Hello I will help you with your question,
The horn relay and horn activation fuse is the #4 10 amp red fuse in the underhood fuse block.
Let me know how I can help
How to unplug so my horn will stop blowing? It has been going off randomly, and I need to stop for now.
All that needs to be done is to grasp the fuse and pull straight up. There is a fuse puller in the box but a pair of needlenose plies works better.
YOu would better to pull the horn relay which is the center relay of the three at the front of the box. The legend is on the lid of the box. Again, grasp it and pull straight up.
Please let me know how I can help
