Speed control inoperative suddenly on 02 Ford Galaxy diesel . I commute from S. Wales to Portugal , often by road. I arrived here in Portugal in January.A few weeks later , without warning , whilst driving along a motorway , I engaged the speed control but nothing happened. As there is`nt a manual available for the later model ,I looked at the earlier manual which I have , but its totally different to my model.Fuses are all ok , can`t find a relay mentioned in my handbook. I`m due to drive back to UK in April , its 1400 miles on my right foot ! Grateful for any ideas , and I`m no auto leccie either !! Bob.

are the brake lights working are their any codes having any type of brake problem switch/lights etc wont let cruise control work check wiring and fuses

The pressure switch on the master cylinder has nothing to do with the cruise control . The pressure switch as you call it is not a pressure switch at all . Brake fluid level sensor . The brake switch is under the dash on top of the brake pedal linkage (arm) .
Speed Control The vehicle speed control consists of the following components:

• speed control servo (9C735)
• speed control actuator cable (9A825)
• speed control indicator lamp
• speed control actuator switches (9D743)
• brake pedal position (BPP) switch (13480)
• deactivator switch
• anti-lock brake control module (2C018)
• clutch pedal position (CPP) switch
• Self-Test Diagnostics
  WARNING: This test is a key on engine off (KOEO) test only that is conducted in PARK only with parking brake fully engaged.
  
  • Enter Self-Test Diagnostics by depressing the speed control OFF switch while turning the ignition key ON, making sure the engine does not start and is not running. The speed control indicator lamp on the instrument panel will flash once to indicate that the speed control module entered the diagnostic mode.
  NOTE: Five additional flashes at this point indicate a defective speed control servo. Release the OFF switch.
  
  • Release the OFF switch.
  • NOTE: If the ON switch is not pressed within five seconds after entering the diagnostic mode, the module times out and the procedure must be started over.
    Press the remaining switches in this sequence: ON, RSM (resume), CST (coast), and SET/ACCEL. The speed control indicator lamp will flash as each switch is pressed. Press each switch in the sequence immediately after the light goes out for the previous switch.
  • A lamp flash with the last button (SET/ACCEL) indicates that the STATIC test passed. If the lamp does not flash with the last button and there are no additional flashes of the lamp, the switch is defective. If the lamp does not flash with the last button, and additional flashes occur, follow the chart below for trouble codes:
    • Two flashes - Brake pedal position (BPP) switch is defective, circuit is defective, or brake pedal is applied; clutch pedal position (CPP) switch is defective, circuit is defective, or clutch pedal is applied.
    • Three flashes - Brake deactivation switch is open or circuit is defective.
    • Four flashes - Vehicle speed signal is out of range or circuit is defective.
  • Immediately after the static test has passed, the speed servo will then carry out a dynamic test automatically by actuating the throttle lever from 1mm to 10 mm of travel from the idle position. During the dynamic throttle pull, observe the throttle movement to witness any binding or sticking of actuator cable, correct connection of actuator cable to throttle lever, and make sure the throttle returns back to idle position. If incorrect connection and/or binding or sticking of actuator is observed, go to the Symptom Chart. If dynamic pull at the throttle body is observed, Go To Pinpoint Test A .
  • Return the ignition switch to the OFF position and proceed to the Symptom Chart.

There are a few more thing's involved then just fuse's .

Central junction fuse box , behind left side or right side of the dash panel ! Fuse's are - F2.5 - 5amp , F2.11 - 10amp , F2.24 - 15amp , F2.16 10amp .Do you have steering wheel controls ? These controls go through the clock spring inside the steering column ! They break also , but you mite have some other signs ,like air bag light lit on the dash . Could have bad control servo module . You can go to www.bbbind.com for free wiring diagrams an fuse box lay outs !

Sorry no ideas here ,other than get a diesel vehicle for towing as you couldnt afford to run this vehicle here in europe at our fuel prices ,the diesel engine is cooler running so no problem with manifolds but your cruise should not be affected buy a blowing exhaust manifold the only thing affected by this would be your emmisions though as the lamba sensor will not be reading correctly which could cause more fuel to be burnt as it will read a weak mixture .I know nothing about the cruise on this vehicle as not many vehicles use it here in europe ,the roads are too short between the bends and too many vehicles on the road try driving through paris or london

Check oil level in gearbox.

Sounds like a computer issue, need to test with diagnostic like snap on, garage or dealer has these.

Hi, check here for free Ford Manuals:

Good luck.

look for block return lines- air leak in suction lines -block fuel line or filter - defective injection pump -inoperative glow plugs.

From under vehicle, follow exhaust down from engine, eventually you'll see a piece about 3-4" long sticking out side of the exhaust with wire(s) going to it.
