the easy part is the heater. Likely the blend door actuator motor. A pretty easy change and well discussed here. Do a search. As for the windows, I'd check fuses then I'd check the wire harness where it goes thru the door jamb into the door. I've had 2 motors stop resulting from a frayed wire. If the motor is completely stopped, no noise or anything I'd be looking at the silly little things first.
