Heated wipers for trucks

I have seen them, and they do get quite warm. Even saw a pair burst into flames. That was not a desirable result!

 

I wonder if they can crack a windshield like the defroster on cold winter morning?

 

A windshield cracks from an existing crack already present, then with the thermal differential of cold versus hot, the crack propagates. Windshields do not crack simply by applying the defroster to a cold, crack free windshield.

The same science would apply to a heated wiper. No, it would not crack a windshield in a cold morning, so long as the windshield was already crack free.

 

I'll explain that to my windshield

 

You can get a washer fluid heater for less money, should work pretty good, some high end cars have them.

 

Google heated wiper blades.
everblades.com and others

 

Just ordered a set of the Thermalblades for my Pete. After I get them installed and have the joy of running through another Colorado snow storm, I'll give an update. Reaching out and banging the wipers used to work fine before I had this 387 where I'd have to have spider monkey arms to reach the dang windshield.

 

I installed aftermarket heated blades on my new 4070A in 1973.

 

He!! I'd settle for self cancelling turn signals
