Subject: How to check an inoperative horn
Customer's exact description: ...the horn on my 1995 Buick LeSabre does not work...how to fix?
Here's how it's done:
Step 1. Start with the pre-check:
Do a Thorough Visual Inspection
Do a thorough visual and "hands-on" underhood inspection before starting any diagnostic procedure! You can find the cause of many problems by just looking, thereby saving yourself a lot of time.
• Has the vehicle been serviced
recently? Sometimes things get
reconnected in the wrong place, or
not at all.
• Don't take shortcuts. Inspect connectors
and wiring which may be difficult to
see due to location.
Step 2. Instructions:
One. Remove the horn relay and check for battery voltage at the relay connector terminals.
Two. With the horn switch depressed, measure voltage from the relay terminals. Wear hearing protectors, if someone is assisting you and depressing the horn switch while you're under the hood.
Three: Connect a fused jumper from relay connector terminal 30 to terminal 86.
Four: Disconnect the the suspect horn connector. Connect a fused jumper from the suspect horn terminal B (dark green) to the positive + battery terminal.
All the best,
Ben
