Unfortunately, the exact location within that panel varies slightly depending on the trim level and options on your specific Monte Carlo. You'll need to consult your owner's manual. It should have a diagram showing the fuse box layout and identifying which fuse controls the blower motor.
If you don't have the owner's manual:
1. Locate the under-dash fuse panel: It's usually found under the dashboard on the driver's side, often near the steering column. You might need to open a small access door.
2. Look for the fuse panel diagram: There's usually a diagram printed on the inside of the fuse panel cover or on a separate sticker nearby. This diagram will show the location and amperage of each fuse.
3. Look for a fuse labeled "blower," "HVAC," "heater," or a similar description: The amperage will likely be fairly high (15-30 amps is common for blower motors).
If you can't find it using the diagram or if multiple fuses appear potentially responsible, it's best to consult a trusted mechanic or auto parts store. They can usually help you quickly identify the correct fuse.
