Hi someguy , my system only responds if I push the defrost first and then select from there . I get functions from all selections but even to shut it off I have to push defrost and then off . I thought a vacuum leak would make the system default to defrost only . I have a manual on CD if that helps .
Yes the console has to come out to remove the push-button assembly , but it's not too hard , I did have to remove my armrest and push the seats back and recline them though , then you have enough room to slide the console back and out . I was hoping that resoldering my amplifier would cure the pushbutton problem but it didn't . Good luck .
