3. Setup (Installation Instructions)
Installation is designed to be straightforward, typically taking 10-15 minutes per side. No drilling is required as these are in-channel deflectors.
Preparation:
- Clean the window channels thoroughly to remove any dust, dirt, or debris. Ensure the channels are completely dry before proceeding.
- Test fit each rain guard to its corresponding window channel to familiarize yourself with its placement.
Installation Steps:
- Carefully remove the protective film from the double-sided adhesive on the rain guard.
- Slide the rain guard into the window channel, starting from one end and gently working your way across. Ensure it is fully seated and aligned within the channel.
- Press firmly along the entire length of the rain guard within the channel to ensure the adhesive makes good contact.
- Insert the provided clips at the outermost pillar positions of the window channel. Avoid placing clips in the middle to prevent interference with window operation. Use the crowbar tool to assist in seating the clips securely.
- Once installed, slowly raise the window. If you encounter resistance or the window automatically lowers, re-adjust the rain guard and clips until the window operates smoothly.
Important Post-Installation Notes:
- Keep windows closed for 72 hours after installation to allow the adhesive to cure properly.
- Avoid washing your vehicle or driving at high speeds for 24 hours after installation.
- The double protection of clips and tape ensures a sturdy installation. It is recommended to use both for optimal security.

6. Troubleshooting
Window Not Closing Properly:
If your window encounters resistance or automatically rolls down after installation, this typically indicates interference with the rain guard or clips. This can be caused by:
- Improper Seating: The rain guard may not be fully inserted into the window channel.
- Clip Placement: Clips might be placed in a position that obstructs the window's path. Ensure clips are at the outermost pillar positions.
- Adhesive Curing: The adhesive may not have fully cured, causing slight movement. Ensure windows remain closed for the recommended 72 hours.
Solution: Gently re-adjust the rain guard and clips. Ensure the visor is fully seated and aligned. Raise the window slowly and observe for any points of contact. If resistance occurs, lower the window and make small adjustments until it closes smoothly.

Rain Guard Not Sticking / Falling Off:
If the rain guard does not adhere properly or falls off, consider the following:
- Insufficient Cleaning: The window channel may not have been clean or dry enough during installation.
- Improper Curing: The adhesive requires time to bond. Ensure the 72-hour window-closed period is observed.
- Lack of Clips: While adhesive provides initial hold, the clips are essential for long-term security, especially for in-channel designs.
Solution: Re-clean and dry the window channel. If necessary, apply new double-sided automotive-grade adhesive tape. Reinstall the rain guard, ensuring clips are correctly positioned and the window remains closed for the full curing period.
