This sounds like a risky experiment, the windshield is likely to shatter with such thermal differences and the associated tensions.
If I am not mistaken, a windshield is created already with internal pressure to ensure it will shatter to pieces when the local pressure changes abruptly (via punching e windshield with a hard pointy object for instance)
