To find the potential culprits, you need to consult your owner's manual. It will have a detailed fuse box diagram showing the fuse ratings and what each one protects. Look for fuses related to:
* Blower Motor: This is the most likely candidate.
* HVAC (Heating, Ventilation, and Air Conditioning): There might be a fuse specifically for the HVAC system.
There are typically two fuse boxes in a Buick Century:
* Under the hood: This box usually contains higher amperage fuses protecting larger components.
* Inside the car: Often located under the dashboard, near the steering column or in the center console, this contains lower amperage fuses for interior components.
Without your owner's manual, I can't give you the exact location. Searching online for "2000 Buick Century fuse box diagram" might yield a helpful image, but double-check against your owner's manual for accuracy.
Troubleshooting Steps:
1. Check your owner's manual: This is the most crucial step.
2. Inspect the fuses: Carefully examine the fuses in both fuse boxes. Look for any that are blown (the internal wire will be broken or melted).
3. Test the fuses: If you're unsure, use a fuse tester to confirm if they are blown.
4. Check the blower motor resistor: This component controls fan speed. A faulty resistor can prevent the blower motor from working, or limit its speeds. This is often located under the dashboard.
5. Check the blower motor itself: If fuses and the resistor are good, the motor could be faulty.
If you're uncomfortable working with car electrical systems, it's best to take your Buick to a qualified mechanic. Incorrectly handling fuses or electrical components can cause further damage.
