Front seating area, passenger side, under dash, above kick panel, mounted in relay block.
You will have to drop the dash down from the glove box over to the ashtray. (It's not hard.) Then right above the fuse block follow the red wires to the relay block. Reach above and toward the back of the car and then feel downwards. The relays are installed so they are not visible. The owner's manual says you can "push the block up and off" and drop the whole block down for easier access. My relay was original and yellow. Replaced the wrong one first but when the emergency flashers quit working it was easy to figure out. I hope this saves someone the hours of frustration I went through thinking the relays were pushed in front to back or upwards and I could see them.
