My Cruise Control has suddenly quit working. The green light in the button on the dash will not come on and it will not engage. (Makes me think there is no power going to it.) I thought that it may be a blown fuse but when checking the owner's manual I could find no fuse for the cruise control. I was told to check all of the fuses in the engine compartment and all of them SEEM to be good. I was also told to check all of the bulbs and all of them seem to be good also. I was going to wait until my tax refund came back and take it to a repair shop. First tried Haynes manual and all they said was to check fuses. Found you and decided to give you a try next.

If the light is not coming on when you press the button then that is most likely a switch issue.

What I would do is go to the cruise control unit and press the button and see if you have voltage getting to the unit. If not then the switch or the clockspring is the issue.

If the light comes on but the cruise does not engage then by far the most common cause is the servo has failed. Basically this is the motor that holds the throttle cable in place and will actually move it when needed to keep the proper speed that you set.

This could be one of two reasons. Either the servo failed or the servo cable needs to be adjusted.

I am attaching both processes below on how to replace it and adjust it, plus the wiring diagram to help with this testing.

Please let us know if you have other questions.

Thanks
