Where is the radio fuse on a 1999 Toyota Avalon?
The radio fuse in a 1999 Toyota Avalon is typically located in the interior fuse box under the driver’s dash, usually labeled RADIO or AUDIO and rated at 10A or 15A. If you don’t find the fuse there, check the under-hood fuse box and refer to the owner’s manual for the exact fuse number and amperage for your specific trim. This guide walks you through the most common locations and how to verify the fuse is working.
Common location and how to identify it
The starting point is the interior fuse box on the driver’s side, mounted under the dash. The easiest way to identify the correct fuse is to check the fuse box cover or a label inside the panel, which usually marks the “RADIO” or “AUDIO” fuse and indicates its amperage. If the label isn’t clear, a quick visual check of fuses in the box can help you spot the one connected to the radio circuit.
Below is a practical step-by-step approach to locate and inspect the radio fuse in the interior fuse box.
- Open the driver’s-side fuse panel located under the dash near the knee area. Use the panel latch to release and pull the cover off.
- Look for a fuse labeled RADIO, RAD, AUDIO, or something similar on the fuse diagram found on the panel cover or inside the fuse box.
- Use the fuse puller (or needle-nose pliers) to remove the suspected radio fuse and inspect the metal filament. If the filament is broken or the fuse is visibly damaged, it’s blown.
- Replace the blown fuse with a fuse of the same amperage (usually 10A or 15A for the radio). Do not exceed the specified rating.
- Reinsert the fuse, reconnect power, and test the radio to confirm it’s functioning again.
If the radio still doesn’t work after replacing the fuse, proceed to check related circuits and connections as described below.
What to check if the interior fuse isn’t the problem
While the interior fuse box is the primary suspect, some Avalons may route power to the radio through other fuses or circuits. It helps to confirm whether another fuse or wiring issue could be at fault.
- Inspect the under-hood fuse box for any fuse labeled RADIO or AUDIO, or for a circuit feeding the radio. Some markets or trims may route the radio power differently, though this is less common.
- Verify that ignition/ACC power is available to the radio when the key is in the ACC or ON position. If power is absent there, the issue could be a related ignition/ACC fuse or wiring problem.
- Check for loose or corroded connectors behind the radio or at the antenna/ground connections, which can imitate a blown fuse by causing no power or poor reception.
- If the radio still fails after these checks, consider consulting a qualified technician or referencing the vehicle’s service manual for the exact fuse mapping for your production year and trim.
Summary
For a 1999 Toyota Avalon, the most likely radio fuse is in the interior fuse box under the driver’s dash, labeled RADIO or AUDIO and rated at 10A or 15A. If inspection of this fuse doesn’t resolve the issue, inspect related circuits in the under-hood fuse box and verify ignition/ACC power, then consult the owner’s manual or a professional if necessary. Keeping to the correct amperage and confirming proper labeling are essential steps to restoring radio function safely.
How many miles will a 1999 Toyota Avalon last?
200,000 miles
The vehicle is widely praised for its exceptional reliability and longevity, with many owners reporting over 200,000 miles of trouble-free use.
How to tell if a Toyota fuse is blown?
So here's one that's blown we have power on one one side not on the other. These ones are all looking good go right down the line. Here test them all. As you can see this is a quick way of doing. It.
How do I know which fuse is for the radio?
The radio is controlled by at least one fuse, often labeled "RADIO" or "AUDIO," which is typically found in a fuse box under the dashboard or under the hood. Some vehicles may have a second fuse, labeled "ACC" or related to the "infotainment" or "amplifier" systems, that also needs to be checked. To find the specific fuse for your car, check the owner's manual or the diagram on the fuse box lid, as the location and number can vary by make and model.

How to locate and check the fuse
- Check the fuse box diagram: Open the fuse box, usually located under the dashboard on the driver's side or under the hood, and find the diagram on the lid or in your owner's manual.
- Identify the fuse: Look for the fuse labeled "RADIO," "AUDIO," or sometimes "ACC" (for accessory) or "AMP" (for amplifier).
- Inspect the fuse: Use a fuse puller or needle-nose pliers to remove the fuse. Look for a broken or discolored metal filament inside. If it is broken, the fuse is blown.
- Replace the fuse: If the fuse is blown, replace it with a new one that has the exact same amperage rating. Using a higher amperage fuse can damage the system or cause a fire.
- Test again: If the new fuse blows immediately, there is likely a short in the wiring, and you should seek professional diagnosis.
