The 4ws on my 2003 5.4 L does not work. I reviewed a number of videos on checking or replacing the vacuum solenoid located on the passenger side of the vehicle at the firewall. In those videos there were two (2) solenoids side by side. In my vehicle it appears as though there is only one. The guys at car quest looked at it and didn't raise any flags. Is there supposed to be two solenoids or one on a 2003 Expedition?
