To find it:
1. Locate your interior fuse box: This is usually found under the dashboard, on the driver's side. Your owner's manual should have a diagram showing its location.
2. Consult your owner's manual: The owner's manual is your best resource. It should have a fuse diagram specifically for your 2001 Santa Fe model and trim level. This diagram will show you which fuse controls the blower motor. The fuse may be labeled "blower," "HVAC," "heater," or something similar. The amperage rating might also be listed.
3. Check the fuse visually: Once you've identified the suspected fuse, visually inspect it for a blown element (a broken wire or discoloration).
If you can't find it in the manual or by visual inspection, it's best to take your vehicle to a Hyundai dealer or a qualified mechanic. They have the resources to diagnose the problem accurately. Don't guess which fuse to replace; incorrect replacement can cause further damage.
