Hello all and thank you for participating in this thread. I have a 2004 Hyundai Elantra. The airbag light being stuck on is failing me at inspection. I went to the dealer they ran the diagnostic, said it was the sensor in the front passenger seat. They said I needed a whole new seat for about $2,000.00 so I went to a local parts yard, they had two Elantras with seats that would work one was 04 the other 06, I tried them both after disconnecting the battery and resetting the codes which as I understand it to reset the codes you unhook the battery then remove the appropriate fuses wait then reattach. I also drove the car for about 50 miles I read somewhere you had to do that to fully reset the codes. And still the airbag light is on neither seat works. Please if you have any idea or advice your assistance is greatly appreciated! Thanks you.
