I have a blue 91 olds regency eleite butthe cruise control buttons on the steering wheel are broken off,,where can i finf replacement buttons

Was Cruise Control working before the New Horn was installed? The power supply to the Horn, (input to ground wire) is connected to the Cruise Control Module (CCM). This CCM is wired to the Relay Switch Box located in the Engine Bay. The Relay Box cover will have a Chart indicating what function each Relay coresponds to. Your local autoparts store (AutoZone) can test the Relay Switch, and you'll know (if any Relay) need to be replaced.

The CCM is also wired to the Steering Wheel, but first passes through the Clock Spring Coil, located just behind the Steering Wheel. The Clock Spring allowes for the Function Buttons on the Steering Wheel to have power while Steering Wheel spins.

The Clock Spring can malfunction or break, its rare, but this will cut power to the Function Buttons on Steering Wheel. If ALL the buttons on Steering Wheel dont work, then the Clock Spring is the Culprit. The Coil may need to be replaced.

The Cruise Control Module itself may have failed and also would cause a few or all Steering Wheel Functions to quit working.

But first check the Relay Switch Box and examine the Harness Cables connecting (Steering Wheel--to--CCM--to--Relay Switch Box--to--Battery Supply).

Also if Cruise Control was working before the new Horn was installed and now not working, then most likely the Problem is a bad wire connection somewhere and/or is a faulty Relay.

Most likely a broken wire in steering wheel

Way under your dash beneath the steering wheel you can probably feel two small buttons on either side of the steering column. One is for your cruise control I believe, and the other controls your rear brake lights. You probably noticed some broken black pieces of plastic on your floorboard. That's the broken plug that kept the button pushed in to turn your lights off. Replace the plug and the lights will go off.

If the Air Bag light was on, it's a dead ringer for the "clocking" spring. If not, it could be the other circuit paths that go thru it, such as the horn and steering wheel controls. It will require the removal of the steering wheel, and installing a clocking spring can be real easy or extremely complicated.

Maybe you just have dirty contacts that you might clean carefully, or a loose or broken wire.

Applying the brakes drops the cruise control function. Check for bad brake pedal interlock switch.

1. Remove the lower steering column cover.
2. Remove the AIR BAG bolts from the back side of the steering wheel with a T-30 socket. Install the bolts back in the air bag for reassembly. The AIR BAG will snap into place when pushed down on carefully.
3. Remove 2 screws on the bottom of the steering wheel cover. The wires need to slide out so the switch can be removed.
4. Remove the cruise control switches.

The AIR BAG does not have to be disconnected to remove the switches, just don't let it flop around or stretch the wires.

I need to know what year and model first please.

if you disconnect the battery and let it sit awhile this will disable the airbag.

Replace the Clock spring. It is mounted behind steering wheel. It alows electrical connection while the wheel turns.

So after you push the button and then press the set button in the steering wheel it does not get into cruise control ? It sounds like a minor electrical problem. If you have warranty still I think the dealership should fix it for free.

Sorry i have not been able to help you.
