Oldsmobile alero ac button doesn't work?

If the A/C button on your Oldsmobile Alero isn't working, it could be due to a blown fuse, a faulty A/C relay, or an issue with the climate control module. Start by checking the fuse associated with the A/C system in the fuse box. If the fuse is intact, inspect the relay and wiring for any damage. If those components are functioning, the problem may be within the climate control system itself, which may require professional diagnosis.
