1997 LSS climate control

My 97 LSS climate control will not shut off. The control panel is active with the car off and if forget to turn the system off the battery will be darined because the blower will slowly ramp up to high trying to maintain temp. Even if i turn it off the battery will be drained after 2-3 days of sitting in the drive. I have checked all of thr relays that i can find and have come up empty. I am hoping someone has seen this before.
