My airbag cover has broken due to the time of usage and me horning in the bad spot of it. Airbag is intact, I have not crashed or anything.

 

I just purchased the cover only and I want to know if there is any video or instructions out there on how to replace it?

As far as I know you can't.

 

Certainly not unless you are trained and qualified to do so.

A whole second-hand airbag unit is not difficult to fit.
