Hi,

I feel for both you guys... But, for others, a little caution may be in order so you can avoid this happening to you. Even if the Temp rises, Plastic also dries out making it more Temperature sensitive with regard to it's Elasticity and more prone to cracking in general.

There are a number of things you can do to try and prevent this. Easiest is simply to idle the Car until it's warm and let the Engine Heat warm up the window. You can use a Hair Dryer for a couple minutes to heat it up, or just put a Heat or Flood Lamp over it for 10-20 minutes (not too close to the Paint!). Also, store the Car with the Top Up if possible. If folding a Cold Top, try taking a towel and wetting it, then heat it in a Microwave for a couple minutes, then lay it over the window (using Tongs, Gloves or something to keep from getting Scalded) and let the Heat soak into the Plastic.

All a pain, I know, but maybe less so than dealing with a cracked window. Hope this helps...

Happy Motoring!...Jim'99
