Do these visors require drilling or adhesive to install?

Installation method is not specified in the product data. Verify fitment and mounting style before committing to adhesive or fasteners — some window visors are adhesive-mounted, others clamp to existing trim.

Will these visors block rain from the windows when they're cracked open?

Window visors sit above the glass and direct water away from the interior when windows are partially open. They work best when mounted flush to the roofline.

Can I return or exchange these if they don't fit?

Check the return policy on your order confirmation. Fitment issues should be raised with customer service within the standard return window — have your vehicle information and photos of the fit ready.
