the Horns (there are two)are located behind the parking light lens areas. to access, crawl under the front and pull down the tar paper seal at each corner and look up. you may need to only remove the single power wire at the tab at each horn, sand paper the tab and reconnect. that's what I did to mine - horns were fine - contacts were just corroded.
I have a jeep Cherokee of that year and I believe that what you are refering to is a spherical thermometer and horn assembly.
i have a 1992 Cherokee limited on it its under the lower pannel to the right of the streeing wheel
There are a couples of reasons why a 1993 Jeep Cherokee's horn may not work. One reason is the horn relay fuse may need to be replaced.
on my 93 Cherokee the horn fuse is #11, a 25 amp fuse.
Right behind the grill
In the middle of the steering wheel
In 1992, the horns are located behind the front bumper. The low horn is on the driver's side and the high (pitch) horn is on the passenger side right beside the vacuum canister. dont know about '92, but my '93 is located (looking at the front of the Jeep) behind the left headlight, beside the radiator. You can get to it by removing grille.
Very carefully
hey i have a 1992 Cherokee the relay is on the right side of the steering wheel behind the lower panel there are three relays there its the middle one i think
the horn fuse is on the right hand passenger side of the dash.
behind right headlight......hope this will help.
If the fuses are good on a 1996 Jeep Cherokee and the horn still will not work, check the horn relay switch on the passenger side fender wall inside the engine compartment. Also check to make sure that the horn is hooked up properly.
