HELP! My power windows are stuck down and its starting to rain!

I drove my 1984 300D through the carwash yesterday. The window lowered and raised normally before I went through, and lowered after I went through, but when I tried to raise them, the driver's window and the right passenger window will not go back up. I checked the connections on the switches in the shifter console and they seem ok. I have a Haynes Manual wiring diagram that shows two "window lift relays", but gives no instructions as to where they might be located. Can anyone help? It's beginning to rain. I don't know if it's raining because I just washed my car, or because my windows are stuck down.
