I have a 99 Ltd with the dreaded electronic heater controls which also includes the air recirc button. The problem Im having is when the temp is set to Cold the button will not switch to fresh air or stay there if I do manage to get it to switch. If I increase the temp to warmer it automatically switches to fresh, when I decrease to cooler it switches back. I can hear the flap in the heater box so thats not the issue, I just want it to stay on fresh.
