Does anyone know where the drains go on the sunroof of the S40? I am getting a ton of water on floor of my car when it rains, and many internet searches make me think the drains are clogged and the water is being re-directed inside. I'd like to avoid paying the dealership $500 to fix it if I could legitimately find where the drains go an unclog it myself. <p>One user posted a great thing in the XC90 forum, but I don't know if the design is similar.<br>

Just went through this drill

The drain tube starts at the corners of the sunroof frame channel, and goes down the pillar (both sides) to a point below the corner of the windshield. At that point the tube plugs into a rubber fitting which passes through the "firewall" to bring the water outside the cabin. If you remove the door weatherstrip and then the trim from the pillar you can see the tube and the top of the rubber fitting.<p>The very end of the rubber fitting, for some reason, is crimped into an "X" pattern and that is where the clog usually occurs. As the water backs up behind the clog it reaches the point where the tube is inserted (not sealed, and in my case actually disconnected) and allows the H2O to overflow inside the cabin. It goes down the wall under the carpet by your left foot and gets to the floor. It finds the back seat because it's the lowest point. <p>I ended up taking out all seats and pulling up the carpet to get it completely dry. (I wrung out as much water as possible, sprayed with water/bleach mix and set up in front of a big box fan...took an entire weekend.) It's important to get it dry, though, because of the smell, and fact there is a LOT of wiring down there which will stay wet until you get it fixed.<p>I sealed the tube into the fitting with some silicone sealant and so far so good.<p>From outside the car, to get at the end of the drain fitting and check for clog and clear it out you need to remove both wiper arms and CAREFULLY remove the cover from the pan where water drains down from the windshiled. (One guy broke a windshield at this step as there are two rotating latches which grab the lower edge of the glass in the center (at least in our model, 2005). The latches have a dot stamped on them which is pointing up when latches are engaged).<p>This is a big job and $500 is less than half what they charge around here.<BR><BR>

Re: Sunroof drain clog? (Volvo S 40)

Just did this repair yesterday on my 2005 S40 T5.<br>my fiance called yesterday morning and sent me a pic of about an inch of water in the drivers side floor. Rainy season has arrived here in the great state of Washington!<p>The fix is pretty simple and there are no gotcha's that I found.<p>Quick writeup on how to do this.<p>First, pull the affected side (driver or pass) A pillar cover off. Note: You don't need to completely remove it to get it out of the way and have access to the drain tube and the rubber drain fitting. There is a length of plastic that keeps the A pillar cover from becoming a projectile in the event of the a pillar airbags being deployed. You don't have to remove the cover completely.<p>Once you have the cover out of the way, you can see the largish diameter drain tube running from the ceiling down to the bottom of the dash right under the window. If you have huge hands, you will have a problem getting to the rubber drain attachment. <p>So my drain tube had come out of the rubber drain so this is why I was getting a ton of water in the compartment. Knowing that the end of the rubber drain is "crimped" or a better description is shaped into an x pattern, causes this area to become clogged with slime, grease, dirt, etc.<p>I've read that the rubber end is shaped this way to cut down on the "whistling" that can occur as wind crosses the opening of that tube, just like what happens when you blow air across the opening of your favorite beer bottle. <p>Well I just cut that end off and now have a nice, free flowing clog proof drain.<p>The previous poster said you need to remove the wiper arms and wiper arm motor cover to get to the drains. This is not necessary, nor even needed. The sunroof drain plugs are not accessable via this area. All the work is via the interior of the car.<p>Getting back to the repair.<p>Its a tight fit when putting the drain plug back into that hole, but with some patience, you can get it to pop back into the hole in the chassis. Wiggle it, push with a finger on the top, turn, wiggle it, whatever you need to do to get it to get back into place. Its not hard, just somewhat hard to do due to the tight area you are working in.<p>Now that you have the drain plug back into its location, you need to put the drain tube into the rubber drain. PLEASE NOTE: I had originally intended to put the drain tube into the rubber elbow first, BUT it was easier for me to make it a two step process since it allowed me to manipulate the rubber drain without having the drain tube in my way.<p>So I cleaned the drain tube as best I could, but there wasn't any obstructions inside the tube itself, your milage may vary here, but mine was clear. Slid it back into the rubber drain and with some pushing, I got it to seat pretty far into the drain. Again a little patience here is needed since that rubber drain is somewhat soft and tends to move around when putting the drain tube down its throat. <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/smile.gif" BORDER="0"><p>Once all that was done, I tested the assembly by pouring some water from a container in the sunroof well area, and watched the water drain down the tube, and onto the driveway instead of the interior of the car. <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/smile.gif" BORDER="0"><p>Popped the A pillar cover back on and called it a night.<p>I will be doing the passenger side as a bit of preventative maintenance and will take pictures of this and post them for all to see.<p>My narrative here tended to go the story route versus a 1,2,3 step by step process, but if you need more clarification, feel free to ask and I will help out.<p>thanks<p><BR><BR>

Re: Sunroof drain clog? (stealth)

Just finished the pass side repair. Took all of about 10 minutes now that I've done the driver side and learned how to do it.<p>guess I have to host the pictures on a photo site and link them here?<BR><BR>

You guys are fantastic. You just saved me many $ and a trip to the shop. It took me an hour and some frustration with the trim, but I found the tube disconnected and once it was plugged back in, my drain sends water to the floor of the garage and not to the floor of the car. THANK YOU

Re: (norse2)

thank you, cryhavoc and volvo125, for those procedures. having had numerous blockages, and soaked carpets, i plan on doing preventive clearing twice a year.<br> has anyone found a good way to get a blockage cleared? is there something that can be pushed through like a plumber's snake? or a way to get compressed air into the tube?<p>thanks for any suggestions.

Re: (dushan)

I tired compressed air which does not work as for plumbers snake that may loosen the connections between rubber hose. The best solution that I found was to use a garden hose and try to rinse out all the dirt out on the sunroof drainage system. Let me know how that works for you

Are you sure it's a blockage and not a disconnect between the hose from the sunroof and the rubber fitting that goes through the "firewall" to the outside? If the water is ending up inside the car it indicates, at the very least, that connection is leaking otherwise the overflow would occur at the sunroof itself. If the connection is faulty you don't need a blockage at all to get wet. Hate to see you solve only half the problem and end up with wet carpets.

Re: Sunroof drain clog? (cryhavoc38)

Your description seems to indicate the drain runs through the front pillar. I've now had this leak problem twice <IMG NAME="icon" SRC="http://www.vortexmediagroup.com/images/banghead.gif" BORDER="0"> (1st time the dealer fixed for free) and this time around I'll try to fix it myself as I've moved and my local Volvo dealer is not the most friendly. <p>Anyway, both times I've had water in the REAR passenger side footwell in my 2004.5 S40. It would seem the drain line runs through the middle pillar (???). Are there two drain lines for each side? Or is the line possibly disconnected at the top with water simply running down through the central pillar? Anyone have input on this for me? Does anyone know of an online source for a drain diagram for a 2004.5+ S40? I've looked but can't seem to locate one.<p>Thanks

Re: Sunroof drain clog? (roman1766)

I followed cryhavoc38's instructions and it worked like a dream on my 2004 1/2 S40. Pretty easy repair (if you have an air compressor). The line from the sunroof to the bottom corner of the pillar was clear with the clog being somewhere below that; thus an air compressor was needed to clear it out.<p>Had to rig up a hose with a valve back a bit a few feet the tip of the air line as the top of the drain tube at the window is in too tight of a space to allow my normal valve setup to fit in. I used a hose repair fitting (looks like ice cream cones stacked inside each other) to fit snugly into the top of the line (don't push too hard as then the hose repair fitting will "bite" into the hose and will be next to impossible to remove.) Gave it a few blasts with 125 psi. Hooked the drainline from the sunroof back up, poured some water into the scupper along the edge of the sunroof and happily watched the water drain out behind the front passenger-side wheel.<p>About 10 min start to finish (after an hour or so of figuring out what the heck I was doing and reading through all the advice in this discussion!)<p>Thanks to all the previous postings.

I think it isn't so much a clog as it is a bad design. If there is any slight blockage, the water should be able to push it out but because the tube slides out of position so easily, it can never quite push out the blockage. I'm thinking if this happens again to my car, I'm going to try putting a little silicone or something to keep that tube in place.<br>

Just joined because I just had this issue and I am facing a $1200 bill. Anyone contact this law firm to see what they are doing: www.Volvo-Lawsuit.com ?
ooo i've got an even better story... i let them charge me $1200 to fix the sunroof drain issue, and i take the car home, it rains a week later, and the backseat fills up with water AGAIN. I took it back and they tell me its a completely different problem (a/c leakage) and they want to charge me FULL PRICE AGAIN to repair it... what a load of BS this is!!! what a coincidence that would be that two completely independent problems occurred a week apart. ugh. i hope i can straighten them out. soooo frustrating.

Holy , Wet Well Feet

I heard of a few having small Issues , but compared to other Volvo's , My V50 has Been real Good
I even left the Roof in Tilt Fresh Air - Open - 1 night by mistake and it rained all Night .

Nothing Not even a Rain Drop on the Seats , it rained pretty hard , I think the Rain was Blowing Drifting up against the Tilted Sunroof Angle - It's Been Really Good .

At Least It Sounds Like something We are able to Fix @ Home . :cool:

New Sound trap design

Just got back the dealer from round 2 of wet feet within 9 months. In December they cleaned the drains (for $90) and I figured I was good for a few years...wrong. This time they "confirmed" that they were clogged again, but told me that Volvo has come out with replacement sound traps that aren't crimped at the end, so won't clog as easy. The replacements are only $15, but $360 to install. Since this issue is caused by debris, it's not covered; even though they recognize it as a flaw and have developed a solution!! They did offer to pick up 20% of the cost, as a gesture of goodwill.
2 months after I paid $450 for a new flame trap, I got the bulletin announcing that defect. It only took 4 months to get reimbursed. I'm thinking this bulletin may be in my mailbox next week.
It's gonna be a clear weekend. I'm going to try the home remedy;and if I can get to the elbows, I'll pick up the replacements on Monday and install them.

btw....I've contacted the folks at www.defectivesunroofdrain.com and added my name to their list.

Help! Brand new to the forum. I too have a 2005 s40 with a leak somewhere. After a heavy rain, I have over an inch of standing water in the REAR passenger side foot well. Where would the water be coming from to end up here? Most of the people on here have front foot wells that are getting wet and have success with cleaning/replacing the lines for the drains leading from the front drains on the sunroof. But since my front foot well remains dry and only the back is soaked, wouldn't it make more sense that the rear passenger side drain has malfunctioned? How do I locate the drain in the sunroof and uncover/access the line leading outside the cabin for this drain? Anything else that could be dumping water here from after a storm (i.e. car is stationary with engine/ A/C off)? Yes, I am 100% certain my windows and doors were shut and have a water tight seal. Thanks for any help!

The rear foot area is lower in these cars than the front and water will migrate there. Had the same issue but on driver's side. Driver's side not terribly wet but rear drivers side was soaked. Front driver drain hose on mine is constantly coming off. I'm about ready to superglue the F'er in place. Your sunroof has 4 drains. 1 at each corner. So yes it is possible the pass rear drain is loose but why not check the fronts as well. Removing the A pillar cover is easy. You'll probably find your problem is indeed the front drain hose.

Had the AC drain plug come off, leaves a mess on rear passenger side, and it is a pain to dry it out completely. All this with clogged sunroof drain seems odd to me. What is the odds of debris getting into it?
I think it must be alge growth, if that is the case - an occasional flush with clorine will do nicely. Stay clear of draino though..
