My airbag light won't go off, what could be the problem?

Usually if you pull the fuse the light will come on because the system is disabled. You may need to get the airbag module checked out.
Its fairly touchy stuff, you have to be careful not to blow the airbag by mistake when you are working on the system.

Yes, the airbag/restraint light is often triggered by a disconnected seat belt safety plug located under the driver's seat. Some people disconnect this plug so the vehicle will not chime the alarm while the seat belt is disconnected.

what is the make and model

You need a repair shop or dealer, that has a data
base & the procedure to follow to reset things, after
the air bag went off

1st when the airbag light is on the system is disabled, so if u have an accident they will not work, as to the common cause read below.
When the airbag light is on it means a fault has occurred in the system and the airbag diagnostic monitor has disabled the system, the most common problem that turns the light on is a break in the connection to the steering wheel mounted airbag, this is due to a rotating ribbon contact that breaks under the steering wheel that connects the airbag to the wiring harness and the diagnostic monitor, the part is called th clock spring contact, a coiled up ribbon electrical contact that turns with the wheel

Usually the light is telling you there is a problem in the system and the system is disabled.
You may need to get the computer scanned for codes and go from there.

The light for the Airbag/SRS system is on because the system control module has sensed a fault and turned off the airbag SRS system. What you must do now is have a scan done of the airbag module to see what fault codes show up in the airbag modules memory.

Are you sure the smell was not deer meat on the radiator?
No one can honestly say its safe to drive and that an airbag won't suddenly deploy. Best thing to do is have it scanned to see why the light is on. Most shops will have a scanner that should work for this (save you the high cost of a dealer). The light may just be on because there is crash data stored in the SRS module and it may need be replaced.

Are you describing something like this? This symbol indicates that your vehicle has detected a problem with the airbag or seatbelt restraint system. It won't (or shouldn't) interfere with the way your vehicle operates, but it will likely disable the restraint system to prevent improper inflation of airbags. Obviously, the system won't operate properly in an accident, so you should get this checked as soon as possible.

Here's asite that will explain everything you need to know about airbag systems, airbaglights and resetting the system. Itshows you the location of the components and the procedure for diagnosingand/or resetting airbag light. Not allvehicles need everything replaced. You cancheck to see if your car is listed here. http://www.airbagsolutions.com/ Airbagsolutions.comalso has the fault code charts to tell you what is wrong and how to fix it! Some vehiclemanufacturers let you access and reset systems without a scanner (like Toyota,Lexus, Nissan, Infinity, Honda, Acura, Ford, Lincoln, Mazda & Mercury) andsome require a scan tool. Althoughit's a pay site ($14.95/day), it's a lot cheaper than going to the dealer Here's the page in this site that tells you which cars needa scan tool and which ones can be done without I hope I've helped you http://www.airbagsolutions.com/scanlist.aspx http://www.airbagsolutions.com/light.aspx http://www.airbagsolutions.com/vehicles_list.aspx
