help .please .drivers window wont go down all others work. just one day didnt .seperate fuse?

Driver door window motors typically get used more than the others over the life of the car. With the age of your vehicle it's possibly gone bad. Check wires going to motor for voltage when switch is depressed. If voltage present then motor is bad. Sometimes you can tap on them lightly with something and get them back to working for a while but it will need replaced for it to be trust worthy.

agreed

Good one Jim. Never thought of checking it that way.

Driver side window motor works, window goes down but only comes back up half way with a scratching sound

Disconnect the negative battery cable for a minute and reconnect to reset the computer / memory.
