Driver side window and mirror

Well I got in the car today I try to push the buttons to get my window to come down and adjust my mirror on the side of the door I push the buttons and nothing happens. My window will not come down and the button to adjust my side mirror there is not working either, but the locks from the side work all the way around and I can control the other windows and mirror on the passenger side work fine. Can you tell me what might be going wrong here? I am on dialysis treatments and I do not have a lot of money. Is this going to cost a lot to fix and what could it be? It was working fine.
