Park yer car in the fridge and test them then!!!!! I did swap mine in the summer as well and couldn't wait for winter to try them out!!! They DO switch on manually though at ANY temperature when you switch the rear demister on... eg when you're driving in the rain and just want to clear the mirrors...
