Its not advisable to do it without proper knowledge.If done without care, it can explode and be very dangerous.Always get it done by professional.I personally advise.

Still the procedure is as follows:---

On The Rear Of The Airbag Housing There Are Two Small Holes, One On Either Side. Take A Small Flat Blade Screwdriver And Poke Around In The Hole Till You Release The Spring On Either Side That Holds The Bag In Place. The Bag Will Pop Out A Bit. Once Both Sides Are Released The Bag Is Free. Unplug The Two Airbag Connectors By Pulling Up On The Center Clip Lock, And Then Squeeze The Two Tabs On The Sides Of The Connectors Together And Pull Out. The Airbag Connectors May Be Melted To The Air Bag. You Will Then Have To Replace The Clock Spring
