What are the problems with a cruise control system?
by Paul Vaughn. The most common problem with cruise control systems is failure to engage and failure to maintain a set speed. Depending on the year and model of the vehicle, special tools such as a volt meter and vacuum tester may be needed for diagnosing the problem.
Where is the fuse box on a cruise control?
Locate the fuse box under the driver’s console. It has a plastic cover that can be removed . Check the inside diagram to determine which fuse you need to check. Probe both sides of the fuse. If one or neither lights the test light, the fuse is defected and replace.
Where can I buy a new cruise control?
Check for a vacuum leak at the servo. If the results of these checks are satisfactory, the controller is usually defective. Buy a new part at your local parts store or dealer.
What to do if your Cruise Control is leaking?
Replace the hose if leaking. Use the digital volt ohm meter to check the resistance of the servo solenoid windings. Check your service manual for the correct readings. Check for a vacuum leak at the servo. If the results of these checks are satisfactory, the controller is usually defective.

What to do if your Cruise Control is inoperative?
Apply vacuum using the hand held vacuum pump. If the servo fails to hold vacuum, replace it with a new part. This part can be purchased at your local part store or dealer. If both tests are good, this means that the cruise controller is inoperative and must be replaced. This part can also be found at your local parts store or dealer.
How does an adaptive cruise control system work?
Adaptive cruise control systems, sometimes called “smart” cruise, use radar or laser detection to maintain safe distances from vehicles ahead. Some adaptive cruise control systems merely reduce engine speed to maintain distance, but some of the newest adaptive cruise control systems can also engage the brakes to slow or stop the vehicle.
Why does cruise control not work when brake light is blown?
Brake Lights – In some systems, cruise control is disabled when a brake light is blown. Aftermarket lighting, such as LED brake light conversion, might trick the CCM into thinking a brake light is blown, as LED bulbs draw less current than incandescent bulbs.

Why is the cruise control not working on my car?
Spiral Cable – Many vehicles mount the cruise control switch on the steering wheel. A faulty spiral cable may have an open circuit, preventing the switch from contacting the CCM. Control Switch – If the internal contacts wear out, the cruise control switch may not be able to contact the CCM.
