I accessed an OBD site recently and was reading instructions on accessing the codes. The site said up to '99 was accessed using temp control knobs or something and 2000 up by pressing the info and on/off button. Ok, here's where I get confused...I have a 1999 Seville STS and my codes are accessed by the info and on/off button method. Can someone enlighten me?
