HORN SYSTEMDESCRIPTION
WARNING: ON VEHICLES EQUIPPED WITH AIRBAG, REFER TO ELECTRICAL, RESTRAINTS FOR SAFETY PRECAUTIONS. DISCONNECT THE NEGATIVE CABLE FROM THE BATTERY BEFORE SERVICING COMPONENTS INVOLVING THE AIRBAG SYSTEM. ACCIDENTAL DEPLOYMENT OF AIRBAG AND PERSONAL INJURY CAN RESULT.
The horn circuit consists of a horn switch, clock spring, wiring, horn relay, and horns. The horn switch is a membrane switch located in the airbag trim cover. The horn is located below the right side headlamp.
OPERATION
The horn circuit feed is from the fuse to the horn relay in the Junction Block. When the horn contact is depressed, it completes the ground circuit. Then the horn relay coil closes a set of contacts which allows current to flow to the horn. The horn is grounded at the shock tower through the headlamp and dash harness.
