Did you just turn it on from the dash or turn it on and then attempt to engage it with the wiper stick?
Are you sure you need the fuse for the cruise control. My cruise control wasn't working, neither were my brake lights. All 7 bulbs were burnt out. When the brake lights were replaced the cruise control worked.
The stop light switch may cause the problem. If not adjusted properly it will not allow the cruise to engage. Check that there is no contact with the switch (Plunger) while the brake is not being depressed.
A clockspring controls the air bag, cruise control and the horn. I had mine replaced. On a Grand Caravan Dodge.
One thing that can make the cruise control stop working is if the contacts are shot or have become corroded. It is also possible that the fuse is blown or that the module needs to be replaced.
Cruise control is an accessory.
It is possible to convert a car without cruise control to have cruise control. Many auto parts stores sell kits which will install cruise control in a vehicle.
There are several ways to fix the cruise control on your Mercedes-Benz depending on the problem with the cruise control. Make sure the fuse for the cruise control is not blown.
2004 sebring convertable cruise control not working - what to do?
I was researching that very question. As I searched I replaced the clock spring, the buttons on the wheel, the switch on the bottom of the brake master cylinder. Then after all that I was made aware of a recall notice for the electrical link to the cruise control from the bottom of the brake cylinder. On mine there were 3 in-line fuses. I replaced that with a junk yard one and I got my cruise back. Hope that helps.
There is no isolated fuse for the cruise control. It all runs off the 20A gauges fuse. If you are having trouble with the cruise control I would check the Cruise Control Module or the Cruise control Servo. What symptom is occurring?
If the cruise control on your 1987 300ZX does not work, you might have an issue with the cruise control fuse or wiring. You could also have a problem with the switch that turns the cruise control on and off.
Your speed sensor probably broke and needs to be replaced. If the car can't determine it's speed, then it may automatically disable the cruise control.
