Tip & How-To about 2010 Cadillac SRX

Sun Roof drain line leaking all over front floor board of car.

My sunroof drain line was leaking onto the floor in front. Pulled off interior A pillar (post between the side window and windshield) to expose the drain line. Using a flash light from outside the car, shining it down at where the windshield meets the dash, you can see where the drain line goes down into the fire wall of the car, or should I say does not go down into the firewall-if yours is not attached, like mine was. Mine was just laying inside the dash area, not attached at all. I made a tool to push it back into place. (a long tent stake worked well for this, after I put a slight bend in it in the middle). It took some doing, about 20-30 minutes of working at it and smaller hands to fit in a very tight place, but since I am a girl (yes, guys, we girls know how to work on cars too :), it wasn't as hard ). But now, problem solved. I had researched how to do all of this on the internet. Scariest part was pulling off the interior trim from the pillar, but once you do, you can clearly see the black tube drain line and figure out where it leads. If I can do it, you can do it. Good luck

why does drivers side floor stay wet


You don't way what type of vehicle you are driving. I will assume it has a sun or moon roof. Most of these have drain lines that run down inside the driver's side door pillar and exit through the floor pan onto the ground. Over time, these drain hoses dry out and shrink, often retracting into the drivers side kick panel. Then, all the rain water that drains from the sunroof will leak out onto the drivers side floor. If that is the case, you will need to remove the drivers side kick panel and repair or replace the drain line and reroute it through the exit hole in the floor pan.

Water leak in my range rover on driver side floor had drain unstop from sunroof what else could it be


You unclogged the sunroof drain line - that is good. Are you sure that the line didn't pull up thru the floorboard. Many vehicles run the drain line down the drives side window pillar and out thru the floorboard. If the hose shrinks with age (as some do), they can pull up into the cabin and leak on the floor.

20006 saturn ion water in floor board


The drains are in the wheel wells. You have to remove the plastic panel in the wheel well. Pour some water in the sunroof drain area you'll see it come out a little rubber nipple. Take a razor and cut off a little of the end of the nipple so water flows easily out. They are closed and the water pressure isn't enough to open fully and the water backs up and leaks inside.

I've got a 2006 Saturn Vue that keeps getting water in the front, under the floor mats. It appears to be coming from the center underneath and behind the instrument cluster/center console. Could this be from sunroof drains or does it sound like a windshield problem. Where do I find the ends of the sunroof drains? Any help would be greatly appreciated. Thanks!


The most common source of water on the floor is a plugged a/c evaporator case drain hose. This drain is generally located down low on the engine side of the firewall at the passenger side and is usually a small short open ended hose that points down. Debris and bugs will clog this hose which makes the water that condenses on the evaporator [whenever the a/c is on] overflow and leak out of the heater/air conditioning housing and onto the floor. If it hasn't rained for some time yet you are still getting water on the floor I would bet on this hose being plugged. A puff of compressed air is enough to clean most of them out. Most sunroofs have one or two small drain holes that allow water to run down through the door pillars and onto the ground. If you pour a small amount of water around the top edges of the sunroof when it is closed you should soon see water dripping onto the ground under the outer edge of the vehicle. A few sunroofs just rely on tight weather stripping to keep the water out but those usually drip water on the driver or passenger if they are leaking. I see a lot of leaky windshields but again, it has to be raining for water to get on the floor from them.

water leak on fwd passenger side after every rain storm


If your car has a sunroof, there are drains from the front corners of the sunroof, and they drain down the sides of the windshield pillars, and then empty out on the ground.

What I would do is open the surnroof, and pour water into the front corners, and then oobserve where the water drains out. If you have a difference in water drainage between the left and the right sides, I would think that you may have loose sunroof drain. They commonly come loose at the sunroof corners. This will allow the water to pass down the windshield pillar, and onto the floor.

Also, I would check the condensate drain tube for blockage. Pull back the carpet, under the glove box, and fins a black hose that pokes thru the firewall. Pull it out, and see if it is blocked internally. If this tube is clogged, water will build up in the heater box, as the black tube is the drain for the heater box.

One of the two above solutions will cure your problem. I see both quite often.

Thanks for choosing FixYa for assistance.
