The fuse for the heater fan motor in your 2007 Toyota Camry is located in the under-dash fuse block, which is to the left of the driver's foot well. The fuse is labeled as "Heater/AC" and is a 10-amp fuse.
Here are the steps to access and replace the fuse:
1. Turn off the engine and allow it to cool down.
2. Open the driver's door and remove the floor mat.
3. Locate the fuse block cover to the left of the driver's foot well.
4. Press the tab on the fuse block cover and remove it.
5. Locate the "Heater/AC" fuse. It should be the third fuse from the left in the top row.
6. Use a fuse puller or needle-nose pliers to remove the fuse from its socket.
7. Inspect the fuse for any damage or breaks. If the fuse is blown, replace it with a new 10-amp fuse.
8. Reinstall the fuse block cover and floor mat.
Please note that if the heater fan motor fuse blows again, it is likely due to a problem with the fan motor or its wiring. In this case, it is recommended to have the vehicle inspected by a qualified mechanic to determine the exact cause of the problem and to have it repaired.
