Thank you for allowing me to help you with this concern today and am sorry to hear that this is happening. I will have to ask you a few questions so that I can get a better understanding as to what may be going on with your Highlander.

Does the passenger side front window work from the drivers switch?

Customer: replied 2 months ago.
fronts work from driver switch
Expert:  Genchi Genbutsu replied 2 months ago.

Ok, on the drivers switch is a cancel button that doesn't allow the other widows to work, press that and then retry the other windows.

OK tried that rear window still won't work on any switch. The RR window won't work from its own switch but the LR window will work on its switch. Some forums I've found say this is a problem after a battery change and require a reinitialization but I cannot find the prosses
Expert:  Genchi Genbutsu replied 2 months ago.

The process would be to (with all windows fully up) hold down the drivers front window till it goes all the way down and continue to hold it for 3 seconds. The hold it up the same way. Repeat this for the passenger side front window and then retry the other windows. This video may help.

Let me know.

hi my name is ***** ***** I help you. we had recalls on the master switches for a few of our models so ask your dealer to check if your vehicles vin number is ***** this sure looks like a master switch issue ,all the windows go through it. and it's too low mileage and age to have a wiring problem. hope this helps good luck.

Thanks I will try that. I did try the learn routine from the dealer. It was diffrent from the one in the video. The car is to new for my maxme scanner. I would really like to see if the car can monitor the window switches.
Expert:  Peter Bagley replied 2 months ago.

the only time the scanners can monitor the windows if it has a customization mode built into the vehicle , that allows you to modify the operation of certain options to suet your needs

Ok i understand. The car is right of the truck! Maybe they didnt set up or messed up the dealer PDI right? Either way ill talk to the dealer tomorrow. Thank you
Expert:  Peter Bagley replied 2 months ago.

correct , the sales person should have walked you through all the options and accessories explaining how they worked , plus if you had any questions the service department should have any resolve for you, they can better tell you if it's just a programing issue in the customization area or not .Being that new I'm sure it's something simple like that. delivery communication with you would have eliminated this when you picked up your vehicle. good luck and let us no how you make out.

I updated my scanner and was able to roll up and down the front windows with it, but not the rears. Scanner said it lost communication with bcm b. The dealer got me fuse locations and a little wiring. Turned out the fuse for body control module B blew. It is one of the three 30A fuses on the side of the underdash fuse box. I replaced it with a 10A and got it to blow by rolling up the real windows and holding the switch. Then replaced it with a 30A and it didnt blow. Any chance a 30A cartridge fuse be made bad ?
Expert:  Peter Bagley replied 2 months ago.

for operating the windows it should be at least a 20-30 amp, are the windows operating now ?

Expert:  Peter Bagley replied 2 months ago.

you said this vehicle is right off the truck new? then they obviously miss something on the PDI, is that the only thing that doesn't work? the cancel switch on the master switch would kill all other windows but not the driver's it's just a safety feature. Did you ask if your vehicle has the customization feature in it's ECU ? THAT'S A VERY POSSIBILITY IT'S SET THAT WAY ONE OTHER QUESTION, DID THEY WORK BEFORE YOU HAD THE AFTERMARKET REMOTE INSTALLED?
