Word of Caution for Disconnected Rear Defrost - Taurus Car Club of America : Ford Taurus Forum

Hey, just a PSA for anyone who has a disconnected rear defrost tab:

My rear window completely shattered a few nights ago. I brought it to SafeLite and after having it repaired (for $270..)
they explained to me that the cuplrit was more than likely my rear defrost being disconnected, and that it arced with the glass.

It wasn't a fun experience... especially since this is my first month of car ownership.
Neither was driving I94 from the airport over to A2 with a gaping hole in the window.

Stay safe guys! Pictures attached.

Wow, I never even thought of that as a problem like that.

Thanks for the heads up!

It isnt arcing that caused the problem. High resistance is the defroster, most likely at the connector, caused excessive localized heating at that point. Thermal expansion at that point caused it to shatter.

Ah, gotcha.

I only understood about a quarter of that, but gotcha!
