OK let me just start off by saying I'm pretty good with cars. I can fix anything, but this one has me stumped. I have tried replacing the window regulators, the window switches and the front main driver switch. I bought a 2014 maxima S with only 27,000 miles for my kids first car. It had a rebuilt title, but over all very clean. I noticed the one door on the rear that was replaced with a used one is probably from an SV model so I even went to as far as replacing the door wiring harness from an S thinking that would fix it as it has a different part number. But what is also odd is both rear windows don't work. And looking at the passenger side rear door it is definitely the original one. I've checked all the fuses in the car in the dash and hood and there is not a fuse or relay for the power windows at all. The front windows work fine. So anyone else out there have any clue what to do if I have replaced the door harness, replaced the windows regulators and the switches and checked all the fuses. Everything else in the car works perfect, but rear windows are not functional. The power door locks work fine.

 

You dont mention any voltage readings, just parts so i am going to guess you have the wrong master switch or the lock mehanism is on. There are different swiches for sv vs S. Got any voltage readings for us?

 

I did try a new master switch. That was the first thing I tried because I’m aware the S models don’t have the auto down in the rear so I bought the switch that has no A on the rear window switches.

 

The SV version of the Maxima came with Auto Down switches, but only for the front windows. At least that is how my SV Sport is equipped.
