaporator is (under/behind the glove box).

Is it coolant or water? If its coolant could be leaking heater core. If it is water chances are its coming out of the heater box because the drain for the water that pours on the cowl under the wipers is clogged and it is pooling up and going into your cabin filter or fresh air intake for the cabin. Take off the wipers and cowl, clean.

Check under the hood along the firewall, below the windshield around ac evap. and drain area. This is a common place for water to enter and flow by various means (duct system) to passenger rear floorboard as well as slight passenger side front...but usually noticed in passenger rear floorboard.

Check the seal around your interior air filter. The seal can come off at one corner and allow water to run down the firewall and into the passenger side.

My 06 was leaking during rain also. It turned out to be the sunroof. There are two drain tubes in the front of the sunroof that run the water down the corners to the ground and two drain tubes that drain water out the back corners. The water would seep around the glass, which is expected, but both of the tubes on the front of mine were plugged, and the water would overflow behind the dash and fill my floorboards. If my H3 was leaning to the left during a storm then the drivers side would be full of water. If leaning right, then the passenger side. I had to open sunroof and blow compressed air into the drain holes to clear them, but be careful, too much air will separate tubes from sunroof and then you will have to remove the inside paneling around sunroof to get to tubes and reconnect. You may only have one side plugged. you can test it by opening sunroof and pour a little water in the small catch pan in the front of the sunroof and see if it drains as expected (to the ground under the firewall on left AND right side). You can see the holes in each corner of catch pan to drain the water. Plug one with your finger, then the other to find the plugged side. Good luck!! Hope this helps!!
