Cadillac CTS leak sunroof water leaking through headliner

*** update I bought this air pump (AIRHEAD AHP-1 Airhead Hand Pump) to air blast the drain tubes and it works perfect

Just spray or pour as much water down the drain tubes as you can then quickly attach the air pump and pump it as fast as you can several times and repeat till the drain tubes are clear.

*** update, I also found that you can access the drain tubes in the trunk. You have to peel the trunk carpet back on the sides and you can access the tubes at the wheel well.

*** another helpful update tip... I haven't tried this yet but I'm sure it will work if water is still leaking where the tubes connect to the roof. Try using ad seen on TV flex seal and spray the connecting part and it will turn into a rubber seal.
You can buy it at your local store or

This is a 2008 - 2012 cadillac cts leaky sunroof coming through the headliner. Save $1-$2,000 in dealership repair costs.

after you fix this leak, the next step is to get the stains out. to do this, take a cotton rag, get it very wet / damp and use some dish soap like dawn. then rub the headliner out with a considerable amount of pressure. after you get the stains out, once it dries you may have to repeat if necessary. with time it will look like new.

GREAT SIMPLE

You have just fixed my water leaking issue into the sun visor area!! Im a female and I try to do everything on my own. With your informative videos ...a lot of us can DIY!
Thank you.

Thanks shawn! I did the frontsand still had a rear leak. Now I know I have to do the rear drain tubes also. Thank you!

[richardbradner]

EXCELLENT! GM should hire this guy! Just saved me over $150. More so, I love my CTS again. PS. WTF is wrong with Cadillac engineers for this lame excuse for a drain hose! Make is bigger and have it drain to outside!!!!

Had mine done 3xs now. Still a small leak. It's that box in middle back of moonroof. Mine was cracked. Epoxy it. Still a little leak. Pissing me off. Have a headliner guy fixing it. Thank God

Helpful video. What I've found works for me is to snake out the four drain tubes with 0.095" weed whacker line. The rear tubes can also be accessed at about their mid-point from within the trunk - one is within the battery compartment and the other you'll need to unscrew about four plastic fasteners and then pull the the trunk liner back a bit to access the other.

I had an issue where the headliner needed to come down. You saved me big! Thanks!

[patriotman]

You are absolutely right. I have a 2008 with a leaking sunroof and this video is a great help.

[gduncanjr]

Perfect. Knew they existed but didn't know the way to gain access to them so thank you-thank you!

[sapiendounitas]

You indeed saved me a bunch of money! Thanks so much. I'm gonna do this tonight, and I'll let you know how it turns out.

[susanstokes]

Thanks for the info. Will be pulling down my headliner tomorrow and try to fix this myself.

I also found that if you peel back the carpet on the sides in the trunk you can get to the drain tubes in the wheel well

Oh Em Gee! Thank you so much for posting this. And I will say, if I can do this, ANYONE can do this! I followed your instructions (of course I had to to go the store first to buy a socket wrench with an extender to be able to get those screws out of the oh shit handles and the spot behind the airbag covers), but wa-la...I was able to get to the drains in the back of the car by dropping the lining. My snapchat followers have never been so impressed. ;) I am just soooo happy to have saved the money because I took it to Cadillac the first time this happened, and was over $2k because it had been leaking so long, they had to even replace the carpet on the floorboard that was molding. Again, thank you so much for posting this! Much appreciated.

Nice video! I'm a Cadillac specialist & apart from clogged drains, I see the front drain hoses leaking where they connect to the rubber tubing on the sunroof. You have to drop the headliner some in front & install some hose clamps on the front drains.
Working on 2010 right now, along with computer issues where I can't communicate with any of the computer on the high speed bus. I'm assuming it was from water intrusion.

thanks for making this video. i came back from a month long vacation to find a pool of water in the back of the car and mold beginning to spread. it was pretty rainy at home while i was away i guess. Aggravating but it looks like a simple enough fix. i hope this is all it is

[michaelh]

Awesome info just purchased a used 06 cts with same problem knew how to do front drain holes but wasn't sure about rear ones now I'm a 100% confident how to fix leak and then go have headliner professionally cleaned thx

[porcanada]

If you want to save lots of time, use a vacumn cleaner at the end of the drain behind the wheel to unblock it.

[aronhill]

Thanks for the info on repairing my leak in my 2012 CTS. I’m going to work on it today. Thanks again.

[JamesWrightTellingOnGod]

Thanks so much for this information. This worked perfectly on my Caddy.

To make it a bit easier check the weather out and if u see it's going to rain just put clear tape on the sunroof. Take it off after it rains.👌
