Air conditioning turning on with defrost is probably normal, a/c may be used to dehumidify air, but the other problems sound like a bad ground somewhere ans the system feed back through another circuit looking for a path to ground.
Have any light bulbs been replaced recently, ( particularly the left rear brake, turn or tail light)? If so I suspect one of the bulbs is wrong.
I know this is late but ... there's a service bulletin for a bad ground in the front fender, causing a wide array of strange electrical issues.
