I have a 2005 Ford SprtTrac XLT wit h around 100k miles. The cruise control doesn't come on. When you press the "ON" and "CST" switches indicator flashes on the dash so I guess it means its getting power. The repair attempts to repair the cruise control included replacing the switches on the steering column twice. thought maybe got a bad set and replaced the steering column switches twice. Checked the fuses and there are no blown fuses. Replaced the brake pedal release switch and the cruise sensor switch on the master cylinder. The reason this feed is titled "No cruise or 4wd and need wiring diagram" is because the 4wd switch will not illuminate and engage the 4wd system. I'm wondering if anyone has a wiring schematic for the cruise and 4wd systems for a 2005 Ford Sport Trac? I'm hoping a wiring diagram will point me in the next direction to proceed, I'm at my wits end.
