I don't know if anyone has posted this yet, but I replaced both front wipers today with Bosch Icons. I upgraded the size to 21" from the stock 20". I don't know why Ford always puts small wipers on their vehicles. The book calls for the 2007 Expedition to get Icon 420A on the drivers side and 420B on the passengers side. I installed 421A and 421B. I have read people putting 22" blades on, but I thought 21" was plenty and they make 100% contact with the windshield.

I am a little OCD about my windshield and these wipers are a big upgrade over stock.

 

My wipers were about 22" on both sides and I switched last night to ICONs. 22 driver and 21 pass. I had to take what they had. I have ICONS on all my cars. Love them. I think you will too.

 

Geeee, I wish it rained here in San Diego so I could use my wipers, I think they still work? Kind of like the heated side view mirrors, the light comes on, so I guess they work too.
