Where is the '99 Nubira cabin air filter

It is certainly well hidden. Would like to replace it after all these years.

Look if it is at the same place than in Nubira2000, behind the vacuum black box which has two thin pipes.

You are right. Thanks!. Just wondered though, what the black box is.

This is a vacuum tank connected to the heater mode control knob trough the firewall. This selection knob actuates some flaps.
You can actuate (for some time) the flaps even with engine stopped. But I don't know why they do so!

This tank has a one-way check valve built in. The "S" mark (succion) goes to intake manifold.
