1. Horn relay....I'm not sure you have a relay for it. Check under in the underdash fuse box for the fuse. If I'm wrong, the relay would be in that underhood fuse/relay box.
2. Do you have a Check Engine light on? I don't like guesses, but it could be a bad valve or some other bad ignition component. The timing chain could be stretching and tossing the timing out of whack...who knows.
3. The motor contacts could be dirty. All the 4x4 guys have the same few issues with that stuff. Search for any of many threads about that fix....
