2000 Buick Park Avenue front night lights dont turn off whe

My car got stack in the water because of my foult, so after some funnky moves of the two rear windows by their selfs what I had then available was:
I had everything(lights, signals atc, ) exept the two rear windows were not moving up and down. But the rear right window was down and driving in the rain was not a pleasure, so I decided to bring the car to a repair station. I said to them I just want to bring the window up(talking about rear right side), ok thay said we will power the motor and if is good it will bring the window up. 5 hours later I picked up the car, the window was up as I wanted, I drove home. But when I parked at home I saw the parking lights and running lights on the rear of the car were not on exept the only one spot on the rear left corner. I went back there where I came from and those guys were not responsible at all, they said oh you have wiring problems, oh yeah I said I know that but when I came hare there was not such a problem, thay tried to find something on the fuses but didnt, so I asked the guy, when you pawered up the window's motor did you disconect the motor from the rest of the car? They said yes but I'm sure they didnt, so it was my bad luck going there. The ironik of this is that the rear left window started working properly(car started drying, good weather)So I dont have rear lights no matter is day or night exept one spot on the left, and I have front running lights. When is night I have only front night lights which doesn't turn off when I shut off the engine(so I have to remove a fuse not to let the battery drained)thay turn on when it gets dark while driving. What I noticed was a wet rear window modul under the right rear seat, which I replaced. Please it was very long thing to read but help me what to check and where are the locations for the rear window, for the front night light that stay on when engine is turned off, and for the rear lights that are off all the time exept one spot on the left.
