It is ideal to diagnose the problem before trying to simply replace the part. This part is a bit pricier starting at $80 for a refurbished or aftermarket unit and up to $200 for an original equipment manufacturer (OEM) part. The following are other potential causes you would need to rule out before replacing the steering wheel buttons.
Common causes of the steering wheel buttons not working:
- Liquid, moisture, or normal use wear caused it to fail
- The clock spring in the steering wheel has gone bad
- Blown fuses or bad wiring caused a loss of power to it
- The body control module that it sends signals to is malfunctioning
What you will need
- Locate the hole on the back of the steering wheel directly behind the left steering wheel switch. Insert a Phillips head screwdriver into this hole and loosen and remove the one screw holding the switch in place.
- Using your hand, gently pry the switch off of the steering wheel. The lip of the airbag will be covering the right side of the switch. Once the leftmost side of it is out, the switch can be angled and pulled out enough to expose the electrical connector that is attached to it.
- Press down on the tab on the green connector that is plugged into the switch and pull it out of it. Note: Checking for power at this electrical connector would be one of the first steps in diagnosing whether the switch is the problem or not.
- Reverse the procedure and replace the old switch with a new one. You are done!
