It would be easier to help you if you posted make model and year of your car without looking at your profile.

Your fan speed problem is more than likely caused by a bad blower motor resistor, located under the front passenger's feet forward of the blower motor. Just follow the wiring harness from the blower to your resistor.

As for your window not working that I would bet is a window motor problem. But if you want remove the door panel with a test light clipped to the motor connector rock the switch back and forth making sure you have power on both wires depending on the switch position. If you have power at the wires than its a motor problem.
