you need to clear all the codes.the histroy codes will go and the current will stay.hold the off and warmer buttons on the a/c panel.when you see it go into diag. mode.use the hi fan button for yes and the lo fan button for no.it will go through the codes then stop on pcm? or bcm? push the lo button for no until you see clear bcm codes then push hi for yes.it will say bcm codes are clear.continue through all the computers.when you recheck the codes those that are the current codes and will need to be repaired
