Horn Relay Location
1991 Cutlass Supreme SL Coupe
Troubleshooting Horn but no manuals and cannot locate the Relay or Fuse if there is one,
The Fusebox-Cover diagram cannot be read.
All help appreciated
Thank you in advance, Jack

If I remember correctly, there are some relays to the left of the radiator (left if you’re standing in front of the car) and then a bunch more on the firewall near the blower motor. Look for green, orange and black wires going to the relay. Black should be the ground trigger from the horn button, orange is power, green is the horns.
