My horn started blowing solid in the middle of the night. I had to pull the fuse. After looking at drawings it's either the horn relay or the FCM which drive the relay. What a pain to replace it. Can't thay make anything easy to fix. If it's the FCM I may just wire around it adding my own relay. Thanks for any help. I guess I shouldn't complain, my first problem in almost 4 years.
I concerned about the cost of the FCM since it has a microprocessor on it.

Its not the FCM...Its the Horn Pad in the steering wheel assembly.

 

Cool thanks. I look it up. Do you have to pull the wheel to replace the pad?

If I remember right its usually part of the airbag assembly. Mine went bad and I never got it fixed since I wont take my truck to the dealer...

 

Hopefully it is the contact pad. I did have that as a problem with an old Toyota truck I had years ago. At -40c it would start blowing and I had to pull the fuse, not fun at 4am and -40.
If it is the module it is costly. I had mine replaced under warranty and the dealer told me it was a $400 CDN part. It will be less for you, but it is not cheep.
