Faulty Cruise Control

02 5.4L

Cruise control will not engage. Switches work light flickers when pressing accelerate.

Any idea?

Check to see if your brake lights are working. On some cars, if a bulb is burned out, the cruise control won’t activate. Also, if the brake lights are stuck on, the cruise control won’t operate. I had this happen on a Ford Tempo that I owned. I was on the interstate and the cruise wouldn’t work. Motorists kept honking at me as well. A new brakelight switch cured this problem.
