Question about 2002 Mitsubishi Lancer
My Lancer is leaking water from the ductwork through the blower motor, and on to the passenger floor. It only leaks out when I make a sharp left turn, and only on the passenger side. It is not antifreeze/heatercore, and I have had the windshield checked for leaks. I believe it is condensation build up, but it seems like an awful lot of water for that, so I cannot be for sure. Any ideas as to what might be causing this? How to check it? And finally, how to stop it?
I can't believe I found a site that talks about the exact problem I'm having with my '02 Lancer. It must be a common problem for anyone living in a humid climate. The hurricanes here in Texas produce this problem almost state-wide as all of our A/C units are flowing water like crazy right now.
I'd like to expand on the solution that briankc43 so graciously provided above. The drain tube for the condensate reservoir is, indeed, found on the firewall on the driver's side (left hand drive vehicles if there's another). It's a small (1-1/2") rubber tube bent 90 degrees pointing down. In order to get to this tube you will probably have to remove the air intake tube that houses the (I'm guessing here) MAF sensor in order to get your hand down to that area. Once you've cleared the way for your hand the tube pulls off easily from the reservoir drain port that pokes through the firewall. When I did this there must have been nearly 1/2 gallon of water that flowed out! If you have a small, narrow bottle brush it would work nicely raking what muck remains in the interior of the condensate reservior. At this time I do not know if there's any way to introduce more water into the reservoir in order to flush it but this should be sufficient. I guess you could rig a small tube and funnel or syringe to squirt water into the drain port. If this works it may not be such a bad idea to mix a very small amount of bleach into the flushing water to help kill off any fungus as it's a pretty darn good place to grow a fine crop of it!
Because the drain tube narrows by about 1/2 at its end it encourages stop-ups with the dirt and fungus that grows and is deposited in the reservior over time. I thought about leaving the drain hose off but if you did you'd leave yourself open to the possiblity of water getting back into the interior during wet conditions (water splashing up on the firewall) especially if the foam seal on the inside of the firewall was damaged or deteriorated.
I hope this helps those that have been monitoring this site.

I had the same problem in my '02 Lancer, and I found that it is a design flaw in the evaporator. It gets clogged with debris and feeds back through the blower. I remedied this by removing the drain hose (it's an "L" shaped hose coming out of the firewall), and, using a 4 ft. piece of tubing into the evaporator, siphoned out the junk clogging it up. Quick, easy, and free.

There is a filter the dealership will retrofit, it was not installed at factory basically because mitsubishi basically assumed that everyone driving this car would park it in a garage all the time, not needing a debris filter.....

I had the same problem on my 2002 Lancer a couple years ago. When I check the blower on the passenger side, I noticed it was missing the hose. I tried replacing the hose with a generic brand, and ended up restricting the flow, which in turn burned up a sensor. But it was definitely a hose problem.

Sounds like your drain tube for the A/C is clogged up. Get someone to blow it out for you, and you shouldn' t have this problem anymore.
