Where is the horn relay under the engine

The horn is in front of the grill and radiator on the drivers side it is a black disk.
The relay is int the engine compartment on the drivers side in relay/fuse-box. The name "Horn" should be on the fuse-box lid to identify what relay is needed.
Question: Is your horn only sounding at certain steering wheel positions? If so the problem the brass contact plunger in back of the steering wheel is worn out. You can buy a kit with the ring and plunger to fix that.

Where is the horn(s) located on a 1999 buick lesabre custom?

It doesn't matter where you "hit" the steering wheel, both horns are wired to sound at the same time. You could have a defective horn relay, but more likely you have defective horn(s). Oh, and you'll find the horns under the hood somewhere adjacent to the engine

1989 buick lesabre horn won't blow .check relay's on passenger and driver side under hood .push horn button hear quicking in fuse box under dash on passenger

possible horn itself is faulty and needs replacing. you will need to locate where the horn is and apply power to the horn from the battery. if the horn sounds then you know that it is a broken wire th=o the horn

I have a 91 buick reatta whos horn does not work,have replaced the fuse,no sound.

First, I should say that this is probably not the normal reason a horn does not operate...but, if it helps one person remedy the "non-functional horn" it will be worth the time it takes to write about it. Even though I am not a mechanic with lots of "mechanical terms", I hope I will be able to write up this "FIX" in a way that is understandable.....So here goes:
Neither horn button on my 1990 Reatta would work...power was traced to the steering wheel, but for some unknown reason there was no power getting to the button assembly. VERY IMPORTANT: We disconnected the battery and removed the Airbag Fuse and ONLY THEN did we pull the center ABS airbag module from the steering wheel..still connected to the steering wheel though.....
(Please read directions regarding Removal of the Airbag Package/Module found on the Reatta Club website, before doing the directions also include a step that says to disconnect the "YELLOW" WIRE that connects to the airbag and is found under the dash...but we could not find the yellow wire and continued cautiously without disconnecting it...but I am not saying this is the proper or safe thing to do!!!!) .....then the button assemblies were easily changed (following Reatta website instructions) and still no sound. Again, the battery and fuse were disconnected and the ABS module was removed and THIS TIME, with a flashlight, we looked into the the steering wheel, where the horn harness spring wire goes... and saw that the white plastic encasement, in the lower section of the hole, had been broken and a small peice of the plastic lay across the metal in the bottom of the hole. This peice of plastic was keeping the end of the harness spring from making contact with the metal at the bottom of the hole. I wrapped tape, sticky side out, around a thin "eyeglass" screwdriver, inserted it into the hole and retrieved it out of the hole..(vaccumn clearner would probably work as well)....thus leaving the metal inside, free of obstruction. Steering ABS airbag module was then replaced in steering wheel, along with the horn harness section lowered into the hole. Battery and fuse were again connected and the car was cranked....VOILA! ...the horn buttons sounded LOUD and clear! It was a beautiful sound!!! :) As said above, this is an unusual situation, but might be something to check before replacing parts....hope it helps someone. Debbie

Horn not working on a 1991 ford escort

I replaced my horn the original horn just burns out. Get a new horn for the escort, they are much louder. You can just reach under the front passenger side of the car inside below the right headlight and slide your hand in to remove the nut that mounts the horn in. good luck
