I have a 99 Sentra and have not been able to get the power windows to work for some time now. I've checked & replaced the fuse under the hood and in the car. I've got a new window/lock switch as well. Still, the windows (all 4) do nothing. The power locks do still work. There was nothing particular that caused the problem, just one morning they wouldn't work anymore. Wondered if anyone had any suggestions here. I'm thinking it might be the relay, but I don't know where it is. Thanks for any help in advance.
