Also make sure you haven't disabled it via the drivers lockout switch. Embarassed but we've all done it.

I don't have a FSM that covers 1993 so these wire colors may not be completely accurate, but according to my 1991 manual to test from the driver side switch connector you'll need to jump pins 1 (wire is black with a blue stripe) and 5 (blue wire) to get the window to go down. At the passenger switch you'll need to jump pins 4 (green with black stripe) and 6 (blue with black stripe) to make the window go down.
