Default A/C Condensate Drain location...?

Getting water on passenger floor from A/C condensation. Cannot see the drain on the firewall
for the A/C. I see the larger rubber tube for the cowl drain only. If I remove the access panel in
the passenger side wheelwell will that give me access to the ac drain? As always, appreciate the
advice and guidance.

You have a much better chance of accessing it from the bottom.


Plugup may not be in the external tube but rather inside the pan that the evaporator core sits in:

Post #14 has diagrams of Evaporator core.

Thanks for all the guidance. Was hoping this could be accessed from the top. Even with these pictures, I cannot
see nor feel this tube from above. As you suggest, I'll likely have to crawl under. Part that confuses about this
passenger floor dripping is I'm original owner, 2001 Coupe, 29K mikes, ALWAYS garaged, never been in rain, stored
with a cotton cover in the garage. So how did this become clogged???

I just went through this. I jacked the car up, laid under it so I could see the drain tube. I removed (and lost) the drain tube with long reach needle nose pliers. I then took about 18 inches of thin wire (picture hanging type) and pushed it into the drain area. That's when the fun started. You won't be able to move out of the way fast enough to avoid taking a bath by the half gallon of water that will come gushing out.

I was not able to get the wire through the drain elbow, which is why I removed it. I currently and running with no drain elbow at all.

Good luck. It's a PIA to get to.

from dust and pollen getting pulled on to fins and then dripping off into the condensate pan

Thanks you for the guidance. Yes, does sound like a pia. Was hoping the wheel-well acces panel might be easier. Earlier posts
are little unclear if the access-panel allows reach to this A/C drain???? Oh well....guess its jack up, crawl under and rain coat.
Thank again....appreciate you sharing this.

unclear if that tube is readable

The wheel well access was completely useless for me. I read that in other posts as well. If you have small arms, you'll be a lot better off. Obviously the car needs to be completely cool as you'll be up there with the exhaust etc. Start to finish, took me about 30-45 mins.

Thanks...not looking forward to this. I'm still at a loss why this is clogged??? Garaged since day one(orig owner), NEVER been in the rain, covered with
cotton sheet in the garage. Only water it see's is when I wash it. Strange.

Think about sitting a glass of clean water outside, covered for years. It can't evaporate since it's sealed up, so it scums up. That's all it needs to start the clog. General driving, sitting at car shows etc and next thing you know its clogged with snot and dust. Not uncommon

These find friends here just helped me. It's behind the right head and the firewall. Line of sight is blocked by the wiring harness, it's just below and behind it. Get a good flashlight you'll find it. I got it off from up top, but good luck getting it back on that way.

I agree, when I do get under the car again, I’d actually like to snip the end of the pipe slightly so as to cause more opening. That of course if I can reach the dam thing. Just a thought.
