help. none of the controls are working, the previous owner said the wiring is off and it will work with rewiring it back. but instead of just rewiring it back i was thinking about just buying one and replacing with the stock. the buttons dont really come back to place. i think the buttons are loose on the radio and ac controls. where can i get cheap replacement of the radio and ac ?
