Question
Just replaced speedometer (instrument cluster) on a 1993 Geo Prism.
Airbag light is now on steady. Car has never been in an accident. How can I reset this airbag light?

Answer
Hi Steve:

Your vehicle will require a scan tool for the proper diagnosis (and not the one at Auto Zone---it needs to be  airbag system specific, like a good body shop or the dealer).  It may be the speedo head is the problem itself however the fault may just lie in being powered up without a complete circuit requiring a simple 'reset'.
I hope this helps. there isn't much you can do without starting wit a scan to see what the fault code is and then going form there

Good luck
Doug
