I tried the other pair on this evening and the SAME THING happened. The Michelin has no rivets It expect 2 small pieces of plastic to hold a 26' arm in the middle of winterr? Are you kidding me. I looked at Michelin Guardian Hybrid wipers carefully comparing the former Bosch Wipers to these the Bosch wipers have a RIVETED conniption piece where the arms on the connector arm of the wiper meet. I turned on my wipers and ** BINGO* Both wipers popped off the arms and the arms 'my windshield' on the way down WTH?

So I ran deforster for 10 minutes clearing windshield completely. Next morning it was cold= 30 degrees and because I forgot to put Frost blocker on it seemed as if I had frost. Installation was tested in 50 degree conditions and Seemed to be ok. Cleaned the glass both front and on the inside and tested blades on my Top lock wiper arm of the XC60 Polestar that I own. Purchased 2 pair at they arrived Sunday (Jan 9th.2021) Since it was a 50 degree day in Virginia I put them on taking off the set of Bosch wipers that they were replacing and the passenger side was a little worn.

Does costco install wiper blades
