are you sure its not coming from under the hood

a tapping noise usually denote at motor problem

but it could also be the a/c relay not working correctly

If it is coming from under the dash it could be the speedometer cable.

Is it from the left side or the right side of the dash? Does it increase intensity when you turn your fan up? It could be something stuck in the blower motor.
