Steering wheel controls dont work. - RL Acura Cars & Trucks

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.

there could be a broken wire in the steering wheel which would mean possibly having to remove the steering wheel but there will be an air bag that could go off which would be dangerous so its best left to the professionals unless you know exactly what you are doing as regards taking off steering wheels.

you wll have to remove the steering wheel to find the problem iam afraid ,its called a serpent coil or whatever and this is playing up ,make sure ignition is off nd remove the airbag to get to the steering controls but whatever you do remove the airbag but do not unplug it or the airbag light will stay on

TO REMOVE CRUISE CONTROL SWITCH. FIRST TURN OFF RADIO TO KEEP FROM LOSING CODE. DISARM AIRBAG IN THE STEERING WHEEL BY REMOVING NEGATIVE BATTERY CABLE WAIT 20 MINUTES FOR AIRBAG TO DISCHARGE BEFORE REMOVING AIRBAG AND HORN PAD IN STEERING WHEEL.ONCE AIRBAG IN STEERING WHEEL OUT.YOU CAN REMOVE THE CRUISE CONTROL SWITCH.BECAREFUL REMOVING AIRBAG IN STEERING WHEEL CARRY IT AWAY FROM BODY WITH AIRBAG HORN PAD POINTING UP.IF YOU DROP IT.DONT PUT IN BACK IN STEERING COULD DEPLOY ON INSTALLATION.

This is a dangerous problem, dont worry about the abs or trac lite till you get the steering fixed..... Could be a loose steering rack ...when you move the steering wheel that much and the tires dont move you have a serious problem..PLEASE DO NOT DRIVE until you can have someone look under the car it should be vey very easy to see whats wrong Good luck

Check the fuses and relays. Generally if only 1 accessory doesn't work, the problem is with that particular accessory. When ther are several that don't work, check fuses and relays.

I installed a body lift and now none of my steering wheel controls dont work any ideas

sounds like the steering wheel got turned during the proceedure to replace the shaft which means that you broke the clock spring which sits under the steering wheel.

clean the switch signal contact.
