I have a 2008 honda ridgeline. one day i put it in park and it would not come back out of park. not only that, but the horn would not work, and the brake lights would not work. i found fuse#13 to be blown. i changed the fuse, and it blew it. I disconnected the brake pedal switch, and it still blew fuse # 13. so im figuring a short between fuse box and brake pedal. I take fuse box apart. Everything looks great inside fuse box. I put volt meter on hot side of 13 and get 12 volts. put meter on other side of fuse and get 0 volts...great. now on ohm meter, I go from 0 volt side to ground and get dead short. so i go inside truck to plug for brake switch and ohm every connection in brake plug harness to ground and all four wires show short to ground. any suggestions ? I see where harness goes into firewall, but a complete nightmare after that.

  • I also completely disconnected my trailer wiring harness, just incase that might have been the culprit. i also replaced the clock spring in the steering column.

  • Check the wiring diagram - that wire must supply more components than just the horn... All you need to do is find the short...

Owners manual will tell you what circuits are protected by fuse 13. Does fuse 13 blow when the brake pedal switch is disconnected? You may learn a Circuit unrelated to the brake lights/brake light switch is also protected by fuse 13 and he is causing the problem. How many amps is the fuse?
