AP500 Cruise Control cable actuator version. Is it possible to have the AP500 only work on the first half of the throttle opening?

Maybe by a physical actuator cable stop near to the carburettor? Would the AP500 think it was at full throttle when the cable was prevented from further movement? Would it burn the actuator motor out?

SOURCE: Cruise control stopped working at about 70k.

Check for a broken plastic piece under the hood on the throttle control. Top, Back right of the engine. Probably will see the cruse control cable sitting there disconnected.

Is the vehicle a four cylinder or V6, either way if what they stated to you is indeed the only problem, there are a few Mcgyver options open to you for far less than what they quoted. The lever itself is only a metal arm with a protruding ball type fitting for the cable. The leftmost cable is for the cruise control. I take it the bushing on the cable is worn or the rod itself has the lip damaged. Either way from in the hood snap the accelerator linkage a couple of times and watch how the cable comes off. A small tie strap between the cable and the end of the rod will probably solve your woesmacvernal.jpg

Cruse control on 2008 Chevy Suburban stopped working. Changed the brake lamp switch (twice). Any suggestions? Where is the fuse located?

This is a computer controlled system (BCM) supply's power to switch .Voltage is supplied to the cruise control switch via the steering wheel control switch reference voltage circuit supplied by the BCM.
The following are the main components of the Cruise Control System:
• The accelerator pedal
• The stop lamp switch
• The body control module (BCM)
• The cruise control switches
• The engine control module (ECM)
• The throttle actuator control (TAC) motor
• The vehicle speed sensor (VSS)

Taking your vehicle to a quailfied repair shop would be your best option . Using a factory scan tool to view input data from switches and sensors is the only way to diagnose the cruise control on your vehicle . Just replacing parts does not cut it .

The body control module (BCM) monitors the signal circuit of the cruise control switches. The BCM relays the cruise control switch status to the engine control module (ECM) via the GMLAN serial data circuit. The ECM uses the status of the cruise control switch to determine when to capture and maintain the vehicle speed. The ECM monitors the vehicle speed signal circuit in order to determine the desired vehicle speed. The ECM uses the throttle actuator control (TAC) motor in order to maintain the vehicle speed. For further information on the TAC System, refer to Throttle Actuator Control (TAC) System Description .

This is not a fuse problem !!!!!!!!!

You probably don't know what GMLAN serial data is ,do you ? It's GM 's version of C.A.N. How to Diagnose Controller Area Network CAN

Cruise control is not working

Cruise control directly control the electronic throttle body.Since version is electromechanical ,throttle pedal is directly connected to the throttle body through a cable and cruise control is achieved by way of a servomotor that sucks in that cable and holds it in place.First you have to inspect the electrical switches and clear it.You should also check fuses related to the system anf if you have multimeter check that wiring also.

Fuse is good but cruise don't work

Visual Inspection Chart Mechanical Electrical
  • Inspect and verify that:
    • actuator cable is attached to throttle lever bracket ball stud or nailhead
    • actuator cable is adjusted properly without holding the throttle open or increasing idle speed.
    • throttle linkage operates freely and smoothly when connected to the actuator cable and speed control servo.
  • Verify proper horn operation.
  • Verify stoplamp operation.
  • Check fuse junction panel Fuse 15 (15A), Fuse 30 (15A) and Fuse 7 (15A), 16 (20A).
  • Inspect and verify that:
    • connections are complete with no loose wires or terminals.
    • wiring is not broken, shorted or corroded.
    • wiring is not misrouted.

What causes cruise control to work when truck cool but will not once the truck warms up?

suggest checking cable on accelerator throttle arm in engine bay where it connects from cruise control to accelerator throttle arm on engine. Thinking if it is loose it may get looser when hot.
Check connectors on electronics in engine bay on cruise control.
Check sensor for speed. Is it ignition maybe a scotch lock connector that expands with heat and cruise control looses sensor for igition pulses. How does it sense speed ?
Is it magnets on the drive shaft maybe the Hall efect transducer is close to exhaust pipe under car and is being affected by heat.
Is it front wheel drive ? check for a pulse sender on speedo cable in engine bay maybe this is getting cold.

Check cruise control cable is oiled adequately in cable sleeve .

check vacuum connector is ok in engine bay also ?

Where is the fuse for cruise control in a buick century and what are some reasons cruise control may not work?

Need to know what year the car is and what engine, it makes a difference. Possible causes could be a fuse, cruise ECU, vacuum line(if vacuum actuated), cruise servo(if electronically actuated), cruise switch, wiring, cruise cable. There are lots of possibilities, but if you can tell me the year and engine size that will help.

Cruise control stopped working

Check the cable for the cruise control that leads from the actuator to the cable end located on a wheel that controls throttle. If this cable is broken on the driver's side, then it will not work even if the cruise control is engaged according to the dashboard's driver information center.

U try to set cruise it dont come on also speedometer dont work

Fix the speedometer cable or VSS (vehicle speed sensor) circuit before diagnosing the cruise.

The cruise control is a separate system that uses speedometer information to adjust the throttle up or down depending on the speed detected.

Also, the actuator cable for the cruise control could be broken.

But, I would check the speedometer problem out first.

Cruise control went out on my 2005 ford taurus and my accelerator gets stuck at times. Should I replace the cruise control?

This is a dangerous defect. What you want to do is isolate the Cruise cable from the Throttle mechanism. Then get the Cruise cable away from the Throttle so it can not jam the Throttle accidentally.

With the engine OFF use your hand and move the remaining Throttle mechanism and feel for sticking or roughness in the control. If you feel binding, start removing the connection of the Throttle cable and work your way through all the moving parts like a Butterfly flap on the Airhorn, the TPS (throttle position sensor) and so on until you find out what is rubbing.

It is possible that the Cruise was disengaging because the Throttle parts were binding. If disconnecting the Cruise eliminates the sticking throttle, then all the problems came from the Cruise control cable or the Cruise Box. Once you have made a thorough check of the Throttle you can blame the Cruise for your problems and replace the parts.

98 chevy k1500 cruse control


Appreciate the "Ask Me".

To my knowledge, Cruise Control would be relatively difficult to diagnose without a scan tool attached to the control module to read the error codes. Additionally, car versions in my country seldom have such a device since our roads are narrower and travel distance is not that great.

Though most known causes are:
  • the connector to the module;
  • loose brake pedal/switch;
  • loose clutch pedal/switch (for manual transmission);
  • vacuum line to actuator (most likely), vacuum actuator, diaphragm, control valve.
Other possible components to check are:
  • the control module itself (bolted to the firewall);
  • control cable or linkage;
  • speedometer sensor;
  • steering wheel controls switches;
  • throttle position sensor.
As posted above, quite a number of possibilities. Any other indications, speedometer OK; abnormal throttle responses; abnormal idling, brake light always ON, slack in the accelerator/gas pedal? Was it cutting in/out before? Was there any recent repair work done on the engine before the cruise control cut out?

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards. Thank you for using FixYa.
