Airbag warning light won't go off even if you put the seatbelt on and stays on all the time on passenger side. Looking for someone who knows how to fix this on the cheap
Airbag light on instrument panel stayed on constantly. Read forums on the internet and found that the bulb in the dash for the passenger airbag light had blown, replaced bulb, airbag light on instrument panel went out. $6 fix!!!
Air bag ,warning light will turn on for periods of a few days then go off.
This is the second time my car has had this problem in the last two years. When it airbag warning light illuminated stayed on, i took it to the madza dealer and they told me it was warranted and repaired it at no charge. They found that the spring had slipped off sensor. Now again the light has came on and i do not understand how a safety feature came just malfunction so easily without any damage to it and i fear that the bag may open on me. I no longer had any warranty on my car and feel that with a safety issue like this it should not malfunction without a cause and should have to be covered at no charge even after the car warranty has expired.
Airbag light comes on when starting, as usual, then goes off and comes back on right away. Stays lit.
Airbag light on dashboard
passenger air bag stays off even with someone in the seat
Airbag light flashing
The light illuminated around the time the driver's side seat belt mechanism failed. When the car is turned initially wont come on, after a couple of minutes it turns on.
Passenger airbag light comes on for approx. 5 seconds then goes out like normal as if someone was sitting in the seat, then the airbag light in the dash cluster comes on and stays on. No flashing just steady light. Not fixed yet. Looking for ideas
The airbag light came on 4 years ago . I took it to dealer , they charged 300 for diagnostics and then about 400 for repair. It was ok for 6 months and after the warranty of their repair was over the light came back on :-( .i hadto spend about 300 $ again to repair it. Now it's back on, and I haven't bothered to repair it
Same problem. Also the passenger airbag light behind the gear shift comes on randomly. Even when there is no weight on the passenger seat.
Airbag light will not go off.
for a while horn didn't work - now passenger airbag light is on all the time
Airbag light came on, unsure what is wrong
the dealership service dept noted that the airbag is functional but the light itself is the problem. we decided to just let it stay that way.
