@needadvice it wouldn't be a fuse. The fuse would not care if the motor goes up or down, it protects the motor no matter which way it operates. Since your window goes down but not up, it's not the fuse. You want to check the switch first and then the actual motor. You will have to remove your door panel etc. WE need to know if this is a Altima Sedan or Coupe (2 or 4 door)

Here is the part from the service manual that deals with the power windows. It is quiet complex. We do not know your comfort level on working on this yourself, but it gives you an idea. It can be pretty involved but it is ***NOT*** rocket science. So, it's up to you ;-)
