Bosch Icons (I believe) are Bosch's premium line. I'm honestly perplexed why you are cycling through so many blades. I drive about 1000 miles/month and only a fraction of that is in the rain, mid-Atlantic region not near the ocean.

I try to keep the blades clean, wiping with dish detergent if I pick up diesel fumes or oil from road splatter. Bosch Icon seems to be the best I've tried so far. I've never been able to get more than about 6 months before the blades begin to streak so bad that night driving in mist or rain becomes intolerable - pretty much no matter what brand blades I use and I've tried most of them over many years. Interstate battery had a 8 year warranty battery…had that in my other truck before I sold it…still going.I am amazed by those who report 1 to 3 years wiper blade life. Yes I am sure you heard of products that can last a life time.(some honest)….even a 100,000 mile tire was invented…purchase by another tire company…and NEVER seen again…lol I once own a triple blade wipers the offer a lifetime …it lasted almost 13 years…before the plastic brackets fell apart….but the rubber blades.were still functional.best wiper blades I ever own! I kept the original wipers and I will purchase and replace the blade, back-up…after the Goodyears wear out.(Hawaii)

Several Tacoma owners says these blade replacements last longer….mine went 3 years…but actually needed sooner… Finally had to replaced wind shield wipers… Costco’s Goodyear blades.$6.99 each.22” & 20”…īut I saw a couple of YouTube’s videos.showing ‘How to replace just the blades”.cost approx $20.00 from Toyota dealers…looks like a very easy thing to do…those springs need to be replace correctly.a left & right side.and notches in the right directions.

Does costco install wiper blades free
