Hey all, we've been having intermittent water pooling inside of the footwells for both the driver and passenger sides over the past year after a good rain. We've had this problem before with another car and we know it's caused from the moonroof channels getting clogged and not draining properly when raining.

After trying to use an air compressor to blow out the lines and also using weed wacker string to snake out the lines, this still happened from time to time.

I finally broke down and took apart the glove box and the found the clog in the lines. Once removed, you can see a clear plastic hose that runs from the moonroof to the engine well. You can easily remove this hose and snake out the clog at this junction. Ours was pretty gunked up and we were able to clear it out fairly easily where it doesn't happen anymore. The driver's side was a bit more challenging as we didn't have much room to work but with a little effort, you can reach this component and clear it out as well.

While at it on the passenger side, I removed the blower fan assembly for the AC/Heat and removed a leaf that got stuck inside which was making some noise when it was on high.

Figured I'd share this info just in case someone else was having this same issue with water leaking, etc.

That's crazy... I didn't know the hoses clog so easily. Do you get a lot of tree droppings on your roof?

I'll keep an eye out, thanks for the post.

Yes, unfortunately, there are several trees on our block and there's a huge one right where we park our car. Tons of pollen, junk, etc.

This used to happen to our old car all the time so moving forward, I'll have to just check the lines every now and then.

You’re gonna kick yourself when I tell you an easy solution to these drain problems without undoing anything. Saw it on YouTube. Drain-o.

snake the lines with a 6 foot piece of string trimmer line. Easy. no damage and you can re-use the piece later or in the trimmer.

Do you know where the drains end, meaning where the water drips out, and are they easily accessible? Also, are there also 2 drains on the back corner of the moon roof as well? QX60

Thanks Duane for your thoughts! I had seen that on a video as well and I'm sure it works but I got so tired of having to consciously clear the drain lines every month or so that I wound up having someone install some clear vinyl wrap and covering the entire roof with it. We never open our moonroof anyway but now, it's totally sealed and I'll never be surprised to see my footwells wet again. Unfortunately, our car gets so much crap on it that I can never keep up with clearing those lines.

Not specifically for the QX60, but if you park on a slight incline, have someone pour water from a cup to the perimeter of the open sunroof....someone you trust! you will be able to see the water come out the holes on the downward facing tubes. Then turn car around and repeat for the other 2 drain tubes. There should be 4 drain tubes, 1 for each corner of the sunroof frame.

Where is this area in the photos? I have pulled up the carpet and styrofoam in the floorboard but can't figure out where these pictures were taken. Thanks in advance

I have a 2016 QX60. I had a similar problem with the hose coming from the air conditioner. I removed the hose from the ac condensor and a litre of water came out. After blowing air down the tube, it cleared and no more water.

I tried unclogging the drains with string trimmer line to no avail. The line would go all the way to what I perceived as the bottom of the drain hose and stop, but I could never find where the line was supposed to exit.
Since we never open the moonroof/sunroof glass on our 2015 QX60, I sealed it around the outside perimeter with Mortite Caulking Cord six months ago and haven't had any leaks since even through a very wet winter!

Ok peeps...heres the deal. Just did this on a friends QX60 that was leaking water into the passenger foot well.
1. The sunroof drain for the passenger side is a tube that goes inside the A-pillar, down behind the right side of the dash, and then connects to a disc with a nipple on one side and a "valve" on the other side.
2. The tube connects to the nipple on the disc, and then the disc fits into a hole in the firewall.
3. If you open the hood, take off the windshield wipers (pop a plastic piece off the top of the end of the wiper that connects to the car, under nut under that, and pull wiper off), take about 10 pull-grommets off the plastic trim at the bottom of the windshield, then remove that plastic trim, you can access the passenger side drain disc,
4. Once all the trim is removed, look at the bottom corner of the winshield glass, and under there will be a yellow-ish circle thing. In the center is a "valve" of sorts, which is where all the debri collects and causes the clog. Spray that with water or air from a can or pick the debri out with a toothpick. Problem solved.
5. I would suggest also sticking trimmer wire down there and moving it in and out a bunch of time while pouring water in the sunroof tray, to flush out any additional dirt.

You do not need to remove all the trim from the A-pillar or remove the glovebox. The above will suffice for the passenger side. I am still trying to figure out where the drivers side comes out - but may end up needing to remove the A-pillar trim for that one.

For the long term, just make sure you clean out the tray around the sunroof trim once a week to get rid of dirt and debris, so that it doesn't end up going down the sunroof drains.
