A/C Condensation dripping on passenger floor carpeting. Web Forum suggested that evaporator drainage could be clogged up and that blowing pressurized air into drain hose and into evaporator housing could remove the clog. The drainage hose can be seen at the very bottom of the evaporator’s lower housing (passenger side). Warning: have a towel ready and place it underneath the hose. I removed the hose and I blew pressurized air into the hose and then into the evaporator assembly. As soon as air was blown into evaporator assembly, the plug was released and a lot of water came out. Good thing I had the towel handy. Keep in mind the ECM (computer) sits right underneath where the water will come out. You don’t want water falling on the ECM or any of the electrical connectors down there. I think the clog was caused by foam that falls off the ventilation doors found inside the evaporator assembly. As the vehicle ages, this foam will rot and especially when you set the fan speed to ‘3’ or ‘4’ the stuff will be blow off the doors and some of it will work its way to the bottom of the assembly causing the problem. Easy fix. Need monitoring.

i just bought my 1994 honda accord ex a couple weeks ago..i had to replace both of the fans due to my car kept getting hot. so now it fine and just 4 days ago water started leaking from the driver side right next to the gas pedal..and now it is on the passenger side..on the right side and left side of the glover compartment. why is it jumpin from place to place..would it still just be my Evaporator Drain, or could something else be affecting it also? because the condensation is making my car have a real bad odor?

cheap fix, but but very annoying to have water pouring onto your feet while turning(mainly) started on passenger side and eventually made it to drivers side floor
