Re: 2002 gmc envoy xl air bag light is on
You will have to be very careful!!! There have been cases where the airbag lights come on because of an internal computer problem. If you go to your dealer, or maybe a local shop, they will have to hook it up to a computer to determine the problem. Not to get too excited, but some people have had the bag actually deploy, so I usually make that known to anyone I help with an airbag light. Hope all goes well, and please be safe.

With vehicle running is check engine light on ? GM had a problem with the stepper motors that control the gauges . How to repair GM Instrument Cluster Speedometer Gauge Stepper
Are you looking to discharge and remove air bag or just remove from steering column
To remove air bag from steering column Disconnect battery Behind steering wheel there are four bolts tha hold bag on They are tricky to see the bolt holes but their there tight spot Now for the trick of wiring hopefully new style came with a release wire clip older style fed wires down column with release clip located under dash Remove the key ignition box The wires should be bright orange or yellow from air bag going threw column If old style you will have to loosen turn signal indicators if wires run under mount Once you get to end of wire clip Use a sewing needle to push buds out of clip mark your the main side Now for ease part Tape a little 3 foot wire to the ends before pull completley threw this will help pull bud wires back down threw tutn indicator switch Never force wire threw gently Removing air bag hopefully made simple by quick release clip under horn press
Just behind right rear tire up in the wheel well. Air inlet is inside right rear quarter near the accessory inflator. Compressor runs 3 lines one for the accessory inflator and one for each air bag.
THere are also 2 sensors, one on each trailing arm that senses load and then raises and lowers accordingly.
