Be trying to purchase a new or good second had black steering wheel with controls for 1999 Ford Explorer. Have found a couple but are are in as bad condition as the one I have, I'm in Western Australia, Australia...

I have changed the battery and the starter because my car sometimes starts and then wont start. I've wiggled the ignition and the tilt steering wheel to check if it was the ignition and it started. Then i turned car off and next day would not start again. I haven't gotten the car to start again since. Maybe relay?
