I attached the entire wiring schematic below for you to review. At the window switch, there should be a white wire. Check that for power. It comes from the window relay. Also, note that power is from a circuit breaker.
Here is a link you may find helpful:
The actual wiring schematic is one page long. I had to cut it in half to make it readable for you. I did overlap the two so you can follow from one to the next.
Let me know if this helps or if you have other questions.
