The most common cause of an airbag light that I've found is that one of the underseat airbag connectors was pulled slightly apart when the seat was put too far back. This strains the connection and opens the connector momentarily, just enough to trip the light. Your airbags are still fully functional - the light is a warning that there was an open connector at one time.

You don't have to go to a dealer if you have a laptop computer. You need the diagnostic software that Audi uses (called VagCom). You can download it legally and free from, and you'll need a $20 OBDII interface cable for hooking the car up to the computer (available on eBay). With this, you can scan the car and see which airbag tripped the fault light.

If it's an underseat bag, look under the front of the seat - you'll see harness connections facing you. The yellow one is the airbag connector. Use small zip-ties and zip it tightly together (don't damage the wires!). Afterward, use VagCom to turn off the light, and you should be good to go.

Or you can go to a dealer and have them take three minutes to turn it off...and charge you an hour's labor. Your call:)

Has to go to dealer to be reset. There could be many reasons your light is on: damaged wiring, faulty component, or even had a flat battery and the capacitor that deploys the airbag has been run flat.
the light means the system has been de-activated and may not deploy in the event of an accident.

1999 hyundai elantra airbag light

Depending on type of SRST, the air bag module may have detected something that in case of accident, it may prevent the airbags to deploy.
Have the car scanned for error codes. If the the warning light is ON, there sure is an error code.
Remember that some manufacturers (according to local laws), program the ECM SRST system to issue a warning at certain mileage or time, just to remind you that it is time to replace the air bag assemblies at the steering wheel and dashboard...

(Ouch... this may be expensive!)

Windows not working

is this one window or all windows? big difference in response.
Assuming you have checked your fuses, try replacing your window switch first, if its not that, its the window regulator. In some instances the cable has snapped but if you hear no motor sounds or grinding it is more than likely the switch or the window regulator motor. Take a look on ebay if you can for a new one. I bought my regulator and had it installed for the price you would normally pay for just the regulator if you went to a parts store and purchased a regulator alone. its not a repair you want to do if you are not familiar with what is involved, especially if your vehicle has side air bags. in my case, they had to be disconnected for safety purposes and when it was installed I got the airbag warning light on my dash. I bought a $30 airbag code resetter for my car on ebay and saved a trip to the dealer. Fyi, you won't pass smog with this indicator on your dash. Hope this helps.

Error b1034 airbag warning light

This light came on in my car when the alternator went bad. If the airbag system is not getting enough voltage it will show a warning indicator light. Check your battery and alternator to make sure they are putting out enough juice.

I have a 2005 toyota Coroola LE. The passager airbags doesnot show off and airbag icon appears on display. We need to fix to sell.

sorry dealer only as for the airbag software even on american market versions are all encrypted ,this is too make work for the dealers and expect a new computer and all new airbags costing around 2500 euros as this vehicle is 10 yrs old and at this age any fault must have all the airbags renewed ,europeon directive from last year and no doubt they will apply the same law at the dealers saying its a factory directive ,What you do is to remove the dash and cut the printed circuit to the relevant bulb then either connect to teh oil light switch or use a diesel engine pre heater relay that incorperates a timer and then connect this to teh light so it goes off after 20 seconds or so ,but i havent told you of this constructive engineering repair(COWBOY TYPE BODGE)

No they can only check engine codes and by law they are not allowed to reset any ststems that have a malfunction. A airbag light will reset if the problem is corrected.
