It sounds like you might have a bad window motor.
The windows are centrally controlled, if it was a relay issue you would not have any of the window working.
In order to replace the motor you will have to take the inner door panel off.
It can be done using simple hand tools.
You always want to make sure you are getting power to the motor before replacing, in care there is a short in the wire.
