We have a 99 F350 Crew cab v10, we are having problems with our power door locks and windows. for a while neither the inside buttons or the remote would unlock all the doors, it would only do the driveer door and left rear door. and all windows would work find. now the only lock that works is the driver door and the front passenger window doesnt work. we have already tried a new battery in the truck, but it didnt help. there arent any electronic mods either. anybody have any ideas for us? thanks

How easy is it to change one of the modules out?

Once you find it, very easy.

I would look at the door controls. The electronics controls for the windows have carbon contacts that wear out and loose connectivity with use. (just like your nintendo game control pad, after so much use the buttons stop working - but it is only because the carbon contacts have worn out.)
The window switches are easy to remove and you can take them to your dealer and buy a replacement.
