When I turn the car off the heat blows high and will not cut off. Have to disconnect battery or will run it down. Have also noticed instrument panel lights flashing after car is turned off. Recently noticed that it happens after rain. Took to dealership twice - unable to detect problem after keeping vehicle for 2 days.
