In a 2000 Hyundai Elantra, the rear defroster relay switch is typically located in the engine compartment fuse box. You can find the fuse box near the driver's side of the engine compartment, usually near the battery. To confirm the exact position of the rear defroster relay, refer to the fuse box diagram printed on the cover or in the owner's manual.
