Please reread my post. I am NOT talking about the main blower! There is a very small blower that draws air through the grille near the rear view mirror and blows it across a temperature sensor. When it does not work, the CCU is not getting a correct temperature reading, so it blows cold air at weird times.

Believe me! It will be worth your while to cut a small square of paper and take the troubleshooting step I requested.
