I bought my car used and found ARCO wiper blades on it. I bought new ones at the dealer and realized that this car has two different size blades. I don't know where the bigger one goes. Seems to work on both sides??? Would somebody let me know where the longer blade goes. It is a US car.
Thanks.

 

Driver Side = Short
Passenger = Long

 

Our wipers are very unusual. The sweep of the driver's side wiper reaches the extreme upper limits of the glass [most cars leave a couple of inches of unwiped glass at the very top]. Where I live, the property owner's sticker is supposed to go on the upper center of the windshield; I had to use the alternate location, which is the lower left. However, in the course of looking around, I have discovered that very few cars require that alternate location.
