electrical problem on 2002 Suzuki XL-7

2002 suzuki xl-7 not a 2007
My error
airconditioner turns on with defrost, radio dial blinks with left turn signal, buzzer sounds when brake applied with engine off and key in ignition

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.
