Where is the ac fuse in a 2000 Oldsmobile Alero?

The AC fuse in a 2000 Oldsmobile Alero isn't a single, dedicated fuse for the entire AC system. Instead, the Alero's AC system uses several fuses and relays to protect different components. You won't find one labeled "AC."

To find the potential problem areas, you need to consult your owner's manual. It will show you the fuse box locations (usually under the hood and possibly inside the car, near the driver's side) and a fuse panel diagram identifying each fuse's amperage and what circuit it protects. Look for fuses related to the A/C compressor, blower motor, and possibly the AC clutch.

In short: You need your owner's manual to locate the relevant fuses. Trying to find the wrong fuse can lead to further damage.
