95 Grand Am SE V6 problems

I have a GA that leak's coolant(radiator recently repaced), has no heat, and the right turn signal stays on when the lights are on and is very sluggish when the turn signal is turned on. This happened right after someone hit me in the right front (have knew lights). My driver's side window gos down put not up and the driver's side automatic lock unlocks but doesn't lock. I keep this car because it has a new ignition, new starter, new radiator, recent oil change and tune-up, new brakes and tire. Can anyone help, please. I don't know anything about cars.
