Visibility Related Problems of the 2013 Ford Mustang

Wiper problem

I bought this car through carvana. They mentioned it had no issues, after 6 months of driving I noticed the car is literally flooded inside and the electrical does not work well at all. I spent alot of money trying to fix the electrical including the wipers and ac yet both keep getting destroyed. Sometimes my traction system will go off and on and it's just so annoying how the water damage is eating away at a car I'm stuck overpaying for. It is a nightmare.
