Defroster comes on when turning key

Still Crusin

I recently had my a/c system completely overhauled. Climate control module included. I've noticed as I'm turning the key to start the car, the defroster will start blowing full blast when the key is at the position just before it starts the car(KOEOff). This symptom occurs even when the climate control function knob is in the OFF position. I can't really say its a bad problem, but I'm original owner of this car and I don't remember it doing this when it was new.
Almost seems when systems are going through their check process just before the car is started, its triggering the interior fan to come on. If I leave the key in that position, the defroster will continue to blow.
It doesn't do it every single start, but I'd say it does it most of the time.
Any thoughts?
