3 windows other than driver's side
3 windows other than driver's will go up with drivers's switch, but not with the switch at each door. Is there a fuse for that?
This goes up to 2000 for Crown Vic and Marquis but it may be same. Fuse 14. click to enlarge
Check to make sure the window lock button is actually working as it will lock out the all but the drivers door window switches when activated, safety concern for children so they could not roll down the windows via the door switch.
Change the Master Switch. The drive's switch. The one that gets used the most and gets rained on occasionally.
