Airbag light won't light on dash

run the fault codes
could be sensor disconnected
air bag has been activated but not replaced
bulb blown

for the dash lights i would check the fuse...the turn signals not flashing, u need a flasher, usually by the fuse box,most are silver in color.

Fortunately your 1991 Buick is pre-steering wheel airbag...you will need to remove the steering wheel to gain full access to the "smart stick" Not to difficult with the correct puller...on loan from most parts stores...Hope this helps.

CANT DISABLE AIRBAGS NEED TO HAVE AIRBAGS CODE SCAN AND FIX THE PROBLEM.AIRBAGS IS A SAFETY FEATURE WITH CAR LIKE SEAT BELTS.YOU CANT REMOVE EITHER IF YOU DO YOU WILL FAIL STATE INSPECTION.THEY WONT PASS STATE INSPECTION IF CAR MISSING SAFETY FEATURES OR AIRBAGS AND SEAT BELTS DONT WORK YOU WILL FAIL STATE INSPECTION.

These problems are all due to a defective rotating ribbon contact that breaks under the steering wheel thios part connects the airbag and horn and cruise to the wiring harness. This part is called the clock-spring contact, a coiled up ribbon electrical contact that turns with the steering wheel while maintaining a mechanical connection to the airbag mounted on the steering wheel, to replace this part you must disarm the airbag system and remove the steering wheel, this requires a special steering wheel puller tool and that you disarm the airbag system before you start the work, to do this disconnect the battery negative cable for 1/2 hour prior.

not that i know off ,if its not coming on then you have two choices --connect airbag light to the oil light switch and hope the vehicle inspection man doesnt know this dodge,fit a heater glow plug unit under and connect light via this to bring light on and then make it go out without starting engine because they are getting wise to the oil light trick at the vehicle inspection.Or take it to the dealers ----normal cost at dealers is about 2000euros .If i have one failed at vehicle inspection then i have to have a certificate from dealers that airbags have been changed .More often than not the glow plug relay one will pass providing that i have checked the vehicle first ,because if they see it first?? then it will not pass without the certificate

Ok I did a little more searching and researching. The reason you don't have a light is because it is a mechanical airbag. I remember this system. There is no electrical wiring or control module or dash lights. Take it back to the inspector and make him aware of it and it should pass.

most times the problem is the rotating contact under the steering wheel has a break in the wiring of the flat ribbon connector, the part is called a clock-spring airbag contact.

i dont know of any state that fails a vehicle for an airbag light but it would be wise to get the system checked out. it means there is a problem with the airbag system and itis possible it will not deploy during an accident or it may deploy without warning. the most likely cause would be a bad clockspring

Check out the fuse box, rather have a mechanic check out the fuse box and root out anything blown out or wires shorted.
