Hi @ Norman Tate,
It won’t be the fuse.
Here’s the 2005 Dodge Ram wiring diagram (you didn’t state your specific year model but this is within the range selected on this page).
In Sect.8W-60 it shows the the power windows circuits for both the driver and passenger sides and they are both powered by the same fuse (IPM fuse #9) and the Power Window circuit breaker. (see also 8W-13-24)
In Sect.8W-61-3 it shows the door locks are fed by IPM fuse #28.
You would need to need to check the wiring through the driver side door lock/window switch control module to see if it was OK as the power for the passenger side comes through it.
Hopefully this is of some help
