windshield (screen) replacement
 

So through all my water woes the dealership has maintained that I have a small leak through the windsheild. Turns out the windshield has been replaced prior to me owning the car. I am getting it replaced again because of a crack.

Now what I need to know is what to look for. Neither the right side electric defrost nor the auto dimmer in the rearview mirror have worked, I'll bet they were never connected properly when the windshield was replaced. Anyone had their windshield out and what do I look for?

Thanks in advance.
