Ran into my first issue with my 2016 CX-5 GT (kind of a odd one)

Well I pulled the little drain hose off, little bastard was tough to get off. Managed to snake a soft wire up it for about 16 inches, blasted it with a can of air, felt no obstruction and nothing came out, Also snaked a nylon tie wrap in the lower plastic part that the hose attached to, no obstruction there either. Big rain storm coming tomorrow night so we'll wait and see what happens.

Hmmm okay I'm stumped now.

Wait that panel cover. The water came from the section nearest the front passenger tire right? There may be a seal leak from that section. Gotta use a flashlight to inspect up that way.

Sidenote- you can give us a tutorial on the drain plug now :)

No, water was closest to the middle. Actually had no water show up today, had heavy rains and had the a/c on- was very humid today. So maybe I knocked something partially clogging or something. I used the tutorial by blackcx5 posted in post #18.

Yeah I sure hope so. A partial clog is probably the best explanation right now. No leaks after heavy rains indicates a non-external issue. Where exactly was the hose?

you got a clogged AC drain, save yourself some money and time : you can easily fixed yourself, see tomcat1446's thread #19 in this link, he also linked a video from youtube titled "CX-5 water leak" stealerships charge like $175 for this, what a scam, they say they have to remove the dash to get to the AC unit, what BS..

https://www.mazdas247.com/forum/sho...a-c-drain-and-remove-musty-smell-easily/page2

you probably can hear water sloshing sound as you make hard turns, make sure to clamp that rubber tube before you remove it otherwise a whole bunch of water will start pouring into your passenger footwell... see thread#1 in link:

https://www.mazdas247.com/forum/sho...nclog-a-c-drain-and-remove-musty-smell-easily

get a can of compressed air and zap out any clog in that rubber hose or the white connector on the floor that drains to under your car, confirm by using a squirt bottle and squirt water into the drain tube and make sure it comes out underneath your car.

also, it may be a good idea to get a can of Kool-It from Amazon and spray the coils, to prevent mold and mildew if your drain was clogged.
Has anyone found a permanent fix for this? I’ve had to vacuum the water out of mine a few times now and the blower just died on us. I tried the link to unclogging it but it didn’t work.

This’s a design issue and you won’t be able to find a permanent “fix” for the problem.

In your case you want read through this entire thread and find any information to suit your symptom. IMO your problem is different from OP’s, and your water could be coming from outside source; hence affected the blower motor which was died. An easy way to figure out this is if you see water when it rains, or if you water the windshield in the area of air inlet with AC off, this indicates the water is coming from outside. The discussion here on the water leak is mainly caused by condensation from the evaporator of the AC unit. You will see water only if you keep the AC on for a period of time,

In both cases, if you don’t see any water dripping to the ground under the car, the drain hose is clogged.

Once you figured out the water source, you’ll have a better chance to fix the problem “permanently”.
 
Thanks so much for the info! I'm sure it's a condensation draining issue, as it makes all of those sloshing noises during left turns now that we've been running the AC more than usual. When I shopvac it out, it typically drains for 15-20 min, so a lot of water builds up in there pretty quickly. One way I'm pretty sure it's not an outside water issue is that the problem recently happened after we'd been without any precipitation for nearly 5 days. Of course, there could always be two issues happening at once, but I'm pretty sure it's a clogged drain.

Seems crazy to me that Mazda hasn't really addressed this since it seems to be a common, pervasive issue across multiple Mazda models. Crazy, but not surprising, I guess..

In theory the drain tube if it isn’t clogged should be able to get rid of all condensation water accumulated in the unit eventually even if you’re living in a high humility environment. If you can hear sloshing noises during left turns now, the drain tube isn’t functioning. Try to clear the blockage in the drain tube with methods mentioned in the thread, It’d be hard for me to believe if the accumulated water can be sloshing around when the drain tube is functioning.

Yeah I noticed that many older links posted no longer work for some reason. Those old links were still working after the website update, but happened at the time few weeks ago when the number of posts displayed per page changed from 20 (changed from 15 to 20 after the website update) back to 15 (at least on my iPhone). Hope Antoine has been aware this issue.

And always like great write-ups by tomcat1446. Unfortunately pictures in this write-up are all missing and not sure if they can be recovered.
