In the 2000 BMW 323i, the air filter is located in the engine compartment. You can find it housed in a rectangular air filter box, which is typically situated near the front of the engine bay, on the driver's side.

The relay for the blower motor on a 2000 BMW 323i is typically located in the fuse box under the dashboard on the driver's side.
