Hey does anyone have the relay location for the horn? I bought my '01 GT about 2 months ago & never checked the damn horn or cruise control. When I went to use them both about a week ago....nothing. I checked the fuses & the fuse was actually missing for the horn. When I replaced the fuse, the horn just went off continuously. I am hoping that the relay is bad & will fix the problem so that I don't have to pull apart the column. Did I mention that it is up for inspection? Just my luck. I am hoping that the fuse block diagram will point me towards the problem for the CC not working.

According to this drawing (4.6 2V), it's near the master cylinder. Connector c105

I was looking at mine and it appears to be in the fender well. As I was looking I thought of something.

If you disconnect the horns (so they don't make noise) and put your ear near the area of the horn relay while a friend pops that fuse in and out, you should hear the relay click. If it clicks, I would think it's a horn switch problem. If it doesn't click, I would think it's a relay problem.

Sorry man. The more I look at the manual the more I'm thinking that C105 is just a connector and the horn relay is in the relay block under the dash. Same troubleshooting as above but you can do it all yourself because you'll be under there anyway.

Sorry for misreading that schematic.

Relay block looks to be directly under the speedo. Here's a harness view. Look to the lower right quarter of the picture for "Relay Block". It should get you close.

thanks...yeah the c105 was just the harness connection at the firewall. i will check under the dash though where you specified. hopefully someone can chime in on which relay belongs to the horn. then i gotta figure out whats up with the cruise control. i doubt that has a relay. i don't remember checking to see if there was a fuse specifically for the cruise. right now i just gotta get this horn fixed. its funny, i feel like an ass when i go to lay on the horn at someone & hear silence.

im trying to find the horn relay too and will look under the dash, but my cruise works fine. i think i have skimmed over some other forum posts that sound similar to this problem and lead to some sort of ring connector inside the steering wheel. maybe not though, anyone feel free to still chime in on a more exact location/which one the horn relay is.

Just be prepared that ultimately your problem could lie in the internal wiring and clockspring in the steering wheel. There could be a short in there too.
