A/C Condensation Drain Leaking

[Irenicus]

I've recently discovered a lot of water leaking into the foot area of the passenger seat. I thought it may have been the sunroof - I snaked it and blew about 20psi of air down it and confirmed it drains fine on the passenger side although the driver side is definitely clogged.. but I figure it drains on the drivers side and the water is only in the passenger side

I pulled the carpet up and found it looks to be coming from the AC condensation line. I don't know the next step here - it doesn't seem clogged, I run the A/C and the air blows out of the inlet.

Do I need to take a vacuum to this thing? I still have no idea where or how the water was leaking out of it, the hose looks fine and the 90 degree plastic insert that I figure drains out the bottom looks clean also..

2016 CX-5

(ex Auto AC Tech Here)
Either the drain hose is blocked (usually on the outside pf the vehicle where it goes through the floor/ firewall)
Or the fitting where it attaches to the AC/ Heater box is cracked (some passengers can inadvertently kick it and break it)

Interesting. The more I'm reading tends to lean towards the driver side sunroof drain clog or a possible cowl leak. I haven't been using AC at all and it's been raining like hell here. I guess the drivers side drain will leak into the passenger side somehow

Kind of a nightmare ugh

pick one from the 3:

ac condensation pipe (detach down pipe and pour small quantity of water with a syringe, it should exit below the car)
sunroof drainage (need removal of pillar covers)
new windshield (if they didnt glue it properly)

I had this issue with a previous car I owned. Couldn't find anything wrong with the evaporator/heater core enclosure or the pipe leading out from it. I got under the car and stuck a rod up through the drain tube and a ton of water started pouring out.

I guess I need to remove the pillar covers on the drivers side since that drain won't drain out.. I still don't see the water pouring into the passenger side though

Which drains from the bottom? Trying to get a list and tackle everything tomorrow

It should drain out the bottom of the car through the floor pan based on your pic. Some might drain out the firewall. I'm not exactly sure where the drain is for the CX-5 as I just bought this car and haven't been under the car yet. I'll be getting under the car soon as I'll be doing the first break in oil change.
