  PINPOINT TEST H: FLASH CODE 3 - DEACTIVATOR SWITCH CIRCUIT FAILURE
• CONDITIONS DETAILS/RESULTS/ACTIONS H1 CHECK THE DEACTIVATOR SWITCH CIRCUITRY
  Speed Control Servo C122
  Measure the voltage between the speed control servo C122 pin 9, circuit 307 (BK/YE), harness side and the speed control servo C122 pin 10, circuit 57 (BK), harness side.
  
  • Is the voltage greater than 10 volts?
  Yes INSTALL a new speed control servo. REFER to Speed Control Servo in this section. REPEAT the self-test.
  
  No GO to H2 . H2 CHECK DEACTIVATOR SWITCH POWER
  Deactivator Switch C1025
  Measure the voltage between the deactivator switch C1025, circuit 10 (LG/RD), harness side and ground.
  
  • Is the voltage greater than 10 volts?
  Yes GO to H3 .
  
  No REPAIR the circuit. REPEAT the self-test. H3 CHECK CIRCUIT 307 (BK/YE) FOR AN OPEN Measure the resistance between the speed control servo C122 pin 9, circuit 307 (BK/YE), harness side and the deactivator switch C1025, circuit 307 (BK/YE), harness side.
  
  • Is the resistance less than 5 ohms?
  Yes INSTALL a new deactivator switch. REFER to Speed Control Deactivator Switch in this section. REPEAT the self-test.
  
  No REPAIR the circuit. REPEAT the self-test.

If cruise control main light comes on but you cannot set a speed (no set), you could have a bad brake pedal switch.
(If the cruise control light comes on, chances are that it is NOT a fuse issue).
Some vehicles have two switches (one for brake lights and one for cruise control cancel) and others have a multifunctional, single switch.
The function to cancel cruise control is very sensitive so it only takes a small movement of the pedal to cancel cruise control.
You can try lifting on the brake pedal while trying to set the cruise, but this does not alway work. Replace switches are pretty cheap (less than $30) and pretty easy and quick to replace.

My guess is one of the following
The power not going to the cruise servo
Cable not holding
Servo failed
Switch failed

Usually mounted on the intake manifold or the fender.
You should be able to follow the cruise cable from the throttle body.

Sorry we have no parts locator service here.

I have a 2001 lincoln an when i try to set the cruise the light will flash but it will not set ?

Fuse number 1 (15amp blue fuse) located under the dash is the primary fuse for the cruise control servo...check that first...Also, if i recall correctly there was a mandatory recall notice issued in 2005 for this model related to cruise control failures. Check with your local Lincoln Mercury dealer for more information. You will need your VIN number to see if the repairs on your vehicle have been made. Good luck, i hope this helps.

If the cruise lamp comes on and the cruise does not set i would advise inspecting the cruise cable and make certain it is not broken, if ok the the servo has likely failed.

Ford has a recall on yours if a tilt wheel is an option in your truck
