5. **Dry the Window Channel Completely:** Use a clean, dry microfiber cloth to thoroughly dry the window channel. Ensure there is no moisture remaining before proceeding to the next step. Moisture can prevent proper adhesion.
6. **Apply Adhesive Promoter (Optional but Recommended):** If you are using adhesive promoter, apply it to the window channel according to the manufacturer’s instructions. Typically, this involves wiping the promoter onto the area where the deflector will attach. Allow the promoter to dry completely before proceeding. This usually takes a few minutes, but refer to the product instructions for specific drying times.
**Step 2: Test Fit the Wind Deflector**
Before removing the adhesive backing, it’s essential to test fit the wind deflector to ensure proper placement and fit. This step will help you identify any potential issues and make necessary adjustments before committing to the final installation.
1. **Position the Deflector:** Carefully insert the wind deflector into the window channel, aligning it with the top and front edges of the door frame. Do not force the deflector; it should slide in relatively easily.
2. **Check for Proper Fit:** Ensure that the deflector sits flush against the window channel and that there are no gaps or overlaps. Pay attention to the corners and edges of the deflector. It should conform to the shape of the window channel without any binding or distortion.
3. **Identify any Obstructions:** Check for any obstructions that might prevent the deflector from seating properly. This could include weather stripping, window regulators, or other components inside the door frame.
4. **Make Adjustments (if necessary):** If the deflector does not fit properly, try repositioning it slightly or bending it gently to conform to the shape of the window channel. If necessary, consult the manufacturer’s instructions for specific adjustment recommendations. Some deflectors may require slight trimming to fit perfectly.
5. **Remove the Deflector:** Once you are satisfied with the fit, carefully remove the deflector from the window channel.
**Step 3: Install the Wind Deflector**
Now that you have prepared the surface and test-fitted the deflector, you are ready to proceed with the final installation.
