I know that this has been addressed in a few other posts but I can't figure out my problem. My 2002 Eclipse Spyder GS is somehow leaking. How do I clear my evaporator? I can't seem to locate it. I have already taken off my glove box because in a previous post someone said it was behind there.

Well it would help to know what you are leaking

I believe that it is just water. With the upholstery up I'm going to run the AC to see if that is the problem. If it isn't then I guess rain water is getting in somehow.

Okay after allowing the silicone to cure for 24 hours I cranked the car up and let it run with the AC on full blast for 30 minutes. Giant puddle of water... UNDER the car.. no water inside! FINALLY.

The silicone did the trick for me. Now just to put everything back together...

Heres a little guide I put together on my experiance for anyone else who is trying to solve this same issue. I've listed things in order of dificulty from easiest to hardest. Hopefully this will solve a lot of frustration for everyone. I will later update it with pictures as I reassemble the interior.



Heres how I trouble shot mine:

1 Check to see if your drain tube is clogged and causing the water to back up into the evaporator pan (the one at the lowest point on the dash). Clearing the tube should be your first attempt to fix it. I used a coat hanger and a pair of pliars to bend the hanger and removed the air intake assembly to access the firewall.

2 Check your evaporator pan to see if it is clogged with junk from the lack of a cabin air filter. Only the 2000-2001 cars had this filter. 02+ do not. You can gain some access to the pan by disconecting the ducting after the blower motor... access it from under the pass side glove box area. I cleaned a whole handful of leaves/hair/gunk out of there. Then flush it with a few gallons of water to make sure your drain tube is working. You can add a cabin air filter pretty easily.. there is still a template on the ac blower for where the filter went on earlier cars. I plan on doing this as well in a few weeks.

3. your drain tube can be fully functional, but have a bad seal around the firewall. This is what was wrong with mine. There is a cheap foam gromet that mitsu used where the tube exits the cabin thru the firewall. Mine was still leaking thur there even after clearing the tube and pan. My answer was to silicone the living crap out of that area around the tube. Its not easy to get to it.. but I was very liberal with the silicone so hopefully it fills in any leaks.

4. could be other things like a crack in your pan... heater core.. ect. However, I would guess its one of the first 3 things. Especially if its pure water.. no antifreeze or anything. I'm new to the 3G world, but in my research on the web... seems like the drain tube is almost always the culprit.

PS your drain tube exits your firewall into the engine compartment on the drivers side... right next to the steering column. You will see a small tube protruding about half an inch straight out from the firewall. It does NOT look like a drain tube and you will probably search for it for at least 20 minutes. I did. Its located right next to the motor mount, twoards the bottom of the firewall and you may have to move some of the heat shielding mat to see it. You will not be able to see it by crawling underneath the car. Best bet is to locate it from the top by taking off the air intake and if you need to, navigate by touch to access it from the bottom. Not a very accessable spot for the tube if you ask me.[QUOTE]


There you go

U need to take out the whole dash watch out for ur airbags **** likes to go off wait at least a hour before pulling stuff. also call mitsu about how long for ur certain year and model for airbags.
