Hey, everyone. I'm new to Hondas and this forum.

I recently purchased a 1997 Acura 2.2CL to use as a daily driver while I have my '94 Twin Turbo Z32 in the garage for a little maintenance/upgrading (the Acura will likely serve as a daily driver even after the work is complete).

A few days after taking ownership of the vehicle, I noticed a significant amount of water (definitely not coolant) collecting in the passenger side floor board. It has been raining here, so the first thing that came to mind was a leak somewhere in the weatherstripping. Then I looked around that area and found a black triangle-shaped box with a soft rubber hose coming out of the end that is closest to the firewall. Being new to Hondas, I have no clue what this is, and a brief search here yielded little results (maybe I'm searching for the wrong thing...).

The aforementioned box had a considerable amount of water on it, almost seemed like condensation. I'm not sure if water is leaking in, or if there is just an abnormal amount of condensation on this box and it is dripping onto the floor. If this sounds familiar to any of you, please let me know how to go about addressing it, as I would like to be able to fix this by the weekend.

Thanks in advance for the info.

If you've been running the air conditioned, that may well be the Evaporator Case.
There are three things which will leak in that area.

1) Windshield (clear water, only when it rains)
2) Heater Core (oily water / green, any time car is running and system is under pressure)
3) A/C Evaporator case drain (clear water, only when A/C is on)

Sounds like the evaporator case is a likely choice. I'll dig into it this weekend. By the way, does anyone have a factory service manual in PDF form that I can use to get this job done? Thanks again.

 

Debris clogs the evaporator water outlet. Put a pan or plastic on the floor to prevent the floor from flooding. Disconnect the drain hose from the evaporator water outlet. Using a stick insert into the water outlet to remove the debris. Be careful do not damage the evaporator.

 

Alright, sounds simple enough. When you say "be careful not to damage the evaporator", what am I looking for? Is there a filter of some sort that I need to be careful not to puncture? Thanks for the info.

 

Do not put the stick too deep and touch the evaproator. Actually, when inserting the stick a little bit and move around inside the outlet, you will be able see water and debris coming out.

 

Gotchya. Thanks again for the help! The more I think about it, the more reasonable this sounds. When I take a (relatively) hard right corner, the evaporator case seems to spit out more water...

 

Confirmed: glogged a/c evap case drain.

 

Alright. Thanks for the confirmation/advice! I'll tackle it this weekend.

Thanks again, everyone!
