    If you don't mind it, it'll be a 2 hour job most likely. Disconnect battery, unplug harnesses and you'll have to remove the seat out of the car.

    If i'm not mistaken, the part numbers are:
    89024402 and 89024405

    Although I believe you may just need 89024405. Rippy can double check that with you. They are considered hazmat because they are like tiny explosives. I've never personally had to do the job, but I have a 33mb manual if you'd like to skim thru it pertaining to just the seats. You'd have to drop me a PM and a spot to upload this thing. LOL

    I wonder if that's why my airbag light is on? My drivers seatbelt feels "worn out" lol. What exactly is the function of the pre-tensioner?

    It activates in case of an accident by retracting the seatbelt a few inches to keep you in place and away from the steering wheel. Fascinating geekiness.

    Old thread. But the airbag light that your talking about can also be triggered by the wiring harness located under the passenger and driver seat. Wiggle the plugs and force them back together snug. And play with the wies in the backs of each harness to make sure they are inside each clip securely. That fixed the airbag light on my 03 cts. Quick and easy. Hope that helps.
