About a month ago, I brought my 04 to the dealer and he applied 2 fixes. One was to install the cabin air filter and the other was to make a hole near the gas pedal to be able to clean out the ac cabin.

This seemed to fix the problem until last week. On our drive back from vacation (10 hour drive) it was cool enough outside that we didn't have to use the A/C at all. Never even turned it on. There was a little drizzle, but barely any rain. By the time I got home, the driver side floor had about 1 1/2 gallons of water.

Took it back to my mechanic that applied the 2 fixes and said that the drain is clear and nothing is clogging it so he really doesn't know how this could be happening.

How is this possible if the A/C wasn't even turned on? Anyone have any thoughts on this?

Thanks,
Van.

 

I found this on the net. I hope it helps. It was a very easy DIY.

Very nice. Makes you wonder about some of these dealers charging $1K to fix this.

 

This is exactly why I stopped going to the dealer and found a local mom and pop shop to do all my repairs.

I stopped going to Mitsubishi about 4 years ago after they told me it would cost over a $1000 to fix the oxygen sensor. I pretty much told them I didn't need a new a-hole and never looked back.

My mechanic did this fix for me. In fact, he is the one that found it, applied it and corrected the issue. He also installed the cabin air filter all for under $150.

 

I recently had the terrible experience of having water flooding the carpet on the driver side and didn't know where it came from. I first thought my 2004 Endeavor had developed a leak in the windows or doors so I dried it out with towels and paper towels and a fan which took a week. I then performed the hose test and nothing leaked, but I noticed the carpet got wet again after using the AC for more than 30 minutes. I then Googled the problem and found the Forum which explained everything for me. Since my car is past warrantee I thought I would try fixing the problem myself, but after looking looking at the tight locating under the dash, I decided to see if my Mitsubishi dealer had figured out a quick fix that wouldn't cost me $1000.00. They knew all about the problem and fixed it with the bypass hose as is recommended in the Forum. It took them about two and a half hours and the cost was $240.00 including tax and everything plus a one year guarantee. I'm certainly angree that it happened due to a bad design, but I'm very happy Schumacher Mitsubishi in West Palm Beach was able to make the repair for me

 

I also had water leaking onto the passenger side carpet of my 2004 Mitsubishi Endeavor when it rained, or whenever I ran the AC.


I'd like to confirm that I also solved the problem successfully by using the instructions on in this thread [page 1, post #7 of this thread]. The posters username was "driver".


However, I have a few additional suggestions:


1] That persons photo #1 is only relevant in that it gives you a general idea of where the problem area is, so that when you look into the engine compartment (his photo #2) you'll know about where to look. Also, while his photo #2 is good for figuring out approximately where the hole is, the photo is taken from above the engine. But you'll need to get at the hole from under the car.



2] I have attached 2 additional photos that should provide some additional help.


Photo 1- In the first photo I've pointed out approximately where you'll need to position your head after crawling under your car (I backed myself in under the driver side door).


Photo 2- In the second photo I've given the view that you'll see when you look up from that position. The white wire (a coat hanger) in that photo is inserted into the hole. HOWEVER, there is a tube within the hole, which is what you want to unclog – SO, you really need to use a mirror to look into the hole first, so that you have an idea of where the wire needs to be inserted – otherwise you'll probably miss the inner "tube". I had a flashlight in my mouth to reflect the light into the hole so that I could see the tube within the hole. And I was using a small pocket sized mirror.



I recommend doing this after a rain, or after using the AC (e.g. while the water is leaking inside) so that you know when the tube has been unglogged. Water will pour out once you've succeeded.


In the end, to do the actual plunging/unclogging, I had my arms wrapped around a bunch of stuff in order push the wire into the tube (you'll figure this out with some trial and error, once you know see where the hole is). Got dirty and wet, but it was worth it – saved the $1200 that the dealer quoted me. Even my trusted mechanic said the only thing he could do was drill a second drain. Glad I found this thread.


It works!

 

had the same problem and was able to blow out drain which is on drover side. Now I have a blower motor problem. I have googled blower motor and resistor looking for parts but nothing comes back for 03 outlander. I have shop manual for testing motor and resistor but it does not mention part numbers. I am working blind as the Outlander is at my daughters 1000 miles away. Any help?

 

I have the same problem on a 2004 Endeavor. There is water on the carpet on the driver's side. Any suggestions on how to fix this problem for good. If I take it to a dealer will they normally be able to focus on what is causing the problem and how to fix it.

 

I believe this problem is a recall problem. Check the free carfax recalls for the Endeavor. Good luck

 

Mine is in for O2 sensor issue today! There are 4 O2 Sensors on this SUV. Each costing $174 ea. Labor 1 hour per. Labor $119/hr. But, without replacing them you get bad gas milage, raw gas odor and you fail emmissions test at the DMV. Thankfully the heater went bad on only one of my sensors...but I know that I still have 3 more....not holding my breath though, I am finding out this is a problem with these vehicles. Honestly, Im not sure I will buy another. I have a Subaru that has been running strong since 1993. It runs better than my 2004 Endeavor.
