When Refinancing Do You Get Your Down Payment Back?

refinancing

i wanted to know if when you refinance if you get your down payment you place on your car back. or when you pay off your car do you get it back, because when i financed my car it was 11000, with taxes the car was 13000, i but 5000 down so i thought the price left would be 8000, but when i started making payments it was starting from 13000, so i wanna know what the 5000 was really for, i have read in other seats where people payoff there car and they get there down payment back.
