Location of Chrysler horn relay

Answer 1

According to various publications, you can find it under the hood in a fuse box, or under the dashboard on the driver's side in a fuse box. However on the 1991 New Yorker I have been suffering with for years it is cleverly placed to the right of the instrument panel, top center inside of the dashboard. You must remove the glovebox, and then the glovebox mount which includes lower dashboard and ashtray. When this is removed you will see two sets of relays. Change the turn signal relay while you are at it to prevent another disassembly. I didn't see a reference to the specific model of Chrysler, but speaking from my own experience, I own a 1993 Chrysler LeBaron, and the horn relay is located on the relay panel beside the fuse box on the driver's side, but it is hidden from view so you won't be able to access it by removing the fusebox cover. You would have to remove the lower panel under the dashboard. The horn relay is the square shaped relay on the relay panel (the hazard flasher and time delay relay on that panel are round.) If you are troubleshooting a problem of the horn not working, the problem might not be the relay. In my case, the horn would not work, although the relay tested OK. So I started troubleshooting using the wiring diagram and discovered that the metal of the steering column was not grounded to to the chassis, therefore the horn button on the steering wheel could not ground to chassis ground and could not work. The way to check for proper ground is to look on the back side of the steering wheel behind the horn button. Remove the little protective cap you will find there to expose the screw that holds the horn button. Using an ohmmeter, touch one probe to that screw and touch the other probe to any bare metal under the dash to check for ground continuity. If there is no continuity, then the steering column is not grounded to the chassis and the culprit can be found by looking under the dash just to the left of where the steering column connects to the underside of the dash. There is a nut and a star washer holding a thin metal plate that is supposed to provide the ground contact for the steering column. My solution was to use a file to remove any corrosion or paint from the side of the star washer that contacts the metal grounding plate, as well as the nut that holds it in place. I also bent the grounding plate just enough to ensure that it would make contact with the metal under the dash when installed. Once I reinstalled the grounding plate, star washer and nut, I tested again for continuity with positive results and then pressed the horn button and it worked.
