It can be faulty cruise control switch. If the switch is replaced, then it can be wiring issue or faulty cruise control board. But as the switch is replaced, get the voltage at the switch tested to confirm the switch is actually receiving voltage. If no voltage received at switch power supply wire then, apply external 12 volt power to the cruise control switch wire and then see if cruise control comes ON. If yes, then you know wiring is issue.

SOURCE: how to fix the cruise control - won't hold speed

It is vacuum operated. It may currently be disconnected from the carburetor'throttle body linkage.

On the off chance it is connected, it likely has a hole in the diaphragm. So it may be disconnected at the vacuum line to the intake manifold.

There is also a vacuum dump switch which might be stuck open, damaged, or just out of adjustment which is normally pinched off until the brakes are applied and the switch is supposed to dump within the first inch of travel of the pedal. This is a mechanical override of the cruies control, and the brake light energy is supposed to release the control when the brake lights are energized.

There is also a magnet and sensor down either on the transmission speedometer gear housing,where it enters the transmission or on the driveshaft. If the magenr is not there, there is no speed pulse reference for the control to operate from. So it has no reference it can maintain.

It is not a sophisticated system, and it is prone to leaks after 23/24 years.

You can hear the dump valve if it is open, you can hear and see the diaphragm on the cruise control to see or hear if it is damaged when the hood is open. With the right meter, you can ascertain if the magnet is still present in the spot it is supposed to be once you locate the connector for the sensor- it is a hall effect switch usually.

You already know the electrical portion of the system works, so the problem is largely isolated to a vacuum leak or a sensor of unit is still connected. Normally the vacuum unit sits on the inner fender on either side.and the control cable arcs over to the transmission linkage side of the carburator or throttle body, it has one wiring harness connector and one vacuum connection and the cable to the carb, and usually only 2 bolts holding it down.

A wrecking yard might be a source for a good unit used, New old stock may still be in the system although likely aftermarket with the nationalization of GM.

2001 F-150 cruise control stopped working. Already checked the fuse and it's good. What's next


really tough to do on the net but first we need to know about any codes...

Hold speed control OFF button, and turn ignition switch to RUN position. CRUISE indicator should flash once to indicate successful entry into self-diagnostic mode. If CRUISE indicator does not flash, start procedure over. If CRUISE indicator still does not flash, repair system by symptom there might be some switch concern

If CRUISE CONTROL indicator flashes once followed by 5 additional flashes, replace speed control servo/actuator.

Release speed control OFF button. Within 5 seconds in entering self-diagnostics, press speed control ON button. Press remaining speed control buttons in the following sequence; ON, RES, COAST and SET/ACCEL.

As each button is pressed, CRUISE indicator will flash.

Wait until indicator light goes out, then press next button. After sequence has been completed, indicator light will flash to indicate test passed or failed. With the codes we can then better diagnose your concern

Immediately after static test has passed, actuator performs a dynamic test by automatically operating throttle .04-.40" (1-10 mm). Observe throttle movement to witness any sticking in cable or linkage. Ensure throttle returns properly. Turn ignition switch to LOCK position. If self-diagnostics do not pinpoint fault there is more we can do but tough over the net

Cruise control will not turn on. light on dash use to come on. cruise will not work. checked fuse it is ok


Did you have the recall for the cruise control done ?
recall 05S28. Description: Speed Control Deactivation Switch.

It could be the fuse in the recall harness is blown.

Try the Cruise Control Self test :
----------------------------------
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).

— 3 flashes - deactivator switch is open or circuit defective.

— 4 flashes - vehicle speed signal is out of range or circuit is defective

4. Immediately (.25 second delay) after the static test, the speed control servo does a dynamic test by automatically actuating the throttle lever from 8 mm (0.315 in) to 12 mm (0.472 in) of travel from the idle position. During the dynamic throttle pull, observe throttle movement to witness any binding or sticking of the speed control cable and correct connection of speed control cable to throttle lever. Make sure the throttle returns to the idle position.

5. Return the ignition switch to the OFF position and proceed to the Symptom Chart.
----------------------------

If the Cruise Control does not enter self test, the fuse in the recall harness ( if done ) is most likely blown and needs to be replaced.

I have a 2008 Honda CRV and for the life of me I cannot engage the Cruise control- I press the Cruise Button on the right of the steer wheel and nothing happens - nothing Help anyone ? Tks Nancy


The cruise-controls have 2-buttons that must be activated before it gets the car going when you remove your foot off the gas-pedal.
The cruise button is essentailly a switch that turns 'on' the cruise servo-motor that tells the sytems that you wants to use it, so it gets ready.
There are other three switches on the right-side of the steering wheel namely: resume accel; cancel; set decel.
To get your car to cruise: you must steady your speed and foot on the gas-pedal. You cannot just press the switches and expect the car to cruise. It takes about two-to-three seconds for the system to respond to a set cruising speed.
How to do it: accelerate to a speed of about 30-mph. Press the 'cruise' button on the dash first. Next you press 'set decel' button. This will turn 'on' the cruise control light on the instrument panel. Then wait a second or three and you would feel the cruise engagement. Any touch on the brake pedal will slow down the car and turns the cruise off. The 'cancel' button turns off the cruise light on the instrument panel.
If you hit the brake-pedal at any time for any reason, and you would like to continue cruising again, simply press the 'resume accel' button.
The cruise system works in conjunction with the braking system of the car. So all major parts of the braking system must be in good condition, otherwise the cruise system could shut off itself.

"Cruise" on a 5-speed '00 Hyundai Elantra


I have this same car. The place you set speed control is on the windshield wiper switch on the right side of the steering column. The button with the indicator light has to be pushed in order to use the cruise control but just because the indicator light is on, it does not mean the cruise is on. Hope this helps a little. If you need more info and someone else doesn't answer more eloquently.. I'll check back and try to give you more info. :-)
