If the A/C vents in your Toyota Sienna are broken or not functioning, you've come to the right place. Toyota dealerships charge $150+ to replace a vent, but there's a more affordable and better solution. Instead of replacing the entire vent, just replace the Venttab. It's simpler, much cheaper, and doesn't require any tools.
These particular tabs are designed to fit the front middle and side vents of a Toyota Sienna.
To install, just center the gear mechanism behind the louvers and slide into place.
The patented, one-piece Venttabs design allows you to install it without removal of the vent or the vent louvers (fins) To install, just locate the vertical post behind the louvers of the vent and slide the tab into place.
