Mine came with the flex type on it already. What the dealer didn't do is remove the shipping protectors from the wiper blades. And I never did either. Good thing they didn't scratch the windshield when I used them. I actually used them through an entire rain storm before I realized the next day (after thinking they didn't do very well) that the shipping protector was never removed. Kind of embarrased to admit this, but maybe that is what is happening to you???
Thanks JOEHORNBACK!!!! I'm embarrassed as well, I've bought at least a dozen new cars in my life and never had to remove a shipping protector off the windshield blades. But after reading your meassage I went out in the garage and tried pulling the blade off and sure enough there was a protector on them. I feel like the lady who calls 9-1-1 to say she is locked in the car and can't get out, the police officer tells her to look at the top of the door and lift the knob up. That's whats cool about these forums, you can learn such simple things that you never think of from other people. Thanks again
