Could be your switch panel in the drivers door. It is more than a stack of switches, and looks to be a control module.
There have been posts here concerning this. Mostly they were about loose or bad wiring. The door panel is not that hard to remove. The sealant used inside the door is a black goo which never dries.
No, I think all are wrong. The door controls panel rarely go bad.
The problem is the wire bundle that goes from the body into your driver door.
Due to the age and constant opening and closing of the door, plus the temperature changes through out the years, the wire inside get brittle and get broken.
So, you may have one or several wires in the bundle snapped somewhere along the wire between the door rubber grommet area.
I think there is some tool you can use to find shorted wires.
Nevertheless, you have to cut the wire and re-connect so that they are not shorted.
Trying to work around and between the door is a major pain.
Inside the door is okay but the wire is really tough from the joint into the body and under the dash.
It is not fun.
I know because our family van also did the same thing.
The worst case scenario is your Body computer module is toast (I forget the exact word).
I would investigate finding a used one on ebay (that's what I did when I fried it by mistake when jumping the car during a raining day). It was around $60.
It killed the dash light, rear light when head light is on (dangerous at night due to others can't see you), power window stopped. The headlight still worked, engine worked and drove fine.
It's under the foot well carpet on the front passenger side. Pretty easy to replace, remove a few plastic panels screws, lift carpet and there is right there. It's on the slanted portion.
Just pull the one in yours and find one that's kind in the similar ID range - Sedona ones do not need to go to a dealer, they are pretty much interchangeable, I think. But, i still looked for one that was pulled from a similar model and year. I think next generation ones are a different story, though.

I bought my Kia Sedona 2.9 diesel 2004 Manual from a small but well respected local 2nd hand car dealer 3 months ago. I found the gear/shift change to be quite clunky & stiff as soon as I drove...
Many moons ago I posted about a "false positive" on the temp gauge showing overheating when it really isn't.
I have finally gotten around to replacing the ECTS, however, I can not remove the old one. I have noticed on
the new one, its threads are coated in a red layer of something. I am...
I have a 2003 Kia Sedona with about 140k miles. 8 months ago I replaced the thermostat without noticing any issues with temperature gauge because the check engine code kept coming on. 3 months ago I had a mechanic replace the AC compressor and receiver drier because AC wasn't working and that...
Hi there folks!
I'm looking at possible getting a hold of a used 02' Sedona to rent out on Fluid Market. There's a really clean, low mileage one for sale not too far from me (113k miles for $2,500).
However, I haven't been able to find much on them as far as reliability goes. Are there any...
