Climate Control Possessed!

When I turn my Aurora off amd leave the vehicle, the climate control stays on and displays hieroglyphics and flickers between F and C. Of I leave it in "Auto" the fan will stay on. Eventually it drains the battery. Also, the volts icon stays on. The "Security" light is hit and miss. When driving, the "Traction Off" lights up and the switch doesn't work. Finally, the driver's heater switch stays on for about a second then cuts off. Any ideas?

same thing, climate control stays on when vehicle is off...did you ever figure it out? anybody else any help? i have a 97

My mechanic found a faulty wiring harness under the driver's seat. It looked like it had gotten wet and shorted the wires. Since we replaced it, everything has worked fine.
