Where is the fuse for the air conditioning compressor of a 2009 Audi A6 located?

Audi A6L air conditioning compressor fuse is located in the black fuse box next to the battery in the engine compartment. Fuse-related precautions: 1. Using fuses that do not meet specifications may cause fires and injuries. 2. Never install a fuse that exceeds the rated current value. 3. Never repair a damaged fuse. 4. Never use metal strips, paper clips, or similar metal objects as substitutes for fuses. Below is an introduction to air conditioning maintenance: 1. Comprehensive inspection of the air conditioning system: When using the air conditioning for the first time in summer, first check the air conditioning system, such as checking the refrigerant through the reservoir and whether the air filter is too dirty, whether there are foreign objects in the radiator, etc. 2. Pay attention to the cleaning of the air conditioning: The air filter should be replaced regularly, otherwise the air conditioning will produce a musty smell. In addition, the condenser should also be cleaned regularly, and the water tank should be removed for thorough cleaning.
My 2009 A6 had its AC compressor fail before, and the first step was also to check the fuses. The AC fuses in this car are mainly hidden in two places: near the left front door, there's a small panel under the dashboard by the driver's shin—pry it open to find the first fuse box; and another set is in the black box at the front right of the engine bay. I recommend first looking for the diagram in the user manual. If you can't find it, you'll have to check each one—the compressor fuse usually has a small snowflake icon or is labeled AC/Fan, typically a 15A or 30A blue/yellow piece. Once during a heavy rainstorm, I found a blown fuse because its surface was blackened. When replacing it, remember to turn off the ignition to cut power, and test the AC circuit for shorts—otherwise, the fuse might blow again instantly. All you need are plastic tweezers and a multimeter; don't mess with the wiring yourself.
When repairing the A/C of an Audi A6, I often encounter fuse issues, especially with the compressor protection circuit in the 2009 model, which is prone to burning out. The location is near the driver's left foot, close to the center console. If you look down, you'll see a plastic cover. Pry it open to reveal the main fuse box. Remember to use a flathead screwdriver to gently pry it open to avoid scratching the interior. The markings inside aren't very clear; you'll need to look for slot No. 23 or a 10A flat fuse labeled 'Klima.' If the compressor suddenly stops working but the fan is still running, there's a 90% chance this fuse is blown. Last month, I helped a friend replace it, and he also cleaned the filter before the problem was resolved. Don't use off-brand spare parts; the original part only costs about twenty bucks.
