I realize I am new to owning a Sport Trac, and I have had mine for less than 24 hours, but it isn't without issues already. I was poking around my ST tonight (I work night shift so I am usually awake at this time anyway) looking for a way to make the rear window work. The rear window was only thing I noticed didn't work when I got it, and that is a separate issue. While I was doing that I tried to adjust the brightness of the dash lights. As I turned the dimmer switch I could hear a relay clicking a machine gun. If I leave it on any setting other than "off" the dome lights will not switch off when I close the door even after I lock it. When the sun comes up I will try to identify the relay and see if changing it fixes it. If not then I guess I need start tracing wiring or finding a way to test the switch.
