My drivers window is the only one that has the auto up/down...
You can add Auto Up/Down to the passenger side by swapping in a motor from a Navigator since they come with it standard for both front windows. You'd also need to replace the driver's master window switch (not sure about the passenger switch) as the wiring is slightly different. You might need to make some minor tweaks to the wire harness as well.
As for the rear windows, on other Ford vehicles there's a door module in each door that directly controls the windows, thus the option of operating all of them remotely. We don't have that option -- even with Auto Up/Down since that feature isn't controlled by a module in our trucks but rather by the door motor itself.
Now, if you wanted to get
really ambitious you might be able to install a Ford door module and use it to control your window motor (which you'd have to swap), but you'd also have to deal with the network signalling needed to control it. For example, the switches in vehicles with modules look the same as ours but they don't switch any power. Instead, they're LINbus units that transmit a signal over a single wire to the module.
