The Idle Air Control (IAC) valve on a 2004 Buick Rendezvous is located on the throttle body, which is situated on the intake manifold. To access it, you may need to remove the air intake duct and possibly other components for better visibility and access. The IAC valve is typically mounted with two screws and has an electrical connector attached to it. Make sure to disconnect the battery before attempting any repairs or replacements.
