Possible Leak

Possible Leak
Whenever we get heavy rains my car seems to go nuts... What I need from you guys are suggestions on where I can check to make sure it stays nice and dry. Maybe I'm missing a piece of rubber somewhere or something.
Here is a list of what happens every single time and the problems are ALWAYS the same there is no change to the list.
- door open indicator doesn't work
- memory seat buttons don't work
- seat belt indicator doesn't work
- Dome lights do not work
- Climate control displays some funky crap, lights up but doesn't
- speedo doesn't dim correctly
- Driver side front window is the ONLY one that works with the master switch. Passenger would have to open and close their window with their switch
Thats about all I can remember off the top of my head. After about a day or 2 everything starts working again.
I saw one other member had this issues but I have no clue if they resolved it. It was a pretty old post.

i mean to a T i have exactly what you have, i have found a solution to the seatbelt light though, if im driving i turn car off, unbuckle seatbelt, re-buckle and restart and it works fine.
i will tell you what i know about this from my car
something is getting wet either inside my door or under my hood thats for sure and we both know that but lets see if we have the same problems.
i have had my windshield replaced and my car was in a minor accident(before i bought the car so i know the windshield was replaced but i dont know what else) when i first got it, it had a water leak into the car from above the steering wheel (but again ONLY when i was in a pressurized car wash) so i siliconed it some and it doesn't drip anymore, my rain guards around my tires and my under engine splash cover got ripped off while on the interstate in Atlanta and its possible water is getting in from their but more and more im suspecting a incorrectly sealed windshield. i dont have water in my floor up front but the other day i noticed when i ran my nav override i had wet carpet in the passenger rear floor but ONLY under the carpet so im assuming this is a separate problem (im leading to believe the drain, dunno what its really called....those black circular holes another member recently replaced in his DIY for wind noise) under the car needs to be replaced if anyone knows what im talking about could you possibly link me to that post to? im gonna go ahead and change these
MINE only happens if i take it to a particular car wash (yes i know i shouldn't and now i def hand wash) or if it rains EXTREMELY hard, not just a normal rainfall.
if you roll the passenger windows down while its doing this they will "trip" and not work again till it dries out (dont think mine even work with their switches and since yours does this is starting to make me think its a door or some other ecu)
a few weeks ago mine werent working after the rain and the ice and i suspected the rain had frozen and whatever is doing this was frozen shut so i brought my car into my warehouse at work and let it thaw. At the end of the day eveyrthing worked fine. so i know when it dries its ok but its starting to concern me seriously
when i continue with my audio build and remove my door panels to dynamat my doors i will probe into the door and see if i notice anything....again im really wanting to replace my windshield but havent done so yet
anyone else with problems like us car to chime in?

I thought I was alone. haha.
I have noticed no leaks from the windshield. I will check to see how the carpet is when it happens again.
Yes I discovered the same trick with the seatbelt too.. LOL...
My CF hood does let some water in. I've been slowly trying to seal it off to eliminate that as a cause.
Let me know if you find anything in the door because I suspect that is where the problem is. Hopefully the weather will get warm soon so I can take a look into this deeper.
I have been on hold since my car needs the wheel hub changed and I haven't been driving it for the last few weeks.

Seems like communication system failure. Probably a stripped wire.
Here's a little something about troubleshooting:
http://bahamutcars.free.fr/workshop/.../m_di_0803.pdf
So, if you want to know exactly what's going wrong you need to 1) get the car to fail, 2) scan error codes. To fix it you'll probably need to rip the whole interior apart :/

hmmmm so that trouble shooter is for the door ecu if i skimmed that correctly (yes i said skimmed)? if i had a door ecu "code" wouldn't it set off my regular ecu thus causing some kind of code on my dash? wouldnt think it would be a stripped wire though, i wouldnt think.
most of my interior has or will be torn apart and i know how to set this off actually.... i take mine through a car wash or let it sit outside in the heavy rain

Try to seal the outside of the door window with some duct tape and hose it down real good or go through the car wash to see if that helps. The body #1 ECU is by your glove box on the kick panel. See if that shows signs of getting wet. Maybe try to duct tape different sections of your windshield and then wet down.

this trouble shooter is for the communication between ecus: body ecu #1 & #2, all door ecus, memory seat, indicators, steering wheel memory, A/C and engine. As far as I know, no code is displayed on dash when this fails, however error codes are displayed via door open indicator. And no, you don't need an OBD scanner, a paper clip will be enough - see the link I posted before.
Just an idea: this could be any door wire harness, and I mean any of them. Have you checked the grommets?

Everything that Curry mentioned is what I experienced and it was heavy rain for last 4 days. Didn't start doing this until midway day 2. My car did substain some front end damage when it had 10K miles on it, which was 110K ago lol...Windsheild is factory glass, but don't know if it was replaced in that original collision with OEM. Everything is working perfectly fine today. Im going to dig into my panels on thursday. Is this ECU located in the passenger door? Im looking to insulate the ECU from the elements. Maybe even extend wires and relocate it into the glove. Whatever needs to be done. Im not going to spend 379 on a new computer to have it get wet again.
