Have a problem that just recently happened. I left the top off and it rained. Drove the jeep the next day and the horn didn’t work. The fuse was blown so I replaced it. After I replaced it I got a check engine light for TPS high circuit. Take the fuse out and it’s gone.

If I put the fuse back in it’ll come right back. Pull the relay for the horn out and same thing no more light.

What could be doing this? Bad ground? Short? Clockspring? Bad fuse box?
 
Your clockspring got wet inside and one of its connections goes to the same databus the TPS connects to. It can mimic a bad TPS when that happens.

I left the fuse out and has been working good. Then today I blew a fuse for turn signals. Replaced it and it automatically blew. Assuming this may be related to the clockspring being bad. Can I disconnect it to see if it is causing the short?
