Do not replace more than what failed
A broken A/C vent control tab does not always mean the entire vent assembly needs to be replaced. If the housing and louvers still work, the repair may only need the small part that lets you aim the airflow.
That is the core VentTabs repair: replace the broken control point and keep the factory vent in place.
Avoid unnecessary labor
Replacing a full assembly can mean more cost, more time, and more trim removal. A matched VentTab is designed to install quickly in most cases without tools or vent removal.
