Hmm i have no idea how to do it, but seriously if i were you i
will leave the airbag as it is.
Why?
1. Insurance
If one day u kanna accident (touch wood), and got seriously
injured, i wonder whether your insurance company will compensate
you since you deactivated the airbag. They can say it's your own
action that caused you to be injured to this extent. Sure..you can
sue them etc., but it will take a long time and provided you are
still alive to do so.
2. Safety
Yeah airbags are expensive. But they are there for a purpose. Your
seatbelt may save u from hitting the airbag, but one day you may be
involved in such a serious accident that the whole steering column
is pushed towards you. True, in the event of a serious accident,
you may not be alive with or without airbag. But surely you will
wanna take your chance.
3. Odds of meeting with an accident again
Well I dunno about you, but I guess you don't meet with an accident
every month right? If so why not leave the airbag alone? If you
wanna take it out, you still need to find a workshop to do it for
you. Most prob it won't be free.
At the end of the day, i will rather pay $3500 to replace the
airbag and walk out of a crash alive rather than deactiating the
arbag (it costs money, time, effort plus you may not live to regret
it). Besides, what is your car insurance for?? Dun think you will
be the one footing the bill. Besides that, in an accident,the air
bag is normally not the most ex item to replace anyway..
just my 2 cents
