Brake push back...?

After recently tearing a part my dash, when the windshield wipers are on I get a tad of push back when applying the brake. So if I am at a red light, foot on brake, every time the wipers pass by I get reverse pressure (feel) from the brake.... Just strange.

I'm aslo getting a high pitch wine from my center console every once in a while - it seems to be coming from the temperature controls. Every time I hear it I pull over, take the center console off and it stops.............. wtf? Im stumped lol...
