If the compressor has 3 air connections on top then the two lower terminals with nuts are the + and - supply inputs to the compressor motor. The two top spade terminals power a solenoid valve which changes a triple sequence (illegal?) to a combined blended triple tone. I don't think polarity is an issue but to check this connect a 12V battery -ve to the mounting bracket on the compressor. Attach 2 wires to a headlamp bulb and connect one to battery +ve. Then touch the spare wire to each of the 4 terminals in turn. If the bulb lights that terminal is at compressor ground. You can determine the operation of the relay in the same way. Between 2 terminals the relay will operate. Note those and then test each to the relay bracket to see if one side of the coil is grounded. By powering the relay directly from the battery you can then use the bulb to determine which contacts are 'made' when the relay operates. You will need a relay to control power to the motor. The solenoid valve probably only takes a couple of amps. You could run both the motor and the solenoid valve from the same relay if you just wanted a blended composite tone.

I have a 1998 chrysler concorde. The airbag light on the dash stays on and my horn doesnt work. How do i fix this without costing me tons of money?


Could be a wiring problem or the clockspring in the steering column.
You would need to pull the steering wheel and test the circuits.

Rodeo wiring diagram


The wire to the horn button is a live wire and it is shorted out when you press the button. This activates the relay and blows the horn. relays normally work by power coming to a terminal through the coil and out the other terminal to earth . This connects the coil and so the contacts are pulled together to allow power from the battery though to what ever is the relay for .. So what you need is power to a coil terminal on the relay and the horn wire connected to the other terminal. This will complete the circuit when you press the horn and the relay will close and the horn will blow.. To get this it may be necessary to piggy back off the power wire ( battery terminal on relay ) to a coil terminal .

Cant get power from batt when turn the key


A possible problem, a bad electrical connection, I would remove and clean the battery earth connection to the chassis and the chassis to body. If you connect a volt meter to the battery earth terminal and an earth terminal on the body, then the engine and try to start, you should not get a reading, if you do then there is a bad connection. It is strange connecting the meter across two earths, but if there is a bad connection, power finds the easiest path, which is the meter and it will give a reading, max reading acceptable 0.5 volts

Hi,
My name is Ben and I'm your guru, i.e., mentor, an influential teacher or popular expert: a management guru. - origin from Sanskrit, 'weighty, grave', for today.
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.
  • If battery voltage is present at both terminals, go to Two.
  • If battery voltage is not present, check the ORN wiring and the relay fuse for circuit.
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.
  • If voltage is present, go to Three.
  • If battery voltage is not present, check the black wire for an open circuit; check the connectors for proper terminal contact; check the in-line connector for proper terminal contact; check the spring loaded contact, slip ring, and horn switch for an open circuit.
Three: Connect a fused jumper from relay connector terminal 30 to terminal 86.
  • If the horn does not sound, go to Four.
  • If the horns sound, replace the horn relay.

Four: Disconnect the the suspect horn connector. Connect a fused jumper from the suspect horn terminal B (dark green) to the positive + battery terminal.
  • If the horn sounds, check the wiring to the horn relay for an open circuit or short to the ground.
  • If horn doesn't sound, check the black wiring for an open circuit, if OK, then replace the horn.

All the best,
Ben

Your problem is most likely a defective clockspring assembly. This is also called "spiral cable assembly" it is located just under the steering wheel on the steering column and makes the connection between the main wiring harness and the circuits for the air bag and the horn. I cannot give you wire colors because your question did not mention year, make, model, engine size or whether the vehicle is equipped with cruise control or not. (cruise control makes a difference in the clockspring assembly used on your car.)

Anyway, the air bag and steering wheel has to be removed to fix it.

Hello, my horn stopped working we took all of the fuses out even the relay under the hood everything appears to be fine. can you help me solve this problem i need my horn thanks.


Hi, sounds as if maybe it's the horn itself thats given up, Try removing the terminals from the horn ( easier if the horn is taken off ) and connect direct to a battery, if it has 2 terminals one is feed and the other earth, if it only has 1 terminal use the body of the horn as earth ( - ) and the terminal as a feed ( + ) if no sound, it's the horn, if it works, then connect and test lamp or volt meter to the terminals removed fromt the horn, press horn button and see if you have a reading on the volt meter or he light operates if using a bulb holder. Cheers

you may have a problem with the clock spring ( this is the unit that connects the steering wheel to the air bag) if you remove the steering wheel and earth out the horn pin and it works there is a fair chance it is the clock spring.; go to the reckors and get a second hand clock spring but ask them the precautions to take as they are a delicate item and easy to break

My horn stopped working on my 2006 Toyota Scion SB


most new cars have what is called a clock spring be hind the steering wheel.this is a flat ribbon cable like what you would Se in a computer.what can happen when the ribbon is damaged is the horn can quit working.the cruse control .and the air bag light will come also.but most likely one of the problems will occur.but over time the other problems start happening also.so are you sure you are getting power to the relay .use a volt meter on the terminals under the relay and have someone to push the horn button.this will tell you if you are getting power from the horn button.
