Just bought a uses 07 Caliber SXT and forgot to check if the Horn worked. Well it does not work from steering wheel, but works fine for the Alarm system. Does not appear to be the physical horn, but uncertain. Also fuse in slot 23 is fine.
Need Help! Thx.

Hello,

The horn relay is located in the TIPM under the hood behind the front bumper on the driver side the tipm is where the fuses are. Here are some guides and fuse panel diagrams so you can do some quick tests if everything tests ok check the horn itself they go bad all the time.

Please let us know what you find.

Cheers, Ken

My car horn does not work and I can't find any information in the owners manual regarding the horn. I am not sure which fuse is for my horn and can't find it under the hood either. Could it be the fuse needs to be replaced?

This could be a horn issue but the way to check the entire system is to go to the horn and check for 12 volts on the single wire when the horn is being pressed.

https://www.2carpros.com/articles/how-to-check-wiring

If there is no voltage there, then you have a wiring issue or the TIPM has failed.

Both the horn and TIPM are common failures on this. However, to confirm this we need to monitor the cluster data with a scan tool and find out if it is picking up the button being pressed.

If this is then the button and the clock spring is okay.

Please see the wiring diagram for more information on this testing.

Let us know what questions you have. Thanks

I would use a test light at the horn itself to see if the horn has failed. This guide can help, have a helper hit the horn for you. Use the wiring diagrams above to see what color wire it is, there is only one going to the horn.

Please go over this guide and get back to us.
