Default Glad this sucker doesn't have an eject seat. Elect-tree-cow gremlins

Yes I can see this car (2000 SSEI) with an eject seat "Hey Honey hit the trunk button in the glove box please" and WHOOOOSH! there I go through the sunroof

Taking my son to school today and was wondering how my back window rolled down during the night but rolled it up (Thinking I KNOW I didn't leave that down because "the cat" would be making herself at home there) anyhow so here we are driving down the road when my alternating right and left rear door ajar bells and dash warning starting doing a symphony for us. Both were shut tight. Then I went to hit channel two on my stereo presets. Station changes and also ROLLS DOWN THE RIGHT REAR WINDOW ha ha. My son and I just looked at each other with a "Did you just see that?" ha ha On way home the drivers rear window rolled part way down and then pass rear again all the way Might explain why the alarm went off other night too

I had a thread on some electrical issue elsewhere but I think I best start a new one here since this is new stuff.

A quick history. Although it runs and looks great, the car has 15 error codes (can post them later but several due to a bad wheel speed sensor) and the car has had massive water leaks into the interior (all the typical spots,sunroof,trunk etc) I think I have now stopped 90% of them after I got tired of the mold and interior of windows wet all the time.

I have not pulled the seats out and looked under the carpet at the harness under there yet as suggested but what I wanted to ask here is where is the box that controls the doors and windows?

Is it under the back seat (battery box and rear floorboard were always filled with water until installed a drain in bat box and now have fixed the actual leak). If so I have a can of electrical dry but as this car sat for a year or two before I got it we may be talking corrosion rather than simple moisture issues.

I just can't afford to be driving the kids to school and the car catch on fire or ground out and fuse together. Should I put out a wanted ad for some of the electrical components and just swap them out regardless, and being still new to computerized cars which one should I focus on please?

Thanks for taking the time to read this and help.

the doors have modules in them that talk to each other via a com bus like a computer network. if you have water and corrosion issues from the water it will cause all this havoc. the bus wire is what you want to be chasing not the controlling modules. there are way to many problems for it to be that many individual modules failed.

most all the bus wires are purple and having never worked on your car i would pull the front seats and or carpet and look for a wad of purple wires and take the wad appart and look. the reason i say that is there should be an output around there for the seat module and possibly where it breaks off for the rear integration module

sorry for the misinformation, this is one that has a seperate network for the doors only. the driver door module is connected to the cars network so im not sure if the window problem could be on the cars network or the door one, but i do remember others with non functioning door problems and it was the same area i was talking about but the wires are tan/white

Thanks for posting all of that as well as the suggestions, Justin.

Going to be forced to do this soon. Interior lights were coming on tonight driving down the road,both rear doors ajar dinging. Windows behaved themselves and seat did not start adjusting on it'* own like it did earlier today.

Yep time to pull some seats,inspect some wires and grounds and resolve this mess.
