My cruise control does not work on my 2003 Ford Focus

With the car turned off and the battery disconnected, root around under the dash and find the wiring harness that comes down from the steering column. You may have to remove a dash panel or two to get at it. It should be connected to the car's main wiring harness with a plug of some sort. Disconnect the plug.

Using a multi-meter set to test continuity, test pairs of pins in the connector from the steering column, pressing the CC switch with each pair, until you find the pair that come from the CC switch.

Isolate the wires for these two pins behind the plug and scrape away a tiny bit of insulation with a knife blade, being careful not to cut through the wire. Test the wire pair again to be sure you've got the CC switch wires.

Cut the wires, leaving several inches of wire above the plug to work with. Using a good quality crimp connector (or soldering, if you know how and have the equipment), connect the two wires you just cut loose (the two coming from the plug, not the steering column).

Make sure there are no bare wires *anywhere* when you're done. Cover everything with heat shrink tubing or electrical tape, then use a tie-wrap to bind all the wires together again. Return the wiring harness to where you found it and re-install any dash panels you had to remove.

Reconnect the battery and go for a drive. The CC switch will be totally out of the circuit, but your CC should be permanently turned on.

Now here's the fun part. You'll have an extra momentary-contact switch on your steering wheel that's not doing anything. Just think of the possibilities... You could use it for an auxiliary air horn like on a semi-truck, or you could wire it into your brake lights so you could screw with tail-gaters without actually stepping on the brakes. Look for the switch somewhere on your brake pedal assembly and add two wires from the old CC switch to the contacts on the brake pedal switch.

The cruise control should have a fuse in the interior fuse block, and a larger fuse and/or relay under hood in the relay center block. Test them with an automotive test light (You can purchase these for anywhere from $5.00 to $50.00 depending on the quality you want and the place of purchase).

If you find a bad fuse or primary fuse, obviously those need to be replaced. Relays can't be tested readily using the light. Unfortunately the simplest method for finding out if a relay is bad is to replace it. The relay for that cruise runs between $15.00 to $20.00 depending where you purchase.

Let me know how it goes and we'll see what more we can do!

Try pulling up the brake pedal with your foot,Sometimes your brake doesnt come back all the way,and the brake switch keeps the cruise from working.Also,check the fuse.If those answers dont help,It could be the swith itself is bad.Those can be bought at a parts store.

Did you have the recall done on it ?
recall 05S28. Description: Speed Control Deactivation Switch.

It could be a blow fuse in the recall harness, if you did have it done.

Try the self test, and see what the results are. If you do not get it into self test mode, it could be the fuse in teh recall harness that is blown. The 1st revision of the recall harness was an inline ATM fuse, not sure if the revision 2 was the same. If that fuse is blown, the switch is leaking, and should be checked.

Self-Test Diagnostics

WARNING:
This test is a key on engine off (KOEO) test only that is conducted in park only with emergency brake fully engaged.

1. 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 on the instrument panel will flash once to indicate that speed control module entered the diagnostic mode. Five additional flashes at this point indicate a defective speed control servo. Release the OFF switch.

2. Press the remaining switches in this sequence: ON, RESUME, COAST and SET/ACCEL.

If the ON switch is not depressed within five seconds after entering the diagnostics mode, the module times out and the procedure must be started over.

The speed control indicator lamp will flash as each switch is depressed. Press each switch in the sequence immediately after the indicator light goes out for the previous switch.

Note:
There will be a slight delay when the last button is pressed and the lamp flashes.

3. 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:

— 2 flashes - BPP defective, circuit is defective, brake applied, CPP switch or jumper (if equipped).

SOURCE: how do i use cruise control on focus

The two left buttons on the left turn ON/OFF the system so that you can use the three right buttons to use the cruise control.

Once you turn ON the cruise, accellerate to the speed you want to travel. Once you reach the cruise speed, press the middle (set) button and the system takes over. As soon as you press the OFF key on th left, your car will coast / de-accelerate. ... or , if you tap on the brake pedal or press the brake pedal to stop, the cruise control will dis-engage.
WARNING
Before you get into traffic, test the use of the system..
Also, the system may not be working, so it is important that you test it before you use in traffic.

I use mine 90% of the time, even in everyday driving, not just on the highway.

Testimonial: "Haven't tried it but i think it will work. THANKS"
