My name is ***** ***** I am a professional here at Just Answer. I noticed that your question was not getting a response and thought I would see if you still need help with this.I apologize for the delay and I hope I can still assist you with this here.
This type of fault here can be caused by shorted or damaged wiring in the steering column or the electrical contact coil behind the steering wheel is shorted or failing.This needs to be inspected further to locate which is the cause here and once located repaired or replaced from there.
Thanks Pete
