how to repair a cracked windshield
The 2014 Toyota Corolla has 3 windshield replacement options.
1. FW 3473 Standard
2. FW 3838 Acoustic Windshield - Best Option Without Rain Sensor
3. FW 3486 Acoustic Windshield & Rain Sensor
From 2012 to 2016 Toyota Corolla as used the same part numbers. If your car has a rain Sensor you must use part number FW3486 and it already has the acoustic sound barrier.
I recommend always using part number FW3838 for a Toyota Corolla from 2012 - 16 without a rain sensor. The cost is a little more but makes the car quieter.
