Question about 2005 Pontiac Grand Am

Horn is not working, check engine light is on

My horn is not working. I had problems with it "sticking" previously but now it's not working at all. I replaced the relay and/or fuse in the engine fuse/relay box but this did not solve the problem.

Also, my check engine light is on, last time it was due to "bad gas" so I've purchased some GUMOUT fuel system cleaner stuff which I will use soon. I have to get an inspection in August and I need both problems solved. Please help!

Your horn not working is probably due to the horn switch in the steeringwheel

Horn doesn't work


Check the fuses. Check the relay for the horn.Check the connections to the horns. There will be 2 horns disconnect both. Use a test light ground it to the battery and stick the probe in the wire connector for any of the horns. Have someone press the horn button. If your getting power the test light should light when the horn button is pressed. If it does? You have wither bad grounded horns or bad horns period.
If the test light doesn't light? You have a problem in the steering column remove the steering wheel and you will see in there a plastic ring with a copper or brass button that drags on another ring to power the horn button. these pieces ware out and the spring loses its tension. This is a common problem with Ford Trucks.
Good luck
Please give me good feed back of somekind for me on here.
Thanks

How to fix the horn. or rewire a horn. the previous owner stated that he took out the fuse for the horn because it would not stop beeping . I need the horn to work to pass safety


Hi,
Apparently the previous circuit of horn is shorted making work all time.
Just check entire wires, relay and horn button in your car for shorted and have them fixed.
Otherwise you need to install new set of horn system ( horn button, wires and relay)

Purchased 1996 Ford Crown Victoria. On driving it home the cruise control went out. Tried to reset and won't work, as well as the horn. What is the problem?


The horn relay is located toward the front of the engine. It is located just behind the radiator overflow reservoir and attached to the inner fender next to two other relays. It is the only one without a plastic cover over the top of it. FYI, our Crown Vic horn didn't blow, and the cruise didn't work. I changed the relay and still no horn. I decided to check the horns themselves. Found wires disconnected from terminals. Touched wire to horn terminal and horn blew incessantly. (previous owner had disconnected horn rather than diagnose why) Pulled the horn "button" from steering wheel and disconnected the wire leads and horn quit. Disassembled the "button" assembly. Foam had degraded over time between the contacts. (Ford has discontinued this part). Cleaned and replaced foam with Scotch foam mounting squares with holes punched out over contacts (2 layers thick). Re-assembled and viola! Horn and cruise control both work! Relay was bad as was horn button.

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.

The horn has died on our 2000 passat estate it got quieter and quieter and harder to work, a friend recomended banging it with a hammer while pressing the horn. This did not work although the horns made a...


Check the horn relay is ok,
Check the horn ground is ok.

Place a trouble light across the horn supply- when horn is pressed it should light up steady.
If it lights up, the voltage to the horn is ok -then a replacement horn should fix it.

1988 Ford Crown Vic Horn Relay Location


The horn relay IS NOT located in a box toward the front of the engine. It is located just behind the radiator overflow reservoir and attached to the inner fender next to two other relays.

1988 Ford Crown Vic Lost Cruise Control


Although I don't think the cruise is an issue for safety, reach in under hood , or in grille area and find your horn(s) and just pull the connector off them temporarily, so they won't blow & put fuse back in and see if cruise starts to work again. It's not unusual for circuits to be labeled wrong or not at all in fuse panels. Then you can turn your attention to horn problem.
