Got a 2014 hyundai sonata and after i start the cat i hear a tapping noise coming from the. Center of the dash..if you put your hand there you can feel it. Took off the glove box to see i could see it but couldn't. Also took off below the piece below the steering wheel but couldnt see it..looks like im going to have to take off the dash next. But im hoping maybe somebody has had this problem to give me an idea of what im looking for.
