Drives Door Power window

My drivers door power window works when it wants to. I do not thinks it is the switch nor the motor. It works great in the morning window goes up and down, But when I move the car the window will not go down any more, it all ways will go up. Some time when I stop some place and come backout to the car the windows will go down, but as soon as I move the windows will not go down any more

Definately a wiring problem. I'd start with the switch connections.
Somewhere recently I've seen a post where the switch was a culprit in this type of problem.
