Where is the horn fuse on a 2011 tundra?

The horn fuse on a 2011 Toyota Tundra is typically in the engine compartment fuse box, with a possible secondary fuse or relay in the interior fuse box behind the driver’s kick panel. Refer to the diagram on the fuse box cover to identify the exact slot and amperage for the HORN circuit.

Fuse locations to check

The horn circuit on the 2011 Tundra can be protected by a fuse in either the engine bay fuse box or, in some configurations, the interior fuse box. The diagram on each fuse box cover shows the exact location and rating for your truck.

• Engine compartment fuse/relay box: usually located near the left side of the engine bay, close to the firewall or strut tower. Look for a fuse labeled HORN or a HORN relay; the fuse is commonly 10A or 15A depending on the market.


• Interior fuse box (driver’s side kick panel): located behind the lower dash panel under the steering column. Check for a fuse labeled HORN or HORN RELAY in this box, especially if the horn fails even after replacing the under-hood fuse.

Note: Some Tundra trims or regional specifications place the horn control exclusively in the engine bay fuse box, without a dedicated interior horn fuse. Always verify with the diagram on the fuse box covers.

How to inspect and replace the horn fuse

Follow these steps to locate and test the fuse, and replace it if blown. A blown fuse is a common cause of a non-working horn.

1. Turn off the ignition and remove the key. Open the chosen fuse box and locate the HORN fuse or relay using the diagram on the cover.


2. Carefully pull the fuse with a fuse puller or needle-nose pliers and inspect whether the metal filament is broken or if the fuse is discolored.


3. If blown, replace with a fuse of the same amperage rating (typically 10A or 15A for the horn). Do not substitute a higher rating, which could damage wiring.


4. After replacement, test the horn by pressing the horn button. If it still does not sound, inspect the horn itself, the horn relay, and associated wiring. Consider testing with a multimeter or consulting a professional if the issue persists.

If you cannot locate a blown fuse or if replacing the fuse does not restore horn function, the problem may lie with the horn unit, relay, wiring, or the vehicle’s body electrical control module. Seek professional service for a definitive diagnosis.

Summary

For a 2011 Toyota Tundra, start by checking the engine compartment fuse box for a HORN fuse, then inspect the interior fuse box if necessary. Use the diagram on the fuse box covers to identify the exact slot and amperage (commonly 10A or 15A). Replace blown fuses with the correct rating and test the horn again. If the horn still doesn’t work, examine the horn unit and relay, or consult a mechanic for further diagnosis. Always refer to your owner’s manual for the precise fuse layout specific to your truck’s market and trim.

Which fuse is for the horn?

The horn fuse location varies by vehicle, but it is often labeled "HORN" and can be identified using the fuse box diagram on the back of the fuse box cover. Common fuse amperages are 15A or 20A. To check, locate the fuse box, find the correct fuse using the diagram, pull it out, and inspect it for a broken metal strip.

Steps to find and check the horn fuse

1. Locate the fuse box: This is typically under the dashboard on the driver's side or in the engine bay. 
2. Find the correct fuse: Look for a diagram on the inside of the fuse box cover that labels each fuse. Find the fuse specifically labeled for the horn. 
3. Identify the amperage: The fuse will have an amperage rating printed on it, often 15A or 20A. 
4. Remove the fuse: Use a fuse puller or a pair of needle-nose pliers to pull the fuse straight out. 
5. Check the fuse: Hold the fuse up to the light. If the thin metal wire inside is broken, the fuse is blown and needs to be replaced. If the wire looks intact, the problem lies elsewhere, such as the horn relay or wiring. 
6. Replace if necessary: If the fuse is blown, insert a new fuse with the exact same amperage rating in its place.
