I have a 1998 Chevy Prizm. Last week the electric windows & door locks quit working. One window is stuck in down position & it's rainy season! Could this be the relay switch? Where is this switch?

check the wiring that is in the black rubber tube between the door and body sometimes the wires will break in there if they are ok, remove the driverside control and test for voltage on the hot wire then use a piece of wir to jump to other wires to see if they work if so the replace the driver side switch assembly
