ford had a recall for the cruise control you might want to take it to them and have them looked at it.... i took mine to them and they changed all kinds of stuff that was not broke but had been recalled

first, check the relay... but second, i had an 04 f150 heritage and i believe there was a recall on the cruise control unit for certain model yrs... i think it was 02-04... have your dealer check it out and they will replace it for free

The tip that connects the accelerator cable to your throttle for the cruise control may be broken. I have had that problem before. The light won't come on cause your cruise isn't engaged

I "HAD" the same problem but fixed it.

'03 Sport trac w/70,000 miles. Started around 60,000 mile mark with light flashing briefly, only engaging 1in 10 times. Also, I noticed slightly decreased gas mileage around the same time.

Cruise Control problem corrected itself when I replaced the spark plugs and wires. Owners manual reccomended replacing plugs and wires at 100K. Do yourself a favor and replace them early. They were very difficult to get out. I noticed arcing from wires to block and several areas of friction damage to insulation. Wrap new wires with sheathing and tie wraps to prevent friction problems in the future.
