Just today, the window on the drivers was stuck rolled down. I was driving with the lights on the 190D 2.5; I lowered the window for fresh air. Later in the morning I turned the lights off and the window would not go up or down. This evening, when I turned the lights on, I tried the window again and it worked.

With the lights on, the driver's window works. Lights off, no window. This only affects the driver's window. I'll be checking fuses and for shorts tomorrow.
