Airbag light and seatbelt light are both on

[amageed]

I have a 2003 Envoy. When I first start the Envoy, the seatbelt light flashes even though I engage the seatbelt. It eventually goes out but it would do that even without a seatbelt connected. The airbag light constantly stays on as well. Any ideas?? It's been like this for awhile but I would really like to know how to fix it.

The air bag must be scanned for any codes with a special scanner, try looking under the ft seats for a possible disconnect for the belt harness.

Your vehicle will require a scan tool for the proper diagnosis, but here's a site that will explain everything you need to know about airbag lights and resetting the system.

This website gives you the procedure for diagnosing and resetting airbag lights. See if your car is listed here. Although it’s a pay site ($14.95/day), it’s a lot cheaper than going to the dealer

On most vehicles, the airbag light should come on for @6 seconds, and then go off if the system is working properly. If there is a fault or a problem in the system, the light will remain illuminated, or flash continuously. If the airbag light does not work properly, some vehicles have an audible tone that sounds indicating a problem with the airbag light system. When the light is on (or the tone is sounding), the airbag will NOT deploy, even in an accident.
The flashing light on your car is telling there is a problem. On some vehicles, the light is flashing a two digit code. Once you know the code, you can most likely repair it yourself. There are fairly easy procedures that most people are capable of repairing.
Airbagsolutions.com has the fault code charts to tell you what is wrong and how to fix it!

Some vehicle manufacturers accommodate systems without a scanner (like Toyota, Lexus, Nissan, Infinity, Honda, Acura, Ford, Lincoln, Mazda & Mercury) .
Most all other vehicles require a scan tool for the diagnosis.
