I have an 05 Mazda 6, today my horn would not work and my cruise control does not want to turn on everything else is operational. Does anyone have an idea of what it could be. Both went out the same day. I appreciate the help.

 

a fuse maybe? thats the first thing that came to my mind, but i have no idea. hope you find out whats wrong.

 

Hi, Do you remember how this was cured as I have just had the same problem .

 

Hi, if your cruise control switches are located on your steering wheel, then there is a good chance that your horn\cruise control terminal connector behind your steering wheel has a poor contact or even come apart.
Hope this helps!

 

Turned out to be the bcm module had burnt itself out in the fuse box in the car.
